5 Things to Know About Cleaning Extension Cords

Wipe dry mud off with a rag If mud is caked on, knock it off with a gloved hand or dry brush. No water or cleaner needed.

Use mineral spirits or isopropyl alcohol for paint These evaporate fast and won’t harm standard rubber or vinyl insulation. Avoid acetone, lacquer thinner, or anything labeled “strong.”

Keep solvents off the prongs Solvents on metal prongs can cause corrosion or electrical issues. Wipe the cord jacket only.

Match solvent to paint type Use mineral spirits for oil-based paint and a soapy rag for water-based paint. Don’t let solvent sit on the cord for more than a few seconds.

Test a hidden spot first Most consumer extension cords handle solvents fine, but test a small area if you’re unsure. Avoid soaking the cord or scrubbing with a wire brush.
