Hard water stain removal

You live in Melbourne, every cleaning shop sells phosphoric acid.

I live in rural QLD, there are 4 local shops I can buy phosphoric acid from and 20 online shops…

This is the definition of miss informed.

I don’t think you like being wrong! You jumped down my throat trying to sound smart and made yourself look silly!

Cc550 is hydrofluoric and not phosphorlytic acid. My bad. You may as well poor coca cola on your windows! Going back to the first post, I did mention CC550.

I’m yet to be wrong… unsure what you think your right about.

I can’t be arsed Steve, I really can’t. Good luck to you mate.
