iv been doing my research on the cheapest cleaning product for my balls. I tried windex, simple green, dawn , superclean, 70% ipa and 91% ipa. of these products what worked the best for me was the 91% ipa followed by superclean simple green and dawn in that order. windex did next to nothing and 70% ipa was like water. the isopropyl 91% also happens to be the cheapest at around 2.50 per bottle. im going to do a test to see if it can dissolve lane conditioner which is mostly mineral oil per the msds, by adding mineral oil to cups filled with super clean, ipa 91%, and simple green.
