Gaianotes Acrylic Solvent T-02m 500mL

The 500mL bottle is a solid size for studio work, and it thins my water-soluble acrylics to a nice flow without breaking down the pigment. I've been using it to clean brushes between color changes and it gets them ready in a few quick swishes.

My brushes rinse out in seconds now, no more scrubbing paint out of the bristles, and the paint flows smoothly without clumping. Even after a few weeks open, it still works just as well for cleaning up dried-on messes.

The 500mL bottle lasts surprisingly long since you only need a tiny splash to get the paint flowing smoothly. It also does a great job rinsing out brushes that have started to stiffen, leaving them clean without any sticky residue.
