Hello fellow members, this ancient retiree offers those who will observe the time /mixture/current limits, a very, very, easy way to remove rust on steel and iron parts. Parts required are-: 5 amp minimum power supply at 12 to 24 volts D.C. i.e. battery, or charger.
1 cupfull of household salt (normal chippy type)
2 litres (2 pints) of tapwater
mix the salt with the water and stir until totally dissolved in a plastic or glass container, NEVER metal.
Connect the negative from the battery to a large piece of lead flashing (best) or copper tube.
Connect the posotive to the part to be stripped.
Immerse the lead in the salt solution, near to the part to be stripped, WARNING! they must never ever touch each other.
Switch on p.s.u. or connect the battery and observe the rusty part. TOO long in solution = no part left.
THIS OPERATION MAY CAUSE A BUILD UP OF INFLAMMABLE OR NASTY GASES!! so keep the work area well ventilated or better still do it outside and definately do NOT smoke, cause a spark, or disconnect a battery or charger without firstly switching it OFF!,.
Its a well tried and trusted remedy if used with a bit of commonsense. If you find commonsense in short supply you would be well advised to consult your local megabucks stripper. I hold no responsibility whatsoever for these instructions other than the knowledge that I have used this method for the last 30 + years with no accidents but its up to you if you use it. Check the items every 2 minutes as this system is very aggressive and can be used for engraving/etching steel plate, so be WARNED. You should be left with metalwork that is looks as new or better than when it left the factory except for the pitting where the rust used to be. Delta bravo.
