Onoff Posted April 9, 2018 Author Share Posted April 9, 2018 Need to derust a couple of steel wheels. And to think everything in the photo was being thrown out! My 38 year old CB pack made from a battery charger: 10ml of these per litre, so 350ml into 35 ltrs of water: And leave to ferment: Safety first: Quite why SWMBO moans...

In the States where soda blasting is big they sell the waste residue to the rail companies. My missus wants to "pour some on the patio" to test it's effectiveness at removing the green algae(?). "When I've done yer wheels luv!" Tbh when I've got the heavy stuff off I'll give them a grit blast before painting but this should save on the blasting grit. Not sure whether to knock off the balancing weights that are on there? Edited April 9, 2018 by Onoff Link to comment Share on other sites More sharing options...

Onoff Posted April 10, 2018 Author Share Posted April 10, 2018 Weights duly knocked off and back in the tank! The rust on the wheel is being transferred to the sacrificial anodes (aka bolts). Link to comment Share on other sites More sharing options...

Gloves and a mask but I did it topless which wasn't the best idea tbh with the blow back! Running out of blasting medium now. Been advised to look for J-Blast Supafine. Need somewhere close I can buy 25kg without getting stung for hefty p&p! Link to comment Share on other sites More sharing options...

Onoff Posted April 18, 2018 Author Share Posted April 18, 2018 Is there any way to gauge when my washing soda based electrolyte is exhausted? Thinking test strips? I presume it's an alkaline medium? So if it is exhasted can I just add more soda crystals and give everything a stir? Link to comment Share on other sites More sharing options...
Onoff Posted April 18, 2018 Author Share Posted April 18, 2018 The bloody dustbin leaked and CT1 wouldn't fix it! Made a new batch in a water butt. 45l water with 450ml soda crystals. The electrode "ring" could do with being set lower tbh: 24vdc psu this time at 5A and it's going berserk! 1 Link to comment Share on other sites More sharing options...

Onoff Posted April 22, 2018 Author Share Posted April 22, 2018 This is weird...the second steel wheel. The electrolysis has removed huge amounts of rust but the resultant surface is really rough, black and almost oily, stains yours hands like nothing else. I don't remember having the same amount of this stuff on the first wheel. It reminds me of when Jenolite converts iron oxide (red) to iron sulphide (black) but that I'm sure is like a hard substance. Thinking the only way to remove this black stuff is sand blasting of which I was hoping to keep to a minimum. Maybe it just needs to be left in the tank for longer?

Onoff Posted August 19, 2019 Author Share Posted August 19, 2019 (edited) Anyone used citric acid as a deruster? It "gets in places" where electrolysis, being line of sight, doesn't. Supposedly nearly as good as Bilt Hamber Deox-C which is damn good but I've run out and don't want to buy any as it's expensive. I'm going to get some citric acid from Wilko and have a go but heat in the ancient heated tank I made 35+ years back. Was meant for electroplating PCBs originally. Just found it in a clear out. Got a bearing assembly off the mower I need to loosen up. Currently pre soaking in finest McDonald's diet coke!

Jeremy Harris Posted August 20, 2019 Share Posted August 20, 2019 I've used phosphoric acid to convert rust to iron phosphate a fair bit, years ago. Works well, and isn't too expensive: https://www.ebay.co.uk/itm/Azure-Phosphoric-Acid-Descaler-Rust-Remover-30-Safe-On-Metal-Surfaces-5L/122401133301?hash=item1c7fad12f5:g:L9AAAOSwtBZbu3jY Link to comment Share on other sites More sharing options...
joe90 Posted August 20, 2019 Share Posted August 20, 2019 Timely reading!!!, I have just bought an old cylinder mower which has a fair amount of rust on various parts, I was going to wire brush with angle grinder then hammerite. Would I be better off using above acid stuff? Is there a particular way to get good results?. Link to comment Share on other sites More sharing options...
Gone West Posted August 20, 2019 Share Posted August 20, 2019 I remember in the 70s using a IIRC pink gel rust convertor based on phosphoric acid. I can't think of the name. After that I always seemed to be using copious amounts of Waxoyl. Cars always rusted away in those days. Don't see many rusty cars any more.
