Graham Perry Posted September 28, 2015 Share Posted September 28, 2015 It would appear that when I competed in my most recent sprint the 12v battery split and has leaked across the engine bay oxidizing the aluminium in various far flung places. I think the cornering forces of the car on ZZR's made it run everywhere. Does anyone know the best way to tidy up and neutralise the oxidation in some awkward corners before it gets worse ? I know that the ali will be stained perminently but I am wondering what is the best way to remove the long streaky white blooms of oxidation ?Inevitably I noticed this problem for the first time when I discovered that the starter would barely turn, not having used the car for a few weeks.

robert green Posted September 29, 2015 Share Posted September 29, 2015 I had the same recently and was advised that the best course was to pour plenty of water over the affected area. This worked well and avoided adding any more chemical reactions! You do need lots of water however. Link to comment Share on other sites More sharing options...
Paul McKenzie Posted September 29, 2015 Share Posted September 29, 2015 Sodium Bicarbonate soln...as he said....you can't neutralise sulphuric acid with water, only dilute it. Link to comment Share on other sites More sharing options...
Graham Perry Posted September 30, 2015 Author Share Posted September 30, 2015 Thanks guys, I am planning a session Friday to tidy up the mess and fit a new Shield battery before my next sprint at Debden on Sunday. I got some bicarb so everything should be okay. I will revisit it over the winter as I have realised that luckily every part that appears to have damage is removeable and should take a gentle abrasive and polish to remove the worst.

Graham Perry Posted October 2, 2015 Author Share Posted October 2, 2015 Update, A nice strong mix of bicarb worked a treat and cleaned the acid bloom off nicely. Yes the ali is stained, but I know that I can tidy that up properly another time. We have just fitted the new battery and been for a spirited drive and the car is now ready for the weekend with the weather is set fair. The POBC as ever.
