I've been using it sparingly these last couple of weeks ... it seems reasonably benign.

All the usual stuff ... plastic infusion pumps of various make, model and vintage. smile

Of course RS Anti-Static Foam Cleaner (or even the Maplin clone) really deserves an honourable mention. Just as long as you spread it about, and then let it sit for a while, before wiping away the sorry mess.

If you don't inspect ... don't expect.
