Keeping your vinyl records clean and in good condition is important. It of course improves the sound quality obtained from the discs, but it also protects your cartridge and stylus tip (diamond) and allows for a longer life.
Felt brushes and other types of special brushes for vinyl are good. However, these should only be used when your record is 'clean', otherwise you are simply brushing the accumulated dirt and dust further into the record grooves.
The best procedure for new or used records is as follows -
1 - Clean the record with the Loricraft machine. Even if your record is 'new', clean it, because there will surely be traces of release agent on the record from the factory manufacture.
2 - Re-new the interior record sleeve (and exterior if required). This avoids putting your clean record back into a dirty or dusty old sleeve. If possible use anti-static sleeves such as NAGAOKA type etc.
3 - Now you can use the anti-static felt record brush (or similar type) each time you play your clean records, to lightly remove any foreign material and keep the record in top condition.
