Hi, most of the plastic mixing cups I use do not clean very well after use, especially with epoxy.
If I leave the resin inside, it becomes brittle and never detaches completely. If I clean it with acetone, over time the plastic becomes dull getting the problem worse.
So do you use any strategy not to waste too many mixing cups?
I was thinking about using a realease agent but I am worried about contaminating the resin.
Also I try to look for silicone mixing cups but found nothing in the usual stores.
Ideas?

In theory but they would likely be disproportionately expensive. Also silicone has a limited lifespan with resins in them so after 15-20 pulls would start to break up or have resin stick. So I suspect in the long run it would not be any cheaper.
