Silly Squishy! that was only when I used oil based paint. I think the krud kutter or Oops would work best and of course I always have my handy dandy little wire brush to clean the base of the brush.
If you can't finish painting a project and can't wash your brush or roller, just slip it into a plastic bag (I use plastic shopping bags) and twist it as closed as you can get it to squish out all the air....next day they are still soft and ready to go again.
