CRC 05103-Case 5103 Quick Dry Electronic Cleaner, 11oz, Pack of 12

This is an excellent cleaner for electrical equipment and works well on tools too. I use it for rebuilding lithium-ion batteries to clean up circuit boards and electrical terminals. The fast drying and low reactivity with plastic parts makes it great for cleaning batteries. This product is a little spendy but well worth the price.

I use quite a bit. This works well on many things.

this stuff has so many uses. general cleaning, cleaning grease off your clothes, starting a mower like a start fluid, etc.

I use this all the time and it doesn't have an overwhelming negative smell like some of them do. I buy this stuff by the case for my farm using it for various reasons.

I've been using it for maybe 30 years. Works well, no mess, and I've yet to have it damage any material.
