How do you know when it's time to throughout a bonnet? I know they get stringy but are they still absorbing as good as before they got stringy, and if not how stringy should they be before you toss them? Thanks!
You can normally use bonnets until they are pretty far gone. Some cleaning efficiency will fall off as they get older. But I would still suggest using them till they're too tired to continue being used. And then when you need more, come to Excellent Supply for the best bonnets around.
