peter t Posted March 25, 2019 Share Posted March 25, 2019 Hi looking for ideas on treating engine aluminium parts that have that white powder oxidation on them from siting tooo long. Have just bought a car that has been in storage for a couple of years and all the parts are covered in this white powdered shit. eg water pump, rocker cover etc. Quote Link to comment Share on other sites More sharing options...

peter t Posted March 25, 2019 Author Share Posted March 25, 2019 Thanks mate but didn't want to go to this extreme . might give it a coat of degreaser or WD40 and see how that goes. Quote Link to comment Share on other sites More sharing options...
gilltech Posted March 25, 2019 Share Posted March 25, 2019 Nothing hi-tech about cleaning oxidized aluminium alloy - hot soapy water and lots of elbow grease, any scouring pads or brushes used must be very soft and gentle or you'll end up scratching the metal. Can also add some vinegar to the water as that can help. I've found WD40 quite useful in keeping parts from oxidizing again, but you have to reapply it down the track as it tends to evaporate over time. Degreaser doesn't seem to do anything much other than degrease - you need to physically remove the oxidation. My 2c worth anyway. peter t 1 Quote Link to comment Share on other sites More sharing options...
AndBir Posted March 25, 2019 Share Posted March 25, 2019 if you have some cloth polishing wheels (to use on a drill) then maybe some of this :https://www.supercheapauto.com.au/p/autosol-autosol-aluminium-polish---75ml/280137.html peter t 1 Quote Link to comment Share on other sites More sharing options...
72240Z Posted March 25, 2019 Share Posted March 25, 2019 WD40 is what I use. Spray it on and wipe it with a rag. peter t 1 Quote Link to comment Share on other sites More sharing options...
