"Pine Sol corrosive?" Topic

I placed some old painted metal Citadel and Marauder figures in pine sol and forgot about them for about a year until I found them in a container today. The paint and glue were somewhat loose but not as much as I expected. The figures also seemed to have alot of white residue, I can't tell but I fear the white may be corrosion. I will need to remove the paint and glue residue to know for certain. Has anyone experienced pine sol destroying metal figures after a long bath?

Looked up the MSDS for Pine Sol. You're basically looking at Ammonia and Benzoic Acid.

Ammonia in gas form, as opposed to liquidin from in PS, actually retads metal corrosion. Benzoic acid, the other main in PS, weakens oxide bonds in metals.

Both, however, will emulsify most paints, so they will let the oxygen dissolved in the liquid get at the metal unierneath. Your enemy there was time.

Depending on what metals are in the minis, most likely you will have pitting, were you got some corrosion, but the benzoic acid broke it down leaving a hole.

Still, there shouldn't have been a lot of corrosion in the first place, since there shouldn't have been much oxygen in the "bath".

Lead is highly resistant to corrosion.

It does form a lead-oxide patina, which is indistinguishable from the surface of the lead. After that, if exposed to carbon (like CO2 in the air), it will form a lead carbonate patina which is white, but not the "white lead" version of lead carbonate. If this is exposted to sulfur (like naturally in the air, or aided by common types of pollution), it will form a darker red-ish (colour depending on what else is around) lead sulphate.

The key bit of the patina is that it is very thin, so removing it technically removes some layer of lead from the outside of the figure (the bonded molecules), but not enough that you could notice it without some good scientific measuring instruments. In a way, the patina effectively protects the mini from further degradation. Don't remove it until you are ready to prime and paint (providing your own portective coat).

I've never had any problems with metal miniatures in Pine-Sol, but I've never left any to soak for as long as a year.

As far as I know.
