FAQ's

Sure can! This powerful product cleans them all - from roofs to floors, bricks to pools, there’s no need to buy separate products for all these surfaces. Great for all types of Roofs including Decramastic, Clay tile, Concrete tile, Super 6, Fibrolite, Colour steel, Zincalume (iron roof)

In some circumstances, you may see an instant reaction take place. For instance, when getting rid of moss, you will probably see it go brown straight away. Surfaces such as concrete may turn an orange-brown colour after it has been sprayed. This temporary change is a good sign as this is a natural reaction between the growth and the Wet & Forget’s Rapid Application solution.

Good news. After the initial clean, you should not have to wait to see results. Instead, an annual spray of Wet & Forget’s Rapid Application should keep the moss, lichen, algae and mould away. However, if any new growth appears reapply sooner and keep it at bay.

Not under normal circumstances, but normal safety precautions prevail. Keep your precious pets off the surfaces until the surface is totally dry. This prevents the cute little critters licking product off their fur or paws. We say "Don't let your moggy or Doggy's paws get soggy! If they accidentally walk or sit in the product - wash their feet and bottoms with fresh water as a precaution.

They are ‘sister’ products. The coverage is the same, but the dilution rates are different because the way you apply them is different. Wet and Forget needs a garden sprayer while Rapid Application needs just a hose to apply and can reach up to 8m.

There is no definitive time - but of course all these growths such as lichen, moss, mould and algae appear more in the winter months when the exterior surfaces are damp and wet which are the perfect conditions for these growths to thrive. The best time to apply Wet & Forget’s ‘Rapid Application’ is when you see the first signs of green. Always apply to a dry surface so you do need to wait for that right day. If you can stop it at the green stage, then the cleaning is so much quicker than when the surface is black - which is a sure sign that the contamination has been there for a much longer time. Be proactive and get rid of it at the first visible sign.

Shower Witch will only remove surface mould - but not if it is permanently sealed in silicon sealants or grouting.

Double Bubble is a combination of cutting edge surfactants to help dissolve dirt and grime. Rapid Application/Wet & Forget both target moss, mould, lichen, algae and black fungi contamination.

Hit the Deck removes heavy contamination of black mould from all timber surfaces. Timber, if left uncleaned for some time, will turn black with UV degraded layers of wood fibre. The biological growth stubbornly holds on to the timber. Once it reaches this state, standard cleaning methods are quite difficult.

It sure is! It biodegrades and will not affect or interfere with the aerobic on anaerobic bacteria that break down the waste.
