I have inadvertently found the best……brush cleaner!

Dr. Bronner’s Pure-Castile Liquid Soap. It’s cheap and effective enough to clean foundation, cream eyeshadow & gel eyeliner brushes AND it’s totally natural – proven by this pic of my son and his cousins using it to wash their hair in Lake Winnipesaukee…we were given a bottle by my American cousins as there were 14 of us staying in a house with only one bathroom so the kids had to wash in the lake!  The bottle also says you can use it to wash veg, do the dishes, wash the dog and even brush your teeth with it!

TIP: only wet the bristles and don’t leave them to soak as it weakens the connection with the handle. Blot dry and lay flat to dry fully. Try to do it every 2 weeks.
