@emrofsemanon , I have been doing this since the age of four. My first record was a Howdy Doody song book compilation. I still sign one of the songs to myself once in a while. I have been through all stages of record care from complete destruction (by modern standards) within 10 plays ( remember those ceramic cartridges that track at 5 grams) to records that seem immortal. I have gone through all stages of record care from doing absolutely nothing through the Discwasher/Zerostat days on into conductive sweep arms, a Spin Clean and now a Clearaudio Double Matrix.
As you can tell if you look at my woodworking skill I am an anal perfectionist. You have to be to produce work like that, goes with the territory.
If your jackets are clean and not a depository for dust (you always have to change them) and you brush any incidental dust off the record before or during and after play. Assuming you are not buying used records and you cartridge is appropriately set up you do not need to go any farther unless you live in a horrendous environment with cigarette smoke, cooking fumes or other pollution.
What people seen in their dirty water is predominantly surface dust that could easily have been removed by other means.
Having said all this since I have been using the Double Matrix general hygiene around the turntable has been better. My sweep arm hardly ever picks up anything and no dust collects on the mat or table itself which is nice. Am I improving the life span of my records? I do not think so. Is it worth $6500? Absolutely not. Is it worth $3000? I do not think so. I also always play with my dust cover down. I will NEVER buy a turntable without a dust cover. I consider them mandatory.
As I have said on numerous occasions with good record handling skills, clean anti static sleeves, a dust cover, a pollution free environment and a $30.00 conductive sweep arm, assuming you are not buying used records, you can get away just fine.
