Which Wet & Forget Outdoor Cleaner is right for your Job?
Wet & Forget comes in three application formats, each designed to remove mould, lichen and algae with the same effective results. The best option depends on the size of your patio or outdoor area, available equipment and whether you prefer greater control or convenience. Unlike many outdoor cleaning solutions, Wet & Forget is bleach-free and contains no harsh chemicals, making it safe to use on outdoor surfaces without causing damage or discolouration when used as directed.
Wet & Forget Concentrate Mould, Lichen & Algae Remover
For larger patios, paths and driveways where you want maximum coverage and greater control over application, Wet & Forget Concentrate is a strong choice.
The concentrated formula is diluted 1:5 with water and applied using a garden sprayer. Because you mix the solution yourself, you can prepare the amount you need and apply it evenly across larger outdoor surfaces.
It is particularly useful if you regularly clean larger areas and want a cost-effective format with flexible application, while still benefiting from Wet & Forget’s spray-and-leave approach.
Wet & Forget Rapid Application
For larger outdoor areas where speed and convenience are the priority, Rapid Application removes the need for measuring, mixing or preparing a separate garden sprayer.
Simply connect the bottle to a garden hose and spray. The built-in applicator mixes the solution as you work, helping you cover broad areas such as patios, driveways and paths quickly and evenly.
Rapid can cover up to 200m² in around 10 minutes and can spray up to 8 metres, making it especially useful for larger areas and surfaces that are more difficult to reach such as roofs, conservatories or exterior walls.
Wet & Forget Ready To Use
For smaller jobs, isolated patches and quick touch-ups, Wet & Forget Ready To Use offers the simplest application.
The formula is already mixed and comes with its own trigger sprayer, so there is no measuring, dilution or additional equipment required. Simply pick up the bottle, spray the affected area and leave the product to work.
It is ideal for areas such as patio edges, steps, paving corners and smaller patches of mould, lichen or algae that do not require a full patio treatment.
For larger areas, the Concentrate or Rapid Application formats will usually provide more suitable coverage.
