ProKleen Pro-Kleen Ultimate Composite Decking Cleaner 10L

From Pro-Kleen, Ultimate Composite Decking Cleaner is a concentrated liquid treatment for lifting tough outdoor grime from composite decking and other hard surfaces. Designed to tackle dirt, algae, moss and mould, it helps restore the look of weathered areas across patios, pathways and fencing, with a simple apply-and-leave approach that suits both home and commercial settings.

The 5:1 concentrated formula can be diluted to suit lighter cleaning or used stronger for heavy-duty jobs, then applied with a pressure sprayer or watering can. Allow it to work for 5–15 minutes without drying out; results appear in 2–3 days, with re-treatment recommended for heavy growth. Biodegradable, non-corrosive, pH-neutral, bleach-free and acid-free, it is also described as cruelty-free and vegan-friendly. A 2-year guarantee is included.
