We recommend that you vacuum around and underneath the treadmill on a monthly basis. Your treadmill will also look better much longer if you wipe the sweat off after each workout. A soft sponge or towel dampened moistened with water is best for the finish, but if necessary a mild, diluted dish soap can be used on the tough spots (use only non - phosphate cleaner.) Never use any cleaning agents on the walking deck. You can wipe down the exposed edges of the deck with a dry towel to remove the grime but do not clean the portion covered by the walking belt.
