So to keep this legal I need to tell you that I saw these tips on HOUSELOGIC.
I didn't know about the fabric softener trick, did you?!!
To keep paint brushes soft:
Rinse thoroughly (no soap).
Mix half a cup of fabric softener with a gallon of warm water
Swish brushes in the mixture for 10 seconds or so.
Lay them flat or hang them on a peg for overnight storage.
“That way, the bristles won’t develop a bend and will retain their usefulness for your next painting adventure,” says Artem Filikov, vice president of marketing and product development for home improvement website HomeYou.
Also, there’s no need to rinse before using. The softener actually helps distribute paint more smoothly.Sweet!
