Saulh:
My #1 rule is to thoroughly rinse a dirty album with warm filtered water prior to applying any type of brush/cloth/pad.
Any mystery bits on the dirty album, harder than the vinyl, will scratch the surface if brushed around.
I use a WaterPik for this as the water pressure of our kitchen sink filter is not high enough.
Once done I gently use a carbon fiber brush while running warm water from the faucet/filter, and then hit it again with the WaterPik.
I use a Groovmaster to protect the label.
Seems logical enough that I stick with it.
Afterwards I clean entirely by hand with a basic DIY wet solution and various brushes/cloths then air dry (use filtered tap water, which I find to be cleaner than the distilled water sold @ the local supers).
I have a water filter on the shower I use, but have never tried showering with an album (not certain about the effectiveness of the filter VS the one in the kitchen - plus it's just too weird).
