"I used Wet & Forget Rapid on the house roof, moss and Lichen have turned white already. I recently cleaned the exterior plaster walls of the house with detergent based product, as I could not reach one high part with a brush extension.

Rapid Application & you’re done

Legendary Moss & Mould Removal for Roofs, Paths & Driveways

Whether you’re tackling a slippery driveway, a green timber deck, a moss-covered roof, Shade sails, trampoline net, pavers, green slippery decking or fences, Rapid Application is your legendary exterior cleaning sidekick. Featuring our innovative nozzle that reaches up to 8 metres, you can coat up to 100m² in just 5 minutes with your feet planted safely on the ground.

This non-caustic, bleach-free formula is designed to work entirely without scrubbing. Over time, natural weathering from the rain and wind will gently break down the biological growth, naturally washing away the moss, mould, and lichen to reveal a pristine surface. It’s the ultimate way to achieve maximum clean & minimum effort on your outdoor surfaces.

ALSO GREAT FOR...

Pool surrounds: concrete, tiles, sandstone, pavers, timber, painted surfaces. Even pool noodles (rinse thoroughly before use).

Caravans & motorhomes: safe on the exterior, canvas awnings, LPG tanks, and all outdoor gear.

Tennis courts: hard courts and artificial/sand-based surfaces.

Headstones & graves: bleach-free formula means it's safe on all stone types. No damage, no discolouration.

Tents & canvas: removes mould and algae without attacking stitching or fabric.

Solar panels: for heavy biological growth (use Window Witch for light grime).

Wooden fences, spouting, glasshouses, outdoor furniture & tarpaulins


Reach the Roof Without Leaving the Ground.

Ditch the dangerous ladder stunts & treat your second story with total control.

Why work up a sweat? Apply the formula & let the weather do the heavy lifting for you.

Innovative Sprayer

Innovative Sprayer

The innovative sprayer allows you to apply the formula up to 8 metres high, meaning you can treat those tricky nooks & crannies without ever reaching for a ladder.

How to use Rapid Application: Moss & Algae Remover

Prep The Garden

Before you start, thoroughly water any plants or lawn near the area you are treating. This protects them from any accidental drift.

Set Up Your Spray

Attach your garden hose to the Reach Nozzle. The "OFF" setting is clearly marked. Turn the dial to "WATER" to check your connection, then turn to "ON" to start mixing the formula.

Coat The Surface

Apply the product to a dry surface until it is thoroughly saturated. Fan Setting: Best for wide, flat areas like driveways, decks, and tennis courts. Jet Setting: Best for high spots like roofs, eaves, or second-storey cladding.

Let Nature Work

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

We call it "Rapid" Application because it is incredibly fast to apply (10 minutes vs. 5 hours with a standard sprayer). However, the results take time! This is a slow-acting formula that works with the wind and rain to gently clean the surface over weeks and months. Be patient, all good things take time! Rapid Results will last, and one application is enough to work really hard for you for an entire year.

For Lichen, 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

  • You must water nearby plants thoroughly before applying (to create a barrier) and after applying (to rinse away any overspray).
  • If you are on tank water, disconnect the water supply to your tank for at least 36mls of rain or 6 decent rainfalls before reconnecting.
  • While it is safe for almost all outdoor surfaces, if you have new concrete or pavers, check that they are fully cured before application.
  • Use eye protection and rubber gloves when using the product, and always refer to the product label for safety directions.

Fantastic product, spray, light scrub, rinse and done. So easy. Commonsense is required - it contains chemicals, rinse to stop processing

We are long term users of Wet and Forget around our lifestyle property. One of the main jobs is keeping our 6000 sq ft steel shed free of moss, algae, and lichen. For some years we used the original Wet and Forget in a spray pack, with husband on the roof spraying, and me on the ground pumping the mix up to him through the 30ft extension. Several times divorce was close. Then I discovered the Rapid Spray version. What used to take us a good few hours and two people, was reduced to one person, a hose and a ladder, and probably around 2 hours total - much of the time spent moving the ladder along. The Reach nozzle means I can reach the centre of the shed from the ladder. Much safer these days than either of us being up on the slippery roof. We spray the shed about 3 times a year, and it keeps it in good condition. If I could have one little improvement, it would be to have "Miss Muffet's Revenge" added to the mix, so that I can do the whole job in one go!! Thanks so much for a great product.

We've used this multiple times and it does work. Like most it's quite slow acting a d can take a few months to see lichen drop off. Not sure for moss and mould. Best to wear goggles hard to use without getting it on you and in eyes and it stings a lot. I do find it a bit expensive would only buy on sale

I recently purchased your Tiger's Paw & Shower Witch to really clean my daughter's bathroom before her house goes on the market. I never thought that the glass screen that is at the side of the bath would be sparkling again, but, it does! I was very impressed with ease of using Tigers Paw. Amazing product. Kim the store manager was magnificent in ensuring that we understood the product and how best to use it. How great to have that commitment to the product she sells. Will definitely recommend!

I've been looking for help to kill the weeds between the cobblestones in my court yard and the pesky ones that come up in my riverstone garden, without having to worry about my cat. This stuff is amazing. Weeds were gone in 2 hours and I could not be happier. I bought the concentrate and a sprayer so I can zap those weeds whenever they pop up with little effort. As an older person it's great to be able to spot spray without bending down. Very easy to mix as well so what's not to like. Already I have recommended to my neighbour and family. A must product in the garden shed!

Product works well on pine decks, only requiring medium scrubbing with the long handled brush. However with hardwood decks such as our purple heart deck it does require A LOT of scrubbing. Had to get knee pads and scrubbed on all fours for half a day with a hand held brush. I think I expected it to be easier to be honest but still happy with the outcome.

Amazing stuff! Extremely easy to clean the windows with a quick spray, wipe and rinse. No hard scrubbing is needed. My husband and I got out windows done on our 100m2 house in about 15 minutes. Used with the extending window cleaning pole, this stuff makes window cleaning a breeze.

It is el supremo at dissolving kitchen grease. Even stuff jif just gets bogged down in, gets dissolved in an instant. I was amazed at even on walls a light spray and wipe with a handy towel already damp with shower witch did the trick. We had some baskets that sit on top of the pantry ( for recipe books) that were pretty grimy, so I took them outside to them a good soaking. After a 10 min hose off , they were like new. I'm amazed.

Cannot recommend this product highly enough. Have a young cat (super stressed following the sudden passing of his cuddle buddy) indiscriminately urinating outside his litter tray. Have cleaned, vinegared & tried every product available (including heavy duty commercial enzyme cleaners). Nothing has worked. We were at our wits end and at the stage of carpet replacement when we spotted this product on a TV ad. Arrived within 48 hours of ordering and LOVE it! One application & the pong has definitely gone! If you have pets, you have to have this in your cleaning cupboard! Thankyou Wet & Forget for another amazing product!

Not going to lie, I was dubious that something could really do the job of removing pet smells, feel like I’ve tried everything on the market, but most things just mask the smell, not fix it! Sprayed this as soon as I got it on my carpet where my dog is guilty of reoffending.. got home from work the next day and went to the offending corner for a sniff…. And it’s less than half as offensive! Can’t wait to sniff that corner tomorrow (and that maybe the weirdest thing I’ve ever said on the internet) Highly recommend!!!
