Components dissolved/damaged by flux cleaners?
<< < (4/8) > >>
David Hess:
A 50/50 mix of isopropyl alcohol and toluene is a common rosin flux thinner.  But I am not sure if toluene is any better than acetone as far as damaging plastics and acetone is apparently safer.

This stuff, called Cramolin Fluxoff, https://nl.rs-online.com/web/p/flux-removers/1115843/ does the job best from all solvents found.
It does not damage plastics, but it does ruin some paints. And also stickers are doomed.

Is it 30% isopropanol, 30% of "a complex mixture of hydrocarbons", 20% n-butyl acetate and some other stuff.
It's bad for you, use only in vented cabinet.

We are at least talking. Did you already use toluene? :-DD

yes you know how to talk. we know how to deal with toluene (thinner), infact i used up more than 2kg of it during these few days without respirator mask just as many times before, not to show heroism but to show i'm still around. thinner is several magnitude better at dissolving/cleaning things compared to Isopropanol alcohol (medical spirit), yes i have them and acetone too. the only thing i dont like about thinner is it leave sticky layer on the pcb when dried, but i cant find any better dissolver/cleaner. the trick is to wipe with tissue, cloth fabric or something before they dried and we get shiny as new pcb. to the OP, assume any plastic will be dissolved by the toluene (including few layers of your thin skin :P no pun intended), but not all, you have to test it yourself, but afaik its not harmfull to other electronics components. otoh, more damage have been done by people consuming alcohol (the beer, which is recommended by most) than people using toluene.

In the unlikely event that you're using polystyrene capacitors, you'd need to be extra careful with solvent usage - as they're pretty easy to damage, as I recall.

Go into a bathroom with a can of Toluene pour some on a rag, then wait minuets, you will definitely be impaired, it is akin to sniffing glue. Toluene is the ingredient in glue that makes people high, perhaps that is why some people are advocating it's use. It is a proven fact it causes Brain damage. I said a bathroom so the results would be almost immediate, In a larger enclosure not well ventilated cleaning a large board might be enough time to impair oneself. Anyone thinking of using Toluene you have been warned, there are safer and less dangerous methods to clean flux.
