It’s a pity I’ve not got any projects on the go at the moment that involve de rusting or I’d give it a go to compare it with phosphoric acid.

Good thing about this process, along with the electrolytic process, unlike using an acid it doesnt affect uncorroded or non- rusty steel

How do you find the smell D ?

I used some on a engine cowling in the barn at the farm , came back a week later and the entire building reeked :shock: Worked brilliantly though .

I am watching with interest as although I love to blast most things if this is any good it maybe handy for more delicate pieces

A week in the molasses and all the rust gone along with the paint even from under the bent over teeth tabs,hasn't touched the grease on the bsa bits but is dealing to the paint and rust slowly.Takes a bit of effort to remove sludge etc maybe a waterblast before an acid etch would be the way to make it a little easier but has worked ok.Grills back together and primed but a little weld required where one or two tabs broke off the teeth while bending them back over

Hi Déjà Vu .. Newbie at this forum, but if you run out of molasses, try Coca Cola. I use old flat leftovers to derust old tools. Derusts and comes out a nice black colour.

Welcome Gleno.
Problem with using acids are they indiscriminately eat good metal along with rust,I normally set up an electolytic bath, just being lazy .I do use phosphoric as a protective etch at the end of the rust removal process which along with carbonic acid is the active acidic ingredient of cola.

Good to have you back.
Got A SWB Series 3 finished, since you were away.

Some of us are lurking in the shadows just keeping an eye on things.
Has it been eight years... I remember you commenting on my first post and I still haven't made that trek or even gotten my Fergie up to scratch yet.
