Corrosive Caulk Question.

This is by far the strangest question I've had to ask on TFL. I needed to do some emergency window repair (old house) with some DAP clear caulk that has the notice 'may corrode some metals' on the tube.

Does anyone know if this refers to the actual contact of the caulk on metal or the fumes given off? Or is this something I shouldn't be concerned about? I had a few guns on the work bench that I planned to clean when the situation became... apparent? :o I planned to clean them regardless but am unsure if I should clean them differently at all because of this.

Luckily the storm was brief and I was able to air my room out relatively quickly. Does anyone have experience on this? Or more knowledge then I on this topic?

I was looking at this page which may or may not apply. I still have the empty tube of anyone needs more specifics.

Some of the clear caulks contain acidic acid (vinegar) which will react to metals. If used in a well ventilated area, I wouldn't expect fumes to be a problem. Once the caulk has cured, you shouldn't have problems.
 
That's correct. As far as silicone sealers goes there are many types .Some for kitchen and bathroom have a mold resistant additive. The one for delicate electronics will NOT harm circuitry but it's very expensive . I've been using silicone for many years .All kinds of applications. Just read the labels first.
 
Try the Ecclectic E-6000 series next time. That stuff is as tenacious a sealant as I've ever used. It uses dry cleaning chemicals as the solvent, not acetic acid.

For what it's worth, I've used acetic-acid based silicone right next to electronics and bare steel components and never had an issue.
 
Since you planned to clean the guns anyway, just go ahead and use your normal cleaning procedure -- if the fumes were strong enough to corrode metal at a distance, I think your lungs would also be letting you know something was wrong.

That said, discussion of the merits of different types of caulking compound is a bit off-topic here...
