These purbloc microfiber hand towels are machine washable and dryer safe, and will last hundreds of washings. Just make sure that you wash separate from other fabric types without bleach or fabric softener. Your all-purpose purbloc cleaning towels will last longer if you dry them on a low heat setting. Excessive heat can melt the fibers diminishing their almost magical cleaning ability
These all-purpose towels are not color fast, so make sure that you wash darker colors separate from lighter colors.
