How do you clean and refresh kraft paper folders when they get dirty?

Cleaning kraft paper folders is simple since the surface is absorbent but tough. Start by brushing off loose dust with a soft dry cloth or makeup brush. For light smudges or fingerprints, dab a barely damp cloth (water only) and blot immediately-never rub hard or soak the paper. Stubborn marks like ink can be lifted gently with a clean art eraser. If the folder has a light coating, a mild soapy solution on a microfiber cloth works, followed by quick drying with a towel. Avoid alcohol or harsh cleaners that strip natural fibers. (kraft paper folders) with corrugated cores clean best when stood upright so water doesn't pool inside. Air dry completely away from heat sources to prevent warping. For musty smells from storage, place them in a box with baking soda packets for a day or two. Refresh worn folders by slipping a fresh printed label over the old one or adding washi tape along edges for reinforcement. Regular light cleaning keeps them looking sharp for months.
