I agree lewm. It can't remove grunge. However, if a record is not fingerprinted and kept in a rice paper sleeve other than when being played and has the dust removed each time, inside a record jacket (or sometimes 2) inside an outer plastic sleeve inside a sealed glass cabinet door, how does it get grungy? I am meticulous in handling and storing my records. The brush magnetically removes dust I guess because of the static charges that makes the dust stick to the fibers and it sweeps larger particles and hairs. I'm sure it doesn't remove deep dirt. I've lived with the risk of a sound difference for 40 years, and I don't see it changing. There is so much difference from record to record in SQ, that it is really hard to tell as you play different records if one would need cleaning beyond the dusting before every play.
I think I bought 2 EX records and was not comfortable with them one time and brought them to my brother in-law's (not a special trip) and I cleaned them. He has some expensive VPI machine I think. It vacuums and brushes and everything. It was more time consuming than I thought, and I am wondering how he keeps track of when he cleaned which records. He doesn't even have them situated perfectly vertically as I do. Another thing to keep track of and worry about if they always look shiny and clean....
They were still EX records though. That's when I said NM or Mint (which is really new but opened and never played I guess) only if not available new.
Obviously if you are an avid buyer (or seller) of used records a RCM is a must have.
