Tried isopropyl alcohol vs contact cleaner on a sticky NES cartridge slot. Alcohol won by a mile.
Had this old NES that kept glitching out on the first boot. Figured it was the 72 pin connector acting up again. Read online that some people swear by contact cleaner for this. Gave it a shot with a can of CRC QD. Worked okay for like a day then the problem came back. Swapped to 91% isopropyl alcohol and a toothbrush. Scrubbed the pins, let it dry, and its been running perfect for two weeks straight now. Way cheaper too. Anyone else have better luck with one over the other?

Worked okay for like a day" that right there tells me the contact cleaner did its job but didn't fix the real issue. Alcohol's just better at cutting through the years of crust and oxidation on those old pins, no contest.

@simontorres I get what you're saying but I've had contact cleaner fix stuff for good before.
