I've bought Mona Lisa Pink Paint Soap to better preserve and protect my W&N 7 series brushes. It came with no instruction and I couldn't find more information on the Internet.

OK. This may be a dumb question. After completely rinsing the brush in Pink Soap, do I further rinse it in water and store it? Or, do I *dress* the brush in Pink Soap and store it?

Instructions:

Mona Lisa Pink Soap

Mona Lisa Pink Soap is designed for cleaning artist brushes. Soak bristles in Mona Lisa Pink Soap™ and work excess paint from bristles, then rinse off. After cleaning, leave a small amount in the bristles to condition, and rinse before use.

My take on this is clean with the soap , rinse then work up more lather and apply to the brush , shape the brush and allow to dry . Right before use rinse off lather then happily paint away . My brushes seems to be holding their shape and are not curling at the tip anymore since I started using the soap after wards .
One thing I forgot to add , to clean off the residual pain I use the Winsor and Newton acrylic paint cleaner before the soap . Be careful this acrylic cleaner will attack plastic don't make the mistake I did and spill it on plastic .
