FORGET OXALIC ACID......IVE GOT A BETTER ONE FOR YA!!!!!!!!!!!!!!

[munners]

Ive run out of oxalic acid and i had pair of forks that i needed to run through the process. My Mrs told me to try HP BROWN SAUCE.


I put it all over the rusty area and left over night.

Just came downstairs and run the unsharp edge of a knife over the area and it came off like butter from a knife. Just came off and it was as rusty as fook!

Give it ago. A much cheaper, quicker and easier way in my opinion and i love a bit of acid! ..................................and brown sause!

ketchup does the same thing as its the vinegar in it

I wonder if it's just HP that does the job? I've been boycotting it since they stopped making it in Aston - I might have to review my stance...

Vinegar, is cheaper than brown sauce  and it's the vinegar that does the stripping of the rust. 

[daz bmx it!]

What about Jam?

so oxalic acid works. acetic acid works, does carbonic acid work? what about weak sulphuric or hydrochloric acid? maybe lactic acid? acid house? the wife's acid tongue? d-lysergic acid diethylamide? malic acid? fumeric acid?  i think it's time for some tests.
oxalic acid is expensive and not on the shelf at B&Q. I am going to begin the experiment later with acetic acid(vinegar) and muriatic/hydrochloric acid(b&q brick acid which i happen to have a 5ltr thing of) to see what happens to a random piece of rusty steel i just happen to have.

i will post results when i have some.
please don't run off and put your 401's in brick acid.

just had a quick go with brick acid and a small paint brush. seems to work fine. will try a soak next weekend. it's nasty stuff though, burns and stinks.
