daverclasper Posted August 15, 2021 Report Share Posted August 15, 2021 (edited) Hi. I heard that folk in the States use this method, so thought I'd give it a go and share my experience and try and encourage more "tips and tricks stuff?. I tried this on an area of wheel arch lip than the paint had flaked off on, exposing fairly engrained surface rust. Wallpaper paste and Citric acid powder are the ingredients. When the paste has thickened, add the Citric acid powder. I used about a third powder to paste, though I assume more powder would make it more effective. Applied roughly a 2mm coat and covered with cling film (though doesn't seem to dry out quickly like the bought acid gel does). Did this at tea time at the Malvern Show and removed it the next morning. Apart from some very tiny pin prick pits (another coat, or stronger solution may have helped this) It was totally clean of rust. So, from this trial it seems better than the bought ones and much cheaper. Warmer weather helps with any acid solution. Also can be used with water instead of wallpaper paste for parts that can be dipped (works well apparently). A fish tank heater helps with the heat.

daverclasper Posted August 15, 2021 Author Report Share Posted August 15, 2021 (edited) Just to add as I don't appear to have an "edit" function at the mo. Maybe worth just mixing a very small amount as a trial for ratio's, sorry to be "Nanny State", though I can have a bad habit of often mixing up too much stuff myself🤗 Edited August 15, 2021 by daverclasper Link to comment Share on other sites More sharing options...

Bfg Posted August 16, 2021 Report Share Posted August 16, 2021 Thanks Dave for the tip, better still when you followed it up by personally having tried it. ..trust me I understand how such total thread drifts, albeit not meant unkindly, can upset. If it's of any consolation.. I appreciate your post, although I'd never heard of citric-acid-powder before. Reading of its various uses I've ordered 1/2kg of today (ebay, under £4 in postage). So cheers mate Pete. Link to comment Share on other sites More sharing options...

JohnD Posted August 16, 2021 Report Share Posted August 16, 2021 Not home made, but a recent' "Which?-style" test caught my eye. Mr.Edward China has a series of videos online, about his re-commisioning of a neglected Range Rover. In this episode he's dealing with a VERY rusty fuel tank, and trials a series of rust treatments, by placing test pieces of rusty steel in them overnight. See: https://www.youtube.com/watch?v=Iu2TD3OUI3Q&ab_channel=EddChina The trial results are from 22 minutes in. He tried three "rust removers", three "rust converters", and Coke! He made no comment on the failures, but while all the converters seemed to work, it was obvious on screen that two of the removers, Jenolite and white vinegar (!) did buggar all. Coke worked, a bit, but it's a surprise that Jenolite was so useless! John Link to comment Share on other sites More sharing options...
PeteH Posted August 16, 2021 Report Share Posted August 16, 2021 Hi White Vinnegar Crystals are used/useful for many things. My most recent, was to clean and de-scale the 16/30 Heater Matrix. I have it "on hand" as it`s my go-to de-scaler for any sort of "Stainless" steel product, where some de-scalers, especially those containing Clorines can cause perferation.

Pete Here in France vinaigre blanc is the preferred descaler, comes in 5 litre 'bidons' at 14% compared to 8 for normal. Works well. French classic sites even talk about using it to clean out the cooling system. Link to comment Share on other sites More sharing options...

I use it annually, to clean/descale the water heater in my Motorhome, A tea spoon full in the kettle (1.7L) removes the hard water scale very effectively too.

Unkel Kunkel Posted August 17, 2021 Report Share Posted August 17, 2021 Citric acid in kg bags cheap via Ebay. I have used it as a solution to immerse parts rather than a paste. Works better warmed.-brewing type immersion heater. It isn’t super fast and helps to take the object out and wire- brush now and again. It is safe to use - certainly much more user- friendly than hydrochloric acid ( like brick cleaner) which can burn skin and the HCL vapour will surface rust any ferrous metal in the vicinity. or phosphoric acid works well - which is Jenolite -rather expensive ( better value for money phosphoric acid is Machine Mart’s own brand which seems very similar ) Coca Cola is disappointing.the amount of phosphoric acid in it is tiny ( which is hardly surprising, really since its drinkable !) Acetic acid - vinegar never been that impressed ;Ok for cleaning coins. Electrolysis using Washing Soda solution, sodium carbonate, and battery charger leads - Works well but it is very messy !
