Keep some Dr Bronner's unscented castile soap on hand. Another option - unscented baby wipes. I get them from Costco, the Safeway/Albertsons stores Open Nature brand (also available at VONS, Jewel-Osco, ACME, Randalls, Tom Thumb, CARRS-Safeway, Market Street, United Supermarkets/Texas, Pavilions, Shaw's, Star, and Haggen) have no scent. Don't flush 'em though. Dude Wipes also have no scent.
