Hello Anna, I don't know where are you from and what kind of problem with limescale do you have-do you want to remove limscale from surfaces (in this case acid helps) or if you want to get rid of hard water problems from your house (and in this case I would be good to have some kind of softener; the best one is for a whole house like for example an
electronic descaler ; or just any kind of softener that isn't so expensive).
