The MAF is clean if it works properly. MENU#4a shows the air-flow readings before and after using an AST Retreiver that can show live-data. That's about the best way (and easiest) that I know.

If he used a silicone product . . . you NEED to find out what was used . . . and if so,
make sure you throughly remove all of the silicone before cleaning (or replacing) the MAF otherwise the new one will be contaminated again.
When I did that PLUS I used K&N filters (MAF was also oil contaminated), I literally took the complete air management system apart and cleaned it. . . . even the INLET tubes! Don't forget them.
So I ditched my K&Ns and 'scrubbed' the MAF and cleaned the air-system . . the proof of a suceesful 'job' was on my last fillup . . just under 16mpg city. Doesn't sound like much but that's the best it's been in a couple of years . . . even with the 'big-tires' (MENU#32).
