What product should I use to remove silver spray aerosol graffiti from my garden fence previously treated with Sadolin and Cuprinol
The issue with graffiti on timber is that it is very porous and the pigments soak into the timber.
Hydron AG4 Graffiti Remover can be applied and then generally washed off with a pressure washer. It will depend how solid or soft the timber is to how much of the graffiti it can remove. It will also likely remove any Sadolin/Cuprinol product on there too.
