Short answer is that you will destroy lung tissue. Not sure if you mean HCl in aqueous solution or HCl gas. In the latter case, whether or not it is fatal will depend on how much you inhale, but you wonât need much. It will also harm the nose and throat.

Peelaway 7 Paint Remover is a suitable for use on all woods with more modern paint or varnish on. Both of these products are a paste like product that you leave on for 24/48 hours (depending on what the test area shows) and then peel off.
Step 2. Pour 2 cups of the paint remover into a plastic container or paint tray. Resist the temptation to add more. Applying the remover a little bit at a time allows you to apply and remove it before it dries on the wall and makes the paint much harder to remove. Working in small sections also limits the amount of time you are exposed to the noxious fumes.
