So I have been using dekups for a long time and my only grip with them is the buildup of paint that gathers on the cups and such. Is there anything I can soak these cups and lids in that wont swell them all up and strip this build up of paint, clear and primer on?
You're referring to the hard plastic outer cup and retaining lid, correct? I've soaked them for days with no swelling. The flexible inner cup and lid are disposable, and will swell when soaked.
