How to use green remover?
For Bostik Green Remover, mix one tablet per litre of water for light staining, two for medium staining or three for heavy staining. Leave the tablets to dissolve for at least 5 minutes, mix thoroughly and apply generously with a watering can or pressure sprayer. Don’t rinse it off. Leave it to dry and allow around 1 to 5 days for the treatment to start working, then brush or wash away the loosened green staining.
