Had a quick look and couldn't find an appropriate thread... So... This has to be one of the coolest tips I have come across. I had heard rumours about poms cleaning the insides of their rusty and carbon caked exhausts using this system but wasn't exactly sure how it worked. But this vid shows it clearly. Cool http://www.metacafe.com/watch/456478/rust_removal_tip/ Caution with plated objects as underlying rust will react and the gas may lift the plating to escape. Apparently turning the voltage down to slow the reaction helps to reduce problems. But prolly be best prepared to re-plate.
it's been discussed in details at the gsr forum and with some pics but it's really good to see it on the video. for the "metal rod" peeps have sucessfully used an old coathanger but some had real difficulty finding the "washing soda" as aparenty it is known/sold under a different name in some areas (can't remember what it's called)
Sodium hydroxide (NaOH), also known as lye, drain cleaner and caustic soda caustic soda !or Lye !is used as a paint stripper, is highly toxic and will burn your skin off in seconds if you let it touch you http://crazymotion.net/caustic-soda-...2fOdVYjAy.html I think this is a milder version. Bicarbonate of Soda aka BAKING SODA The chemical compound for bicarbonate of soda is (NaHCO3) This guy used to sell Caustic soda (not bicarbonate of soda) http://www.trademe.co.nz/Members/Lis...member=2182249 and this guy still does http://www.sella.co.nz/store/4s4k86/top-quality-goods/
My 2 best workshop tips: 1, If it gives you trouble, get a bigger hammer 2, If in doubt about how something should look, matte black it.
