Where can I source caustic soda? aka sodium hydroxide, sosa caustica.
Before I begin my search, I thought I'd throw it about here.
Possibly drain cleaner, I'll start at Mercadona, then ferrateria Hondura, then saavedra.
Can anyone clarify if said shops stock it, or similar.
Motives; I'm not going to kill anyone. It's an alternative to curing olives.
Sosa caustica. Most of the ferriterias sell it in 1kg bags of flakes.
thanks. didn't think it would be so easy.
Easy to get. I got some in the Chinese shop at El Mattoral on my last trip. Something like 500 grams for about 2.50â,¬ or so
Yes, they sell it in Mercadona too, and in Spar, Atlántico Centre!
Read an article in El Pais this evening about olives that included a comment about the people avoiding a repeat of the caustic soda method!
