Mould & Algae Removers

Restore tired patios, roofs and paths with a mould and algae remover that works without scrubbing. Green and black growth makes outdoor surfaces look neglected and can make them dangerously slippery. This collection suits homeowners who want a low-effort way to clean large outdoor areas. It is also ideal for surfaces that are hard to reach or delicate to pressure wash. It saves hours of back-breaking scrubbing every year.

Wet and Forget mould, lichen and algae remover comes as a 5-litre concentrate that makes up to 30 litres of ready-to-use solution. After applying, the treatment continues to work with wind and rain over the following weeks, gradually cleaning the surface. It can be used on patios, paving, roofs, fences and garden furniture. No scrubbing, rinsing or pressure washing is required. Dilute the concentrate as instructed and apply on a dry day using a sprayer, covering the whole surface evenly. Results appear gradually, so patience is key, but the treatment carries on working with each shower of rain. Many people treat surfaces once a year to keep growth from returning.

We list concentrate volume and dilution clearly so you can estimate coverage. One concentrate bottle makes 30 litres, which keeps the cost per square metre low, and dilution details are taken from the label. As a trusted UK seller, we stock cleaning products with a strong reputation. Follow the label instructions and keep pets and children away during application.

Cleaner outdoor surfaces with minimal effort is a win for any home. Order Wet and Forget from Garden N Outdoor and let the weather do the work.
