Hi, it’s Vince with ShamWow. Sham Wow cloths wash, dry and polish any surface. ShamWow is like a towel, chamois and sponge all in one, except it’s extremely absorbent and can be used over and over. ShamWow towels are machine washable and bleachable, will not scratch surfaces, and will last for more than 10 years. You’ll say “Wow!” when you try ShamWow.
