what to use to clean running board metal

Can ne1 recommend a cleaner to clean/polish the anodized metal running board surface (without staining the rubber slats)..
Mine have a blotchy patina on them after winter..there's gotta be a product available for this type of metal...

I used distilled vinegar mixed with water to clean my matts which had a lot of salt in them. I also use it to clean the bathroom faucet and it gets the lime off. I haven't tried it on aluminum but maybe worth trying.

Have you tried Adams Polishes? Best auto detailing products on the market, hands down! Real easy to work with also.

I don't have the boards on my 2012 but had them on my 2011 as well as on other SUV's. I've used Never Dull metal polish on the running boards in past and it worked great.

Metal polishes are risky as most of the rubber slats stick through holes in the ally step. Polish residue would be extremely difficult to clean up around them. And three of those slats are actually retainers, which could be damaged by vigorous polishing.

I would prefer a liquid cleanser, perhaps vinegar would be fine, but I would like some verification that it had no ill effects first.

P21S Total Auto Wash. Place in spray bottle diluted 1:1 with water or use straight if there is tar or heavy grime. Let solution sit a minute then agitate with brush or sponge. Rinse off with strong stream of water. This keeps the boards clean and I have not had reason to polish them.

2013 ML BlueTEC
I just purchased a 2013 CPO ML 350 BTC with running boards that are discolored. It looks like the clearcoat is milky. Don't the running boards have a coating over the aluminum? I was thinking I need to treat it like paint? Did anyone have success with any of the above methods? Thank you.

How to clean aluminum

Had this problem once before with discolored anodized aluminum (non car related). Solution: WD40. Try it on a test spot.

Blotchy running boards

I had the same problem on clear coated aluminum running boards that came factory with my 2014 GL350. After some trials and tribulations - I found a good method which I gleaned off this website.

To remove / disguise the discolorations, I first used some fine metal polish which seemed to be abrasive yet safe enough to remove all the dirt and some surface oxidation;
then I followed it up by spraying WD40 liberally and rubbing it gently and then spraying again. I let the second coat of WD40 sit for about 5 minutes and then wiped all the excess off - this caused no harm to the plastic parts and made the running boards almost good as new. The WD40 also worked well to remove some tar spots and other stains.

This approach really does appear to remove/disguise the milky stains fairly well. I am glad I tried this, because I was already considering stripping the clear coat on the aluminum which probably would have been a mistake.
