Paths and Patio Cleaner

From stubborn black spot lichen to green algae, mould staining, and ingrained grime, outdoor paving accumulates problems that general cleaning simply can't resolve.

At GK Products UK, our path and patio cleaner range is built for every surface type and every staining challenge. We supply professional patio cleaner products to homeowners and trade customers across the UK because great results shouldn't require a contractor.

The Biggest Patio Cleaning Challenge: Black Spot

Search almost any patio cleaning forum or gardening community and you'll find the same question: how do I remove black spots from my patio?

Black spot is caused by a type of lichen that embeds itself into the pores of stone, concrete, and paving. It's resistant to pressure washing, resistant to most general-purpose cleaners, and grows back quickly if the underlying organism isn't properly killed.

Our GK Black Spot Remover is the dedicated patio black spot remover in our range, formulated specifically to penetrate stone and break down lichen at its root rather than bleaching the surface temporarily. It works on natural stone, porcelain, Indian sandstone, concrete, and block paving, making it the most effective patio black spot cleaner for the widest variety of surfaces. For patios where both black spot and algae are present, which is extremely common, a single application addresses both problems in one treatment.

Removing black spots from a patio with a purpose-made chemical is significantly more reliable than pressure washing alone. Customers who have tried multiple products before finding ours consistently report that the GK Black Spot Remover is the best black spot remover for patio surfaces they've used.

Patio Algae Remover: Keeping Green Growth Off Your Paving

After black spot, algae is the most common complaint on outdoor patio surfaces. Algae loves the damp, north-facing conditions that are common in UK gardens, and once it establishes on paving it creates a slippery, hazardous surface as well as an unsightly one.

Our GK Path & Patio Cleaner is formulated as a patio algae remover that kills biological growth, not just displaces it, giving results that last considerably longer than a pressure wash.

For patios affected by persistent algae, mould, or mildew, our GK Concentrated Fungicidal Wash offers a complementary treatment that inhibits regrowth after the initial clean, reducing the frequency of future maintenance.

Patio Cleaner for Every Surface Type

The right patio cleaner solution depends on what your paving is made from. Here's how our range addresses the most common surface types:

• Indian sandstone patio cleaner: Indian sandstone is porous and requires a cleaner that works at a lower pH to avoid damaging the stone's natural character. Our Path & Patio Cleaner is safe for use on Indian sandstone at the correct dilution.
• Natural stone patio cleaner: For limestone, slate, and other natural stone surfaces, always use a product specifically tested for stone paving rather than a generic concrete cleaner.
• Concrete and patio cleaner: For concrete slabs and imprinted concrete, our Path & Patio Cleaner and Multi-Surface Cleaner both deliver strong results on biological staining and general grime.
• Patio slab cleaner for porcelain: Porcelain paving is less porous than natural stone but still susceptible to black spot and algae. Our Black Spot Remover is suitable for porcelain surfaces.
• Sandstone patio cleaner: Similar considerations to Indian sandstone apply to other sandstone varieties. Dilution guidance on the product page should always be followed for natural stone.
• Patio brick cleaner and brick and patio cleaner: For mixed surfaces combining brick edging with paving, our range handles both in the same application.

Pet Safe and Eco-Friendly Patio Cleaner Options

One of the most frequently asked questions we receive is whether our patio cleaners are safe to use around pets. We always recommend allowing treated surfaces to dry fully and rinse thoroughly before allowing pets back onto the area.

If you need specific guidance on a product for a dog-friendly patio cleaner or pet safe patio cleaner application, contact our team directly and we'll advise on the most appropriate product and application method for your situation.

For customers looking for an eco-friendly patio cleaner, we'd encourage you to get in touch to discuss the options in our range and their environmental profile. We can advise on dilution rates and application practices that minimise impact on surrounding garden areas.

Professional Patio Cleaner: For Trade and Large Area Cleaning

Our GK Pro 5Ltr is the professional patio cleaner in our range, formulated for commercial patio cleaner applications and large-scale maintenance work. Professional cleaning and restoration companies, landscapers, property managers, and grounds workers use it for driveways and patio surfaces where volume, consistency, and performance matter.

It's the strongest patio cleaner in our range and is marked for professional use only. If you're a contractor or trade buyer, this is the product to reach for.

For smaller domestic jobs, the GK Path & Patio Cleaner is the best patio cleaner for most standard cleaning tasks, covering up to a generous area per 5-litre bottle and working effectively as both a patio cleaner spray and leave solution or a treat-and-rinse application depending on the staining type.

For long-term protection after cleaning, consider sealing your patio with GK Invisible Stone Sealer, which preserves the natural appearance of the paving while protecting against future staining and biological growth.
