ProKleen Pro-Kleen Ultimate Composite Decking Cleaner 20L

From Pro-Kleen, the Ultimate Composite Decking Cleaner is a concentrated liquid treatment created to shift tough outdoor grime, including dirt, algae, moss and mould. Designed for composite decking and suitable for a wide range of hard outdoor surfaces, it helps restore the look of patios, pathways and fencing with a simple apply-and-leave approach.

Use in dry conditions when rain is not expected for at least 8 hours, and avoid applying in intense sunlight to maintain wet contact time. For light cleaning, dilute 1 part solution with 5 parts water; for heavier cleaning, use undiluted or dilute 1 part solution with 2 parts water. Apply with a pressure sprayer or watering can, agitate stubborn marks with a stiff-bristled brush, then allow 5–15 minutes dwell time without letting the surface dry out. Results appear in 2–3 days, with re-treatment recommended for heavy growth if needed. Made in the UK, the formula is biodegradable, non-corrosive, pH-neutral, bleach-free and acid-free, and is described as cruelty-free and vegan-friendly. Keep pets and children away from the area until fully dry.
