Methods For Removing Algae From Exterior Paint?

To remove algae and mold from exterior painted wood, use water, snow foam, car shampoo, microfiber wash mitt, soft brush, and an antimicrobial APC. If left uncleaned, it can lead to structural damage and increased health hazards. Mildew and mold are signs of moisture, and allowing them to grow on surfaces can be detrimental.

To remove mildew, pour warm water into a bucket, add a cupful of household bleach, and scrub the affected areas with a stiff brush. Proper moisture management is essential to prevent algae growth. Algae doesn’t have to be a persistent headache or damaging to your home’s exterior. With the right products, you can do a deep cleaning without the extra time and effort.

To avoid algae growth, reduce moisture on surfaces or apply anti-algal properties. Control the amount of sunlight and shade that hits the area as this can cause damage. Preparing your home’s exterior before painting is essential, and some circumstances, like mold and mildew, can make cleaning more challenging.

Alkaline cleaners like washing soda or trisodium phosphate can be added for extra cleaning. Therma-Tech and Doff steam cleaning is the best way to effectively remove algae from any type of painted exterior surface. Mixing sodium hypochlorite and water can remove algae but can also strip paint or leave streaks on the paint.

One economical and safe way to remove algae is with a solution of vinegar and water. Mix one part vinegar with four parts water in a spray bottle and apply it to the affected area. Apply a fungicide wash to the effected areas by brushing it on or spraying it on.

Periodic cleaning of exterior walls can prevent the buildup of substances that algae and moss feed on. Soft or gentle pressure washing can help.

Does vinegar kill algae?

Algae is a major issue in garden fountains, causing ugly appearances and harming plants, birds, and insects. White vinegar can be used to quickly kill algae, but it is not harmful to birds, insects, or most plants. A mixture of water and white vinegar can be used to spray the area, rinse the surface with water, and then pour the vinegar directly on the surface and scrub with a toothbrush. The more algae left behind, the quicker it can grow back and take over the pond.

A high-quality pump is crucial for a clean and sanitary fountain. Lower-quality pumps can cause flow performance issues, making it easier for algae and bacteria to spread, tainting the water’s quality and color. If you have a cheap plastic pump, upgrading to a high-performance pump like Pentair can help prevent technical issues and ensure higher flow performance for a longer period of time.

Allow the solution to sit on the algae for at least 15 minutes before scrubbing it away with a brush. The time it takes for paint to cover and hide algae depends on factors like the type of paint used, the surface being painted, and the number of coats applied. Typically, one or two coats of paint can achieve complete coverage, but if the algae marks are stubborn, a primer may be necessary before painting.

Is bleach or vinegar better for algae?

Vinegar is a natural and non-toxic remedy for killing mold and bacteria, especially on porous surfaces like carpets and upholstery. It can penetrate deep into the pores of the surface, killing around 82 mold species. The US EPA approves vinegar for use in dense mold areas, and its penetration power can kill mold at its roots. White vinegar, a mild acid, can kill around 82 mold species. However, it is important to wear protective gloves and glasses before using vinegar, as it may cause irritation and stinging sensations.

To use vinegar, spray it generously onto the moldy surface, let it sit for an hour, then wipe it clean with water and allow it to dry. Repeat this process several days for a mold-free surface. Avoid mixing vinegar with peroxide or other substances, as they may cause poisonous fumes. Bleach is toxic and should only be used if there is a small amount of mold in your house.

  • You offer some good advice for home owners that makes it easy to clean their property with a quick connection to a garden hose but the main ingredient in 30 second cleaner Is Sodium Hypocrite (AKA bleach / chlorine). Is simple household cleaning solution is 1 gal of bleach to 4 gal of water. Or 1 – 1 1/2 % bleach solution to whatever quantity is needed. This will save the householder many $.

  • I used the 30-Second cleaner on your recommendation and it worked beautifully! I’m glad I bought a 3-pack from Amazon because you’ve got maybe a minute or two of spraying and it was empty. The second sprayer completed the side of the house. Remember to spray underneath the siding due to the ridge on the siding. Oh, and when you spray make sure you watch where the wind is blowing or standing underneath because it will splash on you which doesn’t burn or irritate your skin. I didn’t see Rueman84’s (post below) The reason i mention it is because the little bit of backsplash got onto a decent shirt I was wearing and caused the blue in the shirt to turn into pink spots although I did not detect any bleach in the product but, it’s worth changing into clothes you don’t care about. One more hint…..before you throw away the sprayer, pry out the rubber washer which is actually high quality and use it for your garden hoses when they wear out.

  • Just had my house pressure washed a week ago. If only I had seen this article would have saved me a lot of money!! Well, at least now I know what to do next time. The main reason I had the house done is that I am 72 years old, a woman with some health problems, and thought I couldn’t do it myself. Nope, I can handle this. thanks for the article. I hit the subscribe button.

