I recently detailed a car and used my OXO Wash Brush. The under side of one of the sills must have been covered in tar as my OXO Wash Brush is now black. I allways use the two bucket method but the brush would not rinse clean. Once home I tried again to rinse the brush clean using a APC but with no luck, the brush still remains black. Im now worried of using the brush on my car incase it will damage the paintwork.
What else can I try to clean the brush and will it be ok to use even though it is black?
