500 albums in a basement flood--worth saving?

Don't like either toothbrush (too harsh) or dish detergent (full of contaminants).

Member antinn is a first class expert on cleaning, and has contributed extensively to the thread "thumbs up for ultrasonic cleaning". His contributions alone raise the discussion above the level achieved in the 'Rushton' thread and its derivatives. 

My friends and I bought a number of records from a similar situation. They all came out fine after ultrasonic cleaning.

Thing about US cleaning is that solids just come off the surface and drop to the bottom. No damage at all.

I use a very fine product from Louisiana if I remember correctly. Vinyl Stack has a stand, motor, and spindle for use with just about anybody’s US tank. I went with an ElmaSonic tank (German) because I have several thousand records and an expensive cartridge to protect, but you can use any tank, and just about any tank is better than the next best cleaning alternative. IMO.

There are several good threads on US record cleaning here and on DIY Audio.

You can get a variety of sleeves online from many record stores. Elusive Disk is good - I prefer MOFI sleeves, for what it's worth.

Good luck! May your records stay safe!

ElmaSonic is pretty much a Mercedes product, so you might find it to be overkill. But it is among the best and easiest to use. The 80KHz option gives better cleaning and quieter operation - at a price. Tell the wife that you bought it to clean her jewelry, oh, and to use it yourself when she didn't need it.
