Some of the cards in my collection really need cleaning. Some are so bad that I don't want to handle them.

I know the best way is to gently hand wash each card and let them dry completely before repacking for storage. The problem is that I have at least 60 setups (120 decks) that need to be cleaned.

Yes these are all plastic cards, the paper ones won't get cleaned. I am not about to spend the next three years cleaning cards every night, by then I will have acquired more that need to be cleaned.
So, whats the best way to clean a massive amount of plastic cards? What will ultrasonic cleaners with a mild soapy water solution do to plastic cards? Is there any way to dry them faster than laying them out on towels and waiting hours? My wife won't be very happy with me taking over the kitchen for even a portion of my collection. She's funny about that!

Are there any intelligent suggestions??
