Cleaning Chemicals

At GK Products UK, our range of professional-grade exterior cleaning chemicals is formulated to cut through the toughest biological growth, staining, and surface contamination, delivering results that are visible from the first application.

We supply cleaning chemicals to both trade professionals and homeowners across the UK, with products built to handle the demands of the British climate, which means plenty of algae, black spot, lichen, and damp-driven mould.

Outdoor Cleaning Chemicals Designed for Real Results

Outdoor surfaces face a relentless assault from the elements. Rain, frost, UV exposure, and airborne organic matter create the perfect conditions for algae, mould, black spot, and rust to take hold. Standard household cleaners simply aren't designed for this.

Our outdoor cleaning chemicals are specifically formulated to penetrate and break down these contaminants at a chemical level, not just mask them on the surface.

Our range covers the full spectrum of exterior cleaning needs, including:

• Driveway cleaners that lift oil stains and ingrained dirt from block paving and tarmac
• Path and patio cleaners that remove algae and green growth from natural stone, concrete, and porcelain
• Decking cleaners that restore timber surfaces without stripping the wood's natural character
• Render cleaners that safely treat painted and unpainted render surfaces without causing damage
• Algae and black spot removers that deliver long-lasting results, not just a temporary fix
• Rust removers for stone and patio surfaces and staining caused by run-off

Every product in the GK range is tested for performance in real-world conditions, and many are available in concentrated formulas, giving you more value per litre and the flexibility to dilute to strength depending on the task.

Exterior Cleaning Chemicals for Trade and Home Use

Our exterior cleaning chemicals are trusted by landscapers, groundsworkers, building maintenance contractors, and property managers, but equally straightforward for confident DIYers who want professional results at home.

If you're preparing a surface for sealing, carrying out a seasonal clean, or dealing with a specific staining problem, you'll find the right product here.
