WET&FORGET is used all over the world to keep boats, marinas and harbours clean and safe for their customers. It keeps GRP sparkling and wood clean without scrubbing. It is used extensively to remove mould and slippery algae from walkways, pontoons, slipways, paths and walls. Whether used on plastic, wood or concrete, Wet and Forget will keep everything clean and safe for up to a year.

WET&FORGET is safe on Dacron, Mylar, Kevlar and Carbon Fibre. It's also great for cleaning sail covers, dodgers and sheets. Because Wet & Forget is a specially formulated surface biocide, it's non-caustic, non-acid and no bleach. This means you can use Wet & Forget on ANY outdoor surface, thereby keeping your yacht/boat or equipment (including your house and it's environment) looking like new all year around.

When diluted with water and applied, it immediately attacks that unsightly moss, mould, gunge and grime. Each time it rains, this safe, cleansing combination reactivates to help flush the moss, mould, gunge and grime without scouring the surface it has infested.
Wet & Forget is the safest, most effective way of removing moss, mould & gunge from ANY exterior surface. When applied, it immediately attacks that unsightly moss, mould, gunge & grime. Then Mother Nature takes over. The weathering process gently takes the decomposing material away bit by bit.

Frequently Asked Questions

  • Can I change the specified ratios given in the instructions?

Yes. For instance if the contamination is extreme, increase the strength for a quicker reaction. However, if you have cleaned the surface previously with Wet and Forget and you want to give it just a maintenance spray, you can decrease the strength if the contamination is light. The cleaning process will still be just as effective.

  • What is the dilution rate and coverage area?

Dilute Wet & Forget 1 part to 5 parts water. Every 5 Litre pack yields 30 litres of product to spray. With this you will get coverage of between 100 - 300 sq m depending on the porosity of the surface. ie painted surfaces will use less but porous surfaces readily absorb the product and therefore coverage could be in the range of 100-150sq m .

  • When is the best time to apply the product?

On a cool dry windless day and when no rain is expected for 4-5 hours. Often the evening is best when evaporation of the product is minimal. This will ensure that the surface to be treated stays wet with Wet & Forget for an extended period.

  • Do I have to use it all at once?

No, but good planning is essential. Work to a pattern so you know where you have started and stopped. The product is fine if left in the spray container as it does not deteriorate when it has been diluted. Plus it will not damage your garden sprayer as the product is not corrosive.

  • How long will it last in the container?

Forever and light does not damage the efficiency of the product. But always keep the cap done up tightly and the container out of reach of children.

  • How long will it take to work?

It is totally dependent on the intensity of the contamination. If it is really light you will see results within days. Otherwise it may take approximately 2-3 months to see improvements. Your concrete may turn an orangy brown when the Wet & Forget is applied. This is normal and shows you have had a good reaction. The discoloration will dissipate over a short period of time and is not permanent. The good news is that when you use it again the following season, the clean up will occur within weeks. In the very worst case scenario where contamination is extreme, it may take 6-12months.

  • If I am on tank water, can I use Wet and Forget on my roof?

Sure can. But you must disconnect the water supply to your tank for 3-4 weeks and have at least 5mm of rain to remove the concentrate. Wet & Forget has been used in rural communities for over 25 years to treat contaminated and "gungy" roofs.

  • Will it affect my pets?

Not under normal circumstances. However, keep your precious animals off the treated surface until it is dry, to ensure they don't ingest any of the product. If they accidentally walk or sit in the product wash their feet and bottoms with fresh water as a precaution.

  • Will it damage my plants?

Not unless you are directly spraying it onto the plants. If you accidentally do this, then rinse the plants down with water from the hose, or better still, protect them with paper or plastic to avoid overspray.

  • Will it remove the gunge off my timber decks?

Most definitely! But if your deck is older and has never been cleaned, it may be noticeably blackened with the contamination. In this case, it would be advantageous to wait a month after the application of Wet & Forget and give the area a light brush with a broom or scrubbing brush with warm water to remove it. The good news is that you should only have to do this once and then the maintenance becomes so easy.

  • Will Wet & Forget get moss out of lawns?

Sure will! Moss on lawns Firstly lightly water the lawn but not enough to saturate the moss. Do this late in the day when the sun is low so that evaporation is kept to a minimum. Dilute the 5Litre Wet & Forget 7 parts water to 1 part Wet & Forget and spot spray the moss. You may have to give it a couple of goes until you have it under control. At worst you may get slight burning on the grass but it will recover very quickly. Rake the dead moss out. Broadcast area with garden lime to change the ph levels. If it's early spring or autumn, overseed & fertilise
