[R-390] Cleaning Modules

[keller family]

I have had very good results using plain old 90% rubbing alcohol that I got at Sam's club.  It cleans all the stainless and aluminum surfaces very well just using a rag, and you can brush it into cracks and such to flush out gunk.  The best thing is that you don't have to rinse it.  The last thing I used it on was an extremely dirty SP-600, and it came out looking almost new.
