Hi guys, cleaning up a set of buddy bar valve covers. Any advice on best way to do it? Simple stuff and buff to get the fins to shine? Aluminium polish?
Cheers

I am currently cleaning an intake using WD-40.  The intake was black when I started from years and years of grease and gunk.  I let it soak in a bucket and then use a soft bristle brush to scrub off the gunk.  It is working well, but slow.   Although it isn't tampering with the original finish.   There may be other forms of cleaning as well that I don't know about.

Wire wheel cleaner . I use Eagle one brand . I am not sure if available down under or the equivalent. Scrub with a hard bristle plastic brush and rinse . If real greasy you may have to start out with lacquer thinner or carb cleaner and move on to the wire wheel cleaner . Be sure to do in well ventilated area . all these  products produce fumes and the lacquer or carb cleaner are highly flammable.  You might have to do this 2 or 3 times with the wheel cleaner and rinse procedure depending on how bad they were to begin with .  You will have to go back in and go over the fins with a aluminum polish like Mothers or Semi Chrome to shine them up. I hope this helps. Chug a Lug

Be careful on wheel cleaners for non-protective (no coating) aluminum items.  They do work well to get rid of the white corrosion but as they are acid based, the surface needs to be neutralized as soon as it is rinsed.  Some cleaners come with a two part cleaner and neutralizer.  If not, use a water base solution of baking soda, to prevent smutting (blackening) and extra pitting.  Even the dawn soap rinse works.  Before any acid cleaner is used, all grease or oild has to be removed either with a detergent rinse or solvent (brake or carb cleaner). 

Do not do any heavy chemical  treatment with the aluminum parts attached to the engine.

The results are very nice when done properly.   Cool

I was planning what Bob said, I got "eagle one wheel and tyre cleaner" in an orange bottle which is non acid based and as going to use that followed by mothers aliminium polish on the fins?

Sound reasonable and safe?

Safe ?Yes I think so because it is so mild.  I hesitate to comment on if it will work well because that is not the product I use for the aluminum intake ,valve cover etc. cleaning. I typically use that product for cleaning grime from around painted areas because it is so mild and will not dull weaker spray can paint.  I use the Eagle One "wire wheel cleaner" not the Eagle One "wheel and tire cleaner". They are two completely different products and formulas.  The acid in the wash is what cleans out the pores and bleaches the stained aluminum back .  I have used the acid version for years with no problems of neutralizing etc. etc. If that was a big problem don't you think there would be the same issue of neutralizing when used on wheels?  Wink.  It is after all a wheel cleaning product. You have to be careful but it is not battery acid your using .  Roll Eyes  I was only relating what has worked for me over and over again. Others comfort level may be different.

Trent,

Once you get them cleaned to your satisfaction you can use "Autosol" to polish the fins.
