ChipQuik - A joke, or actual a useful product?

Judging from some of the answers i got, i doubt that they know what they use. Its like hit and miss with buying some stuff and it might work or might not. Seems not many care about the properties of a product and if its suitable.

Those disolve or corrode when coming into contact with acid.

I told you precisely what I use, GE clear silicone caulk. If you doubt that I know what I use then it's because you didn't bother to read what I wrote. I have used it for many years and found it to be suitable for use with electronics, as in small dabs to add support to components or a bit of insulation over high voltage terminals. I would not use it as potting compound and have never suggested that. Nor would I use it in inside a sealed enclosure without allowing it to cure first.
This is the stuff. https://www.homedepot.com/p/GE-Silicone-1-Clear-All-Purpose-Sealant-10-1-oz-2795576/317741904

I have seen corrosion on items where acetoxy (acetic) cure silicone was used, but no issue when neutral cure was used.

--- Quote from: tooki on May 13, 2023, 08:34:04 am ---Well that’s certainly not correct. Most hardware store silicone is the acetoxy cure type, which releases acetic acid (vinegar) when curing. This will cause corrosion of electronic components, so must not be used. There are “neutral cure” types at the hardware store, but that’s still no guarantee they’re compatible with electronics due to other additives.

I see people parroting this often, but I use regular acidic silicone on electronics all the time and have for decades, I've never had it cause corrosion that I can recall. YMMV but it has always worked for me.
It certainly doesn't cost "pennies per bucket" though, the last time I bought some it was over 10 bucks for the sort of tube that goes in a caulking gun.

I once tried it on bare copper, then torn it off after it cured and got green corrosion underneath.
