Thread: What are you working on?

I have heard of it used to remove rust. But as Mike said the syrup is very corrosive.
I'd be leery to use it on gold etched blades, as it very well could remove the gold

I've used ketchup to clean the bottom of copper pans.

I don't think it would effect the gold at all but maybe it would get under the gold and release it from the base metal especially if there was some corrosion under the gold.

Well it was a thought I don't have a test blade was just curious really. Always looking to make some things easier. Thanks for the input gents.

Getting my restore block made. Should have glued end magnets first these 2 idiots were trying to pull one another out of there holes. Gonna wait for epoxy to set for sure before setting the last magnet.

Also finished this Geneva pyramid. Proud 6/8, wasn't really bad just scratches every where. Polished the God awful butterscotch scales a bit and the blade cleaned to a nice shine so I didn't bother sanding. Cleaned up well all around.

Next up the Acme Razor from Keene Cutlery Co. 5/8 nice etch, scales are bakelite and all should clean up nicely.

The active ingredient is Phosphoric acid. Dabbed onto red rust it will turn it black but too long an exposure & you will darken the steel.
Gold is unharmed IME.

Coca-Cola contains some phosphoric acid. You can use many different acids to remove rust; some are better than others. Watch the heck out for muriatic (hydrochloric) acid -- the fumes will eat any steel in your shop.

Phosphoric acid is actually a great rust converter -- it's the stuff in naval jelly. But Coke is not a good source of phosphoric acid -- it's a 0.25% solution. You can get phosphoric acid cleaners at Home Depot, like "Miracle Sealants 32 oz. Fast-Acting Phosphoric Acid Cleaner" for $11.95, and while the SDS doesn't say the concentration of phosphoric acid, it does say that the pH is 0.5 - 2.0, which is actually pretty strong acid, so I suspect there is a pretty good concentration in this stuff.

Me, I am loving the Evapo-Rust. It's pricey though. Haven't tried it on gold wash but I might -- I have a Globusmen 6/8 with nice gold wash but unfortunately some rust.

I've always found the Birchwood Casey Rust & Blue Remover works well if dabbed on the gold wash with a q-tip.
