The cloth I used was barely damp. Machine had mold and mildew on it when I took it out of the case, so I wanted something a bit "stronger" to clean it. Had to pitch the case as there was no saving it, no matter what I did. Tried for months to get mold/mildew out (charcoal, dryer sheets, mild washing [damp cloth only] - nothing worked). Had broken handle and no locks, so I thought it just wasn't worth keeping. (Also, corners were so banged up the outer fabric was ripped). Bought a vintage case in pristine condition on e-bay for $30 plus $10 shipping. My girl is happy in her new house.
