Let’s say you are painting your front door, and you have to wait a few hours for the first coat of paint to dry. You are planning to wash your paintbrush in the meantime, as most experts advise, but you suddenly realize that you have no solvent at hand. And you don’t have time to go out and buy the proper cleaners to wash your paintbrush. What should you do?
Don R. Simon, Jr. of Bremerton, Washington, advises using a plastic sandwich bag to keep your paintbrush fresh for hours and even days. Simply cut a small V-shaped hole on one side of the sandwich bag, about 1 ½ inches above the corner. Open the mouth of the sandwich bag widely and insert the paintbrush with the handle first towards the hole. Pull the handle through the hole until the bristles reach the opposite corner of the sandwich bag. Once the paintbrush is set, roll the plastic around the paintbrush until the seal is reached. Lock the sealing strip of the sandwich bag, and use a rubber band or tape to keep it tightly sealed. Yes, it’s as simple as that.
