Dust mops are available in a number of styles to fit different applications. Twisted-loop mops offer the highest level of dust pickup, and they're also less likely to get snagged on objects and fixtures. Looped-end mops offer excellent coverage and hold up to repeated launderings without fraying. Some cut-end mops can be laundered and reused, but many are considered disposable and are not designed to be washed. Some commercial dust mops are made with antimicrobial agents that resist the growth of bacteria to help keep the mops sanitary between washings.
