Re: Acid pickle renoving rust?
You definitely should NOT mix any acid with the yellow chromate....with one caveat. I notice you're in the UK, and our UK distributor supplies his own chrome bearing chemicals because it's very hard to ship them from the USA to him. That being said, he may have a slightly different formula for mixing stuff, and also using it. Please check with him.
A 20-30% acid:water ratio will work for rust removal and removing old zinc plate. This information is in the manual, under Acid Pickles.
