Phosphoric acid from the high street?

[GHA]

Anyone know somewhere to buy some but not ebay/mail order? In a bit of a rusty rush and nearly ran out of ospho.

Intensive ceramic tile and grout cleaners can have phosphoric acid in them. Very useful for removing rust stains.

I know B and Q do not stock any that do!

Yes. With ice please.

Tried a pharmacy? Small independent one may be helpful.

I have used it neat without gloves to remove rust stains in gelcoat and black streaks and brown waterline stains in paintwork. Much cheaper than a "marine equivalent"

Brilliant, thanks. Not quite as strong as ospho but should be OK if I run out, and great for rust stains

Also at Wickes- their own brand is similar I believe.

Cheers, datasheet looks identical.

This came up trumps in a magazine review a couple of years ago, apparently it's as strong as you can get on the high street (25 % phos acid).

I've used it and it does the trick.

In Australia it is sold as "Ranex" or "Fertan"

Most motor factors sell it as a rust remover. Jenolite or equivalent.
