Product Description
GK Decking Cleaner is a high-performance, long-lasting solution designed for the effective removal of organic and microbiological soiling such as algae, lichen, mould, and bacteria from a variety of external hard surfaces. Suitable for decking and other outdoor areas, it ensures thorough cleaning without damaging the material.
Free from solvents, bleach, and acids, this cleaner is formulated to be gentle on surfaces while maintaining strong cleaning power. Importantly, it does not alter or discolour the treated surface, making it ideal for preserving the original appearance of decking and other exterior finishes.
