citric acid rust removal

Post by youknowturbo on Sat Dec 12, 2015 7:32 am

i was looking for way to remove rust and stumble across a vid on youtube explaining that citric acid removes rust and kills it.
so i go on ebay get the cheapest bag of citric acid and make a bath with a pyrex bole and put 5 big spoonfuls of citric acid then fill with water, stir it a bit then dip a caliper in for 24 hours, heres the results both calipers from a vw sharan that had been in the scrappy a good 10 years. make up your own mind, i wiped it over with a soft spronge and this is the results, im ganna give it another 48 hours and will post back,
i want to dip a uno next lol

think you get the idea of how good this stuff is now

nuts and bolts come out mint after 24 hours
these heavily rusted calipers took 3 x 24hours, new mix every 24 hours to bring to this state
probably one more mix and 24 hours they would be mint
which i think is amazing for the cost of about £2.00 as i still have loads of citric acid left
