Jig Man Posted October 20, 2012 Report Share Posted October 20, 2012 After my cups set around unused for a while they get oily both on the inside and the outside of the cups. I can't for the life of me understand why? If one of you know please pass the info along. Also, should I be doing something to them other than taking the plastisol out after each use?

Wipe 'em out w/ a paper towel before re-use! They are a P.I.A. for sure. I use them only sparingly for specific,small mixes. They're an accident waiting to happen if you fill them over 50%.

Jig Man Posted October 20, 2012 Author Report Share Posted October 20, 2012 I guess you misunderstood my post. I don't want to know how to wipe then down after they get slick. I want to know if there is a way to keep them from getting oily in the first place. Quote Link to comment Share on other sites More sharing options...

bobv Posted October 21, 2012 Report Share Posted October 21, 2012 It appears this is a common issue with silicon goods. Searching around the net lots of cooks ask the same question but no one has an answer. Quote Link to comment Share on other sites More sharing options...
Cami Posted October 22, 2012 Report Share Posted October 22, 2012 I worked in a rubber/silicon factory for automotive parts for a while: inside silicon raw material there are several kind of "oils", after the injection inside the mold, the part can release some of these "oils"; when you will'not see more grease traces, it means that the item is dried, but it isn't a good thing. I'm using the Pop Ware silicone colapsible measuring cup, it's great with its plastic handle inside the microwave oven for my little batches: I have already saw the same effect ... doesn't matter, you have only to clean it before using.

mark poulson Posted October 23, 2012 Report Share Posted October 23, 2012 (edited) I've used Nor Por cups for more than a year so far and had no problems. I assumed the oil was a residue of the heated plastic. Whatever it is, it doesn't affect the next batch.
