[Brian Duff]

So that thread had been Hi-Jacked. Consider it grounded and jump on this one!

Topic is something like what do you use to bust corrosion or inhibit it?

Does anyone else use Ospho for soaking rusty stainless?

"Originally Posted by RoyB
What is Ospho? Many substances have different names here in Australia. For example, beer is referred to as 'Piss" :-). Seriously! "


"I hope no one thinks I am trying to promote the stuff. I just wondered if others have used it for soaking rust stained stainless.
The below is from their website."


"When applied to rusted surfaces, it resists/retards rust in chemical change on drying to a tough, hard surface ready for priming. A paint job will last longer after an application of OSPHO because subsequent paint coating securely attaches itself so that moisture and oxygen normally do not attack the metal. OSPHO is water-thin, can cover a larger area than paint, and goes on easily. It is equally effective for exterior and interior work alike. SKYCO OSPHO: a balanced formula of Phosphoric, Dichromate, Wetting Agents and Extenders . . . compounded exclusively by the Skybryte Company since 1947 ... recommended by paint manufacturers."
