Caustic Soda

[El Tonto]

Is caustic soda readily available in Spain. I want to strip a couple of small windows which have numerous coats of paint

[Pesky Wesky]

Yes!
I know it as sosa cáustica.
You might get it in a droguería, ferretería or possibly in the cleaning stuff section in a supermarket

Agua Fuerte is a strong cleaning solution that will strip paint at a push, but be very careful as it will burn off your skin as well if you are not careful.

Yes, I think I got mine in Mercadona. I clean the drains with it every month or so, works a treat.

What's wrong with ordinary paint stripper?

Drains yes, but woodwork be very careful with the stuff as its highly reactive with skin contact. Can't you get Nitromors near you? or the careful use of a blowtorch.

Caustic Soda (Sodium Hydroxide) is a very strong alkali, very dangerous and highly corrosive, when using wear goggles and rubber gloves, if you have a spillage disperse with plenty of water. Keep away from aluminium or any other metal, it eats them.

I stripped paint using a combination of paint stripper and a Black and Decker heat gun,
