So my 3x3 was getting a bit sluggish, and I bought Silicone Lube from Walmart. I applied it to my speedcube, and it turned extremely smoothly afterwards, which was nice. But what was not nice was that the paper towels, in which I used to prevent my desk from getting silicone all over it, stuck to the plastic of my cube. Now the outside is all stained and has little pieces of paper towel stuck to it, which does not look nice. If anyone could tell me how to get these stains off my cube, and possibly prevent this from happening in the future, that would be nice. Thanks.
