I've see lots of post on polishing tunnels, bumpers, rails... But what do you use on engine and chain case. I want to do a little cleaning on a used sled I picked up and it has some obvious corrosion from road salt and such. Is there any relatively easy way to clean up things like cylinders and chain case without spending hundreds of hours? I'm not looking for a showroom mirror finish, but I'd like things to not have that white flaky crap over everything. Besides paint/powder coating, is there a way to prevent this in the future? Attached are a couple of pictures of what I'd like to clean up.
One thought I had it a mild vinegar solution and then pressure wash. Any other ideas or suggestions?

I wonder about an acid wash? I have my trailer acid washed at the local truck stop every couple of years. I think polishing would be too long and tedious for those parts. Just my two cents.
 
Try foaming coil cleaner diluted to a 1/3 water 2/3 cleaner mix. spray on with a water bottle and let sit for a minute or 2. then thoroughly rinse off all areas.

I use this on both my sled and trailer to clean up the grime and oxidation. leaves it with a nice "satin" shine/look.

Most HVAC supply stores carry this product.
Just a word of caution on its use, don't let is sit for too long, make sure to thoroughly rinse the entire area and wear gloves.

Hope that helps.

Just a guess, but that sounds harsh, especially if you get it on your plastics etc? :dunno:

Personally, first I'd just give it a good wash/scrub with hot soapy water then I'd try some WD-40 to see what happens, (then scrub and wipe up.)

Although my sleds have never been in the condition above, I have always had good luck using Citrus type cleaners as they seem to work real well for me. ;)!

(These are some before and afters of a 95 Indy Lite I picked up for my son, plus a couple of my XLT)

In the past i had a set of rails that were in mediocre shape.

I wet sanded them down, then continued to like 2000 gritt then polished to a mirror LOTS of work but came out like new.

Wet sanded from 300-2000 in small intervals. For tough spots i used the Castrol Purple Cleaner as my "wet" sand. Then went to water. Then when i was at around 2000 started the mothers polish
 
Your sleds look mint under the hood for sure. You could eat off from that XLT. Very nice.
 
I use a product called "Honey Goo" made by Kleen Flo. I had alot of corrosion starting on my sled when I bought in the States with 450 miles on it. The previous owner trailered with no salt shield. I coated the parts with the Honey goo, it goes on thin like WD40 so it penetrates but as it drys it thickens to a grease like coating. I used a small plastic brush(looks like toothbrush) with it to remove loose corrosion and work it into tight spots, then after its been on for a bit, I spray with WD40 and use a rag to remove the coating, it stopped the corrosionon magnesium and aluminium in its tracks. Always keep a can in the shop now.
