"Wash" pistons?

I just got my motor back from the shop, on the bottom end they fit the wrist pins, honed and bored the block and balanced the crank. When I was picking my stuff up the guy who did the work asked who was building the motor. I replied I would be, it was my first build and that I had good backup in friends and on some web boards. He said two things that I'm not sure how to act on though.
1. Wash my pistons and rods.
2. Clean out my crank.
In reference to #2 he was pointing to the little ball bearings on the knife edge side of the crank. How does one go about cleaning in there, and how do you wash your pistons?

They didn't do any assembly on the bottom end, just bored and honed the block, checked piston clearance, wristpin clearance, and polished and balanced the crank. They did a competition build on the head but didn't assemble any of the rotating assembly.
Small bits on undesirable things, could be dust, sand, metal filings etc etc
I like to imagine they look like "superhatch"s avatar under a microscope
your pistons should be clean if they are new. if they arent, clean with a soft nylon brush and something fairly mild like mineral spirits
I loled.
Washing the pistons in hot,soapy water as a final step is a good idea. As far as the crank goes, it has more places for filings/abrasive bits/gunk to hide. You want to flush it, brush it, blow it out until you're sure it's spotless
Then do it again!
Like the old proverb says:
Cleanliness is next to impossible
Almost pissed my pants!!
