Our legendary "set & forget" solution

The Ultimate Long-Term Moss, Mould & Lichen Treatment

Wet & Forget: Moss & Algae Remover is the ultimate outdoor cleaning hack for everyday heroes who want maximum results with minimum effort. Whether you are rejuvenating your roof and decks or restoring your pavers and garden paths, our legendary formula delivers a deep clean without the risk of surface damage.

Unlike harsh acidic cleaners that can etch or degrade building materials, our pH-8 formula is neutral and safe for almost any exterior surface. One application doesn't just clean; it creates a protective environment that keeps new growth at bay for up to a year, saving you from the cycle of constant maintenance. With no scrubbing required, the wind and rain do the heavy lifting for you. This 5L bottle makes 30 litres of product, providing coverage of up to 300m² (depending on surface porosity).

No harsh chemicals. No worries.

Tough on grime but kind to your surfaces.

How to use Wet & Forget: Moss & Algae Remover

Protect Your Plants

Thoroughly water any plants or gardens near the area you are treating before application to create a protective barrier.

Mix Your Solution

Mix 1 part Wet & Forget: Moss & Algae Remover with 5 parts water in a garden sprayer (e.g., 1L product to 5L water).

Saturate The Area

Saturate the dry surface with the solution until it is thoroughly wet. Sometimes lichen is tough and can require a two-step attack. Once the formula is applied, wait 15-20 minutes for it to penetrate, and then treat the area again.

Let The Elements Do The Scrubbing

Once you have finished, simply leave it! The wind and rain will work with the formula to clean the surface over time. Important: Don't forget to give your plants one last watering to rinse off any overspray.

A Helpful Tip From Our Experts

For surfaces heavily affected, return 15 minutes after your first application and coat the area again while it is still wet. This "double-soak" ensures the product penetrates the tough outer shell of the lichen to reach the living biology underneath.

Precautions

  • If you are likely to get overspray onto plants or grass, water the garden before application to create a barrier, and rinse plants down afterwards.
  • Use eye protection and rubber gloves when using this product, and always refer to the product label for safety directions.

I have been using Wet and Forget probably for a couple of decades and though I am aware of cheaper products I find Wet and Forget results last far longer than these other products.

I have used your product during the year with excellent results. My tiled roof was black with lichen. Now after almost 12 months it is clean and bright. I would highly recommend it to anyone.

I have used the products from this company over a long period, and have found them to be the best on the market. Being a NZ. company I have found it safe to shop online knowing that I will get what I order and there will be no problems, plus the products work very well.

Some months ago I purchased 5L of your product, Wet and Forget. I intended to use your product on pavers which had need of cleaning. My house is over 50yrs old and has a teracotta tile roof which was covered with moss and grime. One could hardly see the natural colour of the tiles. I was told by the builder the tiles needed to be replaced, with a quote of $6,000. I advised him that I would consider it. I decided to try Wet and Forget and used it all, hoping for the best. Meanwhile, I went away touring in my caravan for 4 months and on my return - to my horror - the roof tiles had been replaced!! I rang the builder accusing him of going ahead with replacement tiles without my authorization. He assured me he had not done any work at my house and was waiting for me to give the go ahead. At this point I realised Wet and Forget had done the job and my rood looks brand new. I cannot thank you enough. You may use this as a recommendation of your wonderful product at will.

I am a Wet&Forget repeat offender lol and won't use anything else. I can spray a very green driveway/path at 4 pm on a nice afternoon and by morning everything is pristine, I have had some instances where the green can vanish before my eyes. I will continue to come back for more. Councils should use this on lichen covered footpaths which would mean I don't have to do it in our street any more lol. Love it the MOST!!

I have used W&F for many years, it keeps algae, lichen and moss manageable on all my paths, deck etc. Definitely worth the effort.

A photo showing an area sprayed with wet and forget to the perimeter of our pathway to see if it works. Oh yes it does work! I have now purchased two extra 5L packs to finish the job. Great stuff. Thanks Wet and Forget

I just had to write and send you this photo of a house we brought a few months ago. As you can see it was in a real bad way. It was a real talking point to everyone who travelled past or played golf, as it fronted on to golf course. We got stuck into it with Wet and Forget and we got people stopping and saying, "What did you clean the place with?" I told so many people it was Wet and Forget that we were just about to put it on a poster at the front gate. Even the man next door has had to promote it. We have used Wet and Forget for year but never on a job as bad as this, so just wanted to say thank you for such a great product and all the hours of work wet and forget saved us. Thank you, thank you from the owners of the new, bright clean house where our son is proud to live in while his new house is being built.

I have used this particular product for at least 25 years. It does the job perfectly, removes all of the above. I now use it on my decking for maintenance, and paths as well to remove slim build up, and keep the paths looking great. In the past I used it to clean my tiled roof and it did a fantastic job. An amazing product. Thank you

Frequently Asked Questions on Wet & Forget: Moss & Algae Remover

Can I use this on my roof if I have a water tank?

You certainly can. However, you must disconnect or divert your rainwater collection system until you have had at least 36mm of rain to ensure all surfactants have been rinsed off the roof.
