I heard a rumor that jig-a-loo silicon spray melts cubes but ive also heard its awesome. If someone could tell me which cubes it hurts and which ones its good with.
it hurts all cube plastic. But Thats only if you let it pool up on the plastic is when it actually melts. I use jig a loo but i aggressively twist immediately to prevent pooling and spread it around. So just spray directly into a cube without taking it apart and and twist immediately for like 5 min.
Jigaloo fused my eastsheen 4x4 together but I use it all the time on my rubiks 4x4 and 5x5 (by just spraying it in and playing with it) without any problems. On my 3x3's I take them apart, spray with jigaloo, wait 15 minutes and wipe off, put together and it is great.
