Disco Antistat manual wet cleaning machine, £50. Wash a few discs at a time, I usually do 8 or 10, wash again with the machine in pure deionized water with 1 drop of photo wetting agent or rinse aid dishwasher potion. Buy the water from a decent motor factor its only a few quid for 5 litres. I have been working through my records in this way for the past 3 years or so. Results have been really good, some 40 year old discs I had pensioned off and "replaced" with CDs have been transformed, the CD doesnt get played now. I always clean new LPs too, before playing, but after a close visual scrutiny, incase they have to go back. I find that 95% of my LPs cleaned are now almost silent regarding surface noise, except of course when there is physical damage to the groove. Cleaning wont transform a damaged or poorly pressed disc that has crap imbedded in the vinyl. I have no static issues. I've used Nagaoka inner sleeves for years. I clean the stylus every now and then with an AT vibrating pad cleaner gadget that I've had for ever.
