Patio Blast 5% Concentrate Patio Cleaner 5L - B&Q

While the product is biodegradable, it's advisable to protect nearby plants by covering them or rinsing them thoroughly after application. Keep pets away from the treated area until it has dried completely and any residue has been washed away by rain.

This is a 5% concentrate and requires dilution with water before application. Please refer to the product packaging for specific dilution instructions.

This product works over time. Allow several days to weeks for the green growth, algae, or mould to break down and be washed away by natural weathering. Reapplication may be necessary for very stubborn or established growth.

Ensure the correct dilution ratio for the specific surface and type of growth is used. For extremely tough or old growth, a second application after a few weeks might be required. Always test on a small area first.

This may indicate over-application or insufficient dilution. Natural rainfall should eventually wash away light residue. For persistent residue, rinse the area with water after the product has had sufficient time to work.