  • Thanks for this article. I actually work at Home Depot and stock this stuff on the shelf all the time (it sells like hotcakes). I have a problem with algae on my white aluminum siding and wondered if this really works. (There are so many brands that claim the same thing.) I’ll be taking your recommendation and buying the sprayer and the refill as well. Again, thanks!

  • I didn’t know they used vinyl siding in the south. This is the first time I’ve ever seen it. The homes in my area are hardboard siding or Hardy Plank. You definitely don’t want to get water up under and behind the siding. I would get up there on the ladder and shoot it at more of a right angle to the siding. If you get water up under the siding, those nails holding the siding on, are eventually going to rust. Then you’re going to have a problem with rust running down the side of the house from the nails. Even though they’re galvanized nails, they’ll eventually rust. Now if your siding interlocks securely and effectively prevents water from getting behind it, you don’t have anything to worry about.

  • OK, watched your article the other day. Went yesterday and bought the stuff. This morning I used it. Hands down, I shit you not, it works just as well and just as easy as he says it does. And, I did it his way. Pulled the red fan tab out and used hose pressure. Sprayed it twice with about 1 minute in between. The 2 minutes later I rinsed it. I sprayed from top down. I am sold. It worked beautifully!!! Hell, I went and told my neighbor and showed him. He was just as impressed. Did the vinyl on my whole house in 2 hours. Took my time, it was hot out. Last time it took a day of applying cleaner, scrubbing, then pressure washing. Never again, lmfao. TYVM!!!

  • OMG how happy I watched your article!! I’m a subscriber and believer in 30 seconds outdoor cleaner! I have deep mold on the front of house due to no sun. This stuff works as you described!! Man so easy ! Good advice keeping bottle full when using on high areas. And remember to remove red cap on nozzle for high areas.

  • Doc, I watched your article several times and went to Lowe’s and bought 30 second outdoor cleaner in the spay bottle but that would not be enough to finish the job, so I bought the one gallon concentrate. The question I have is, do I need to dilute the concentrate or do I just fill up the spray bottle ?

  • Doc …. I use the 30Second cleaner too. My house is tucked in the woods, all four sides. for hard to reach places, I pour the concentrate into a weed sprayer, mix 50/50 with water, spray, then hose away from a safe distance. My next use is to use my battery operated back pack sprayer to see if I can shoot 40 feet high (further than the hose can shoot) …. Last, I’ve noticed the cleaning results improve over time. This stuff works!!

  • DOC! Absolutely amazing👍 Waited after perusal your article, and then got the nerve to actually do it. It was so amazing, it was hard to believe. Used the Thirty Second Cleaner just as you described and my wife was amazed. I have siding on three sides of my house and completed the back side, and will finish tomorrow. Thank you for keeping it simple and real.

  • You turned me on to 30 Seconds in your fence article. Yesterday I tackled my wife’s 33-year old lawn tractor (JD 322) that had been sitting in a grass field, under the shade of a maple tree, for 10 years. “Moldy” would be an understatement. Mixed up a batch in a 1-gal pump sprayer 50-50, sprayed, hosed it off, repeated, and it did a fantastic job!

  • Great article I wish my house’s roof peak was this low, that is pretty simple for sure. No way you can hit the peak of a two and half story house with water pressure from a garden house. I use a foam cannon ( low pressure) on a lance on a small electric pressure washer and get fantastic results. Beautiful yard my man thanks for the share.

  • Been following you for a while as I have been in the golf business for some time….at my home I used a John Deere reel mower in my yard for many years, but just got too hard to keep up with maintenance….and I am now 76 years old….I switched to the McLane 10 years ago and have had no problem until this week…..do my own backlapping and work on the mower for the most part….but, I recently found it almost impossible to back lap. Put a new bedknife on last year and it was working great….now I cannot get the reel to adjust. It seems it will not move down on the left side. Have tried over and over…it will free wheel when I adjust up. But, I cannot get the reel to meet the bedknife for the perfect cut. Have you ever done a article on replacing the reel itself? I could not find it, or any article on it…would be a great addition to your collection. Appreciate your contribution to the turfgrass maintenance world. And, any other suggestions on adjusting the reel to the bedknife when a problem like mine exists.

