Micro Mesh question

Hey guys i just bought a 16.00 detail master polishing set. It comes with 6 sheets starting with 3200 up to 12,000. My question is how do you clean the abrasive sheets? Would you use water or alcohol to clean the gunk off? By gunk i mean the sanding dust that gets clogged in the paper. Also typically how long or how many car bodies of 1/24 scale can these sheets be used on before they are wear out?

Thx for the help

Used properly, you will not need to clean them as they will never get paint buildup in them.

Here's a list of threads on using them and wetsanding:
