If your can is empty, you can remove the Lid/Stir and clean it using the recommended clean-up procedure listed on the product card.
Suggestions for water-base products:
1. Get a bucket of warm soapy water and spin your Lid/Stir until the bulk of the paint is dissolved. You can then give a light scrub to remove any remaining paint residue.
2. Set the wet Lid/Stir out to dry and then easily peel off the paint from the paddles.
3. Rinse under warm water and rub with your hands until paint is removed.
