Mostgirls don't know how often to wash their brushes or exactly what is the best method. I was one of these girls. I knew washing was important but I was not sure how often and with what to wash them with. Brushes that are used on a daily basis should be washed every 2 weeks.
1. Do not lay your brushes to dry on a towel. This can lead to mold buildup.
2. Do not leave your brushes to soak in cleaner, this will start to damage the wood.
3. Do not stick your brushes in a jar to dry bristle side up. The water will drip down into the handle and start to eat away at the glue holding the bristles to the handle.
