Footwear is designed to get dirty. That's why Timberland created their Dry Cleaning Kit, which includes a nylon brush and cleaner bar to safely remove dried dirt and erase stains from suede and nubuck leathers.
For use on nubuck, suede or canvas
Test on a small inconspicuous area before applying full application
Use the brush to remove loose or dried dirt
To remove stains, rub the cleaner bar lightly back and forth over the affected area and then use the brush to remove the residue
