Sully,

I'll defer to your experience using CLR, but I would be afraid of using it around aluminum components.

I would be more likely to try soap first for the oil removal and see what I had after that.

What is your experience with it around aluminum? Will it damage aluminum, and heater and radiator cores?

David,

I would not use it, however, here's a link to the CLR website, review the MSDS and the FAQ.

How would CLR work for getting rid of calcium deposits?
It's reasonably priced.

I share your caution about using clr on unplated aluminum. I used it on chrome, porcelain , glass and gel coat and it worked very well for hard water deposit removal.

I piped up about the clr and calcium without noting context.

It is stated directly in the product cautions that clr is NOT to be used on aluminum and will remove the finish from aluminum and copper.
