how to clean old LPs


Hi , can someone help me on this :
I have hundreds of LPs , they have never been played for about 15 years , but , I put them in anti static sleeves either from Nagaoka or discwasher.
I found some to be still in good condition , but , some are looking not glossy anymore ( good vynil should look shiny isn't it )
I guess the problem lies in the bad material of the vynil? so they accumulated soft dust that make them looking dull..worse still , the sound is noisy.. and after we finished playing the dirty LP , the stylus accumulate the soft dust..
I once try clean it with Matrix cleaner from Clearaudio , but no luck..they are still dull and dirty

There are several cleaning alternatives. Many people here like using one of the multi-step cleaning fluid solutions such as Walker Audio Prelude, Audio Intelligent or Disc Doctor. Use your Matrix cleaner to vacuum away the fluid residue between steps. My preference is for the Walker Audio Prelude, but I hear reports of very good results from Audio Intelligent as well.

Steam cleaning with a small hand held steamer also has its proponents on this board. Read the many posts on this topic carefully and use care if you follow this approach.

Not as commonly discussed here is ultrasonic bath cleaning, but that requires different equipment.
Go to Wallyworld and pick up a hand held steamer with a 4" attatchment..I use a Shark Steamer..I can't imagine any cleaner ( manual or automatic ) that will remove more grunge and leave a more clean surface than Steam cleaning...I know there are guys ( and gals ) with plenty of Green to buy the Big Boy Auto cleaners,,but for a few bucks these little hand held steamers will compete with anything.........No bells and whistles but they work....
