Removal tips for trees, sidewalks, and vehicles
Trees
Wash the tree with a garden hose. Do not use lacquer thinner or paint. You might apply mineral spirits and let it sit for five to 10 minutes, and then wash with water. Contact a nursery for other suggestions.
Sidewalks
Use a wire brush. If that doesn’t work, try lacquer thinner or pressure washing. Clean one square at a time.
Vehicles
Use a solvent-based cleaner that can be obtained from hardware or home improvement stores. Be aware that these cleaners are likely to remove the wax from your vehicle’s paint as well as the graffiti.
