Have you read Neil Antin’s masterpiece PACVR-3rd-Edition?
My take is that ultrasonic cleaning is the only way to get at the 1-micron dirt that hides deep in the grooves. I bought a cheap Chinese unit but it works. I use it once on all new and used records. Then they go into new Nagaoka anti-static sleeves.
Then before playing every side, I use an AudioQuest carbon fibre record brush which earths itself (through me!) when it is closed.
I have been ridiculed for the following theory on this site, but a lot of dust picked up from records turns out to be diamond dust. Stylii wear, so no prizes for guessing where the diamond dust is from. Now if you rub an excellent insulator like diamond on an excellent insulator like vinyl, stray electrons jump between them. Compared with gravity, electrostatic forces are huuuuuge - roughly 10**36 times bigger. That’s why on a dry day a few extra electrons on a comb can pick up bits of paper against the gravitational pull of all the atoms on earth.
There is anecdotal evidence of a dealer demonstrating the effect of closing a dust cover. It held so much static charge it half lifted the tone arm from the record.
So my bet is that a few stray electrons scraped off by the passing stylus attract minute charged dust particles, including those worn off the stylus. Electrostatic attraction increases as the inverse square of distance so at the micron level, it is doubly huge.
Water, treated with a recommended wetting agent, is a passable conductor. Getting it deep into the groove with an ultrasonic cleaner should discharge the static and release the dirt.
The problem with anti-static guns seems to that they alternately charge and discharge the record, and getting the record into a neutral state at the end of the process is hard.
Line shaped stylii seem to bridge over record wear caused by other shapes like elliptical and shibata.
Many old records I have bought recently have much lower surface noises than some new records - I will single out Decca (er London?) as particularly bad, especially with their flashy new folded cardboard inner with no anti-static sleeves.
