removing fliud from a diff

[magman]

I spray my diffs out w/brakeclean

Or tip half out and refill with 30k.

I also use brake cleaner after I remove the internals and wipe it out with a rag. If i want the internals clean I put them is a small mesh kitchen sieve (collendar, sp?) and spray the brake cleaner thru that too. Carb cleaner works too, or nitro clean. Whatever aerosol I can find that is cheap. I am sure that simple green and water would work well, but will require drying after you wash the internals.
