Just picked up a Dagger Baja the other day (last one was made in 2001). It has a few dark stains - some rubbed out under a hose. Still lots of dark splotches though, any suggestions on what to do next? Safe to use brushes? abrasives? advice?
If it’s just grime in the scratches, a strong jet of water will often get it out. Even if it’s just a sprayer at the do-it-yourself car wash.
Nylon bristle brushes and a light bleach solution might also help.
