    Degreasing and protecting my nuts

    Now I finally have the engine out I have started to degrease everything. It's going OK but I have hit a snag with the alloy components. I was using general stuff from Supercheap and it has left some black (I assume oil) marking behind. I have read a lot of threads but was wondering what people would recommend.
    Secondly, after cleaning do I need to protect the different components such as nuts/washers, bare metal and alloy bits.

    Hi

    I have been washing alloy components etc. with a combination of CT18, elbow grease and a pressure washer. The CT18 doesn't leave any marks. Not sure how you can remove the stains your wash has left behind.

    I have been cleaning nuts, bolts, washers etc. with a wire brush on the bench grinder and then giving them a coat of penetrol. Penetrol is an anti rust control agent and seems to work pretty well. Others on here whose vehicles are actually finished may be able to vouch for the longevity of this product better than me!!

    Cheers, Martin

    i have also been using the same method as martin with the bare metal parts on the car being brushed in penetrol (you can get it from buntings)

    as for cleaning the aluminium parts i have used an acid bath wash (hydrochloric acid and water) again you can get this from bunnings, just follow the instructions on the bottle.

    cheers

    Vinegar

    Thanks for that guys.
    I went and got myself a grinder today ready for some serious cleaning this weekend. The bloke in the shop suggested I use vinegar on the aluminium, any thoughts?

    vinegar? thats new to me so not sure if it will work or not.

    if you do go down the road of acid bathing the aluminium parts be sure to wash the parts with plenty of fresh water, any acid left behind will continue to eat the aluminium.

    I also agree with Martin and Josh and after cleaning nuts and bolts etc a spray with Penetrol and allow to dry gives great protection and it creeps in every where completely. Also can be painted over providing excellent adhesion . If your careful enough oven cleaner will clean aluminum also just keep it off your skin .

    The spray can is really good and easy to use as soon as you've cleaned a bolt nut or whatever simply give a liberal coat and put it aside to dry but a word of caution when wet and allowed to dry they will tend to stick together try to lay them out separately . If say I'm cleaning a hand full of nuts bolts and washers I use a plastic takeaway container give them all a good spray and come back to it thoughout the day and give it a shake to move them a round as it settles.Hope this helps...and Bunnings has the spray also.
