Thanks for this video Geoff. I've been taking rust off garden tools before I sharpen them (I have a small sharpening business) as an added bonus for customers. WD40 and steel wool was too laborious, White Vinegar works far better than I expected but takes around 24 hours. This is exactly what I need.

tannic acid is a much better long term use converting the rust to a much more stable oxide and can be painted directly or left as a black metal like cast iron. also much much safer

[@geoffhoyle479]

Interesting, so can you wipe the rust off or does it just turn it to oxide, and how quickly does it work, thanks

[@r2dter]

@@geoffhoyle479 you'll need to wire brush most of the caked rust off, as it converts the rust to a blue passivate, doesn't loosen it up really. Phosphoric is great as an etch for aluminium though, leaves a black passivate which is a great bondable substrate for coatings or adhesives

Is that just phosphoric acid if so at what percentage? Thanks

[@geoffhoyle479]

This was 75% I think, but get the strongest you can lay your hands on

[@oscarinnriouzz188]

Where do u buy the phosphoric acid??

[@LMK1942]

Not sure if you’re in the U.S…if so Home Depot sells Klean Strip which is phosphoric acid

[@jatwangismyname900]

Hi, is the acid harmful to the touch?

[@Realm-of-Horror]

Phosphoric acid isn't as strong as others, but even so, it will give you a chemical burn if left on the skin. Always wear gloves and wash off any splashes.

[@jatwangismyname900]

@@Realm-of-Horror Okay. Thank you

[@geoffhoyle479]

I buy it from the internet, and it doesn't make much of a smell, but its always good to wear a mask for all sorts of jobs. A mask can only be a good thing.

[@johnstream9172]

man Phosphoric Acid is to convert oxide to iron phosphate, if you want just remove rust use strong muriatic - Hydrochloric acid , then clean with water an paint it with the primer

[@daveellson962]

Do you need a mask

[@XwpisONOMA]

Not if you apply it carefully BUT wear a face mask and goggles just in case.