  • Amazing product!!! Worked just like you said it would! Was figuring I needed an extension wand for my 2000PSI electric pressure washer in order to reach the second story of my home…to wash off the surface dirt that accumulates every year, and tackle the North side algae build-up that I’ve been dreading. N.B.- Been tackling it with a scrub brush and soapy water as far as I can reach for the past two years, but bought the pressure washer ultimately to get the higher regions. (Even bought the two piece “second story” spray tips – pink & blue – thinking that would do the trick. Joke was on me!) Decided to watch a few YouTube articles beforehand to pick up a few “pearls” before commencing, and found yours to be one of the most impressive. While at Home Depot picking up the extension wand, I grabbed a bottle of the RTU “30 Seconds” … as a ‘just in case’ plan A failed, although I really didn’t think it would be used. Extension was useless, so it exasperation I simply attached the bottle of 30 Seconds and “BAM!” …… the rest is history! Didn’t need to stay on but a few minutes (overcast day; 9-10 am), then rinsed clean off. Can’t thank you enough!!! No damage to vegetation beneath…rinsed before and after. P.S. While returning the extension wand, I was speaking to another woman waiting in line about how well the product worked, and she went to get some as her husband was going to do their house the next day! 😎

  • I have white vinyl on two sides of my house and trees are two feet away, so yes it has turned green! It is terrible!! Im doing this next weekend!! Going to get my attachment sprayer and the solution at Lowes and get on this!! Thanks for the info!! Any ideas on how to kill poison oak surrounding my trees?? When I use my weedeater to cut it back, I am so allergic to it, no matter what I do it gets on me and I suffer from it for weeks afterwards. Any help on this would be very much appreciated!!!

  • You’re not going to get water behind that siding if you use a pressure washer. There is a really tight lip where it fits together and you’re not going to get water through that. Now where the vertical joint is if you spray that away really hard and they didn’t overlap it far enough it could get back there but there’s no reason to go at that angle. Been washing siding for many years and usually I just normally use bleach solution with a pump sprayer. That stuff will work also. But I’ve never got water behind siding from washing it with a pressure cleaner. But this way is definitely easier than breaking the old pressure washer out I do agree with that.

  • I ordered the sprayer and 1 gallon from Home Depot and tried it out on the worst 2 sides of the house (they were pretty darned green). I have gray vinyl siding, live in Florida surrounded by big pine trees so it is shady. It did an OUTSTANDING JOB!!! It is better than when I hire the pressure washer guy for beaucoup bucks. I immediately ordered two more gallons. When I do the whole job next time It will take 2 gallons to do the whole house. Thank you it was super easy and I could do it all by myself:)

  • Man I bought a wrecker for a GRAND because of that green sht.. lmao.. It wasn’t a running wrecker, but had just about everything I wanted on it. Guy said, it’s bee sitting 20 yrs. LOL All I done was took a scrub brush to it and water hose. It’s all gone. 2 yrs. Hasn’t come back. Solid white. And the paint wasn’t harmed by it. Still has a gloss to it. It’s on a new chasey of course.

  • I got the 3 pack from Amazon and I did exactly as you said. My home looks great! You’re article is definitely the best. I heard you say remove the red tab and read it on the bottle. I’m a little slow but I got that removed on the 2nd spray 😂. I shared pics with friends and already got numerous complaints. Thank you so much for tips.❤❤

  • What are the chemicals? What do they do to your foundation plantings? What would they do to my 4 blueberry bushes in my food garden? I don’t want to even use bleach there. Lots of things can be made easy with caustic and toxic chemicals. I use a pressure washer with nothing but water and it gets everything, spider webs, stains, bird poop, mold and algae. Trouble is I can’t reach the high parts and don’t want to spray upwards to get moisture behind the siding. No way my well pump and pressure tank will create the pressure in this article. So Doc’s promise isn’t applicable to me or any homeowners around me.

  • I have a large jug of the “30 Minute” I recently bought. I don”t have the hose spray connector but I do have a pump sprayer I can use. What would the ratio of cleaner to water need to be? I have a berm home and I don’t have to get as high as you do so a pump sprayer and a step ladder will work fine for me.

  • The bat in the vent??? I had bats in my vent louvres once they could not get into attic cuz vents had a strong plastic mesh built into them preventing access but they would roost in louvres every day till I found out about it.I took a garden garden hose and connected it to my hot water tank drain valve and sprayed them down with scalding hot water and after two days of that those bats never returned.

  • pressure washer will work use chemical tips to apply chemicals and to rinse use same tips the chemical tips drop the psi and increases volume step back from the house there is a lot ways that will work you could also use a foam cannon you shouldnt rule out pressure washer just say that your way is one of the ways thats simple set up and works your 100% wrong that pressure washer not work pressure does not clean its the chemicals on the house long range chemical tips are available for 2-3 story homes this is 1st article of yours i dis agree

  • This triggered me because I am so sick due to mould/mold. I have been told that only people using proper protective gear should be removing mould – and not using bleach either (which just bleaches out the colour, it doesn’t kill the actual mould spores). You end up ingesting the spores/they go up your nose, and spreading them elsewhere. Especially damaging for people that already have autoimmune conditions/suppression too 🙁 That is one awesome tomato! Did you grow that yourself? 🤩
