Hi fam!!! Someone has shared with me a super easy way to clean your permanently dirty clear palette & brushes. They will look brand new afterwards. Use "Easy-Off", the oven spray cleaner. Leave it on your palette for about 5 minutes and wipe/scape off the "Easy-Off". I always use paint thinner to clean it thoroughly. That's when the magic happens. ✨
For your paint brushes, follow the same steps as above. Then twist and press the brush into a little container with some "easy-off" in it and you will see all the goo coming out. I restored ALL my brushes this way. It will do an outstanding work for your split script liner brushes. All of them came back brand new with their original bristle color!!! 🎉 Once done with the goo removal, remove most of the "easy-off" with a paper towel and clean your brushes in clean paint thinner and let dry.
Hope this is useful and helping you out to save many of your brushes. 😃
