I think we have too many toys. They filled up the washing machine this morning much to my surprise...or more like much to my denial. It's hard to tell exactly how many you have when they are hiding underneath the couch, the kitchen cabinets, the bed, the covers, in other rooms, and of course outside under the shrubs. You tend to forget how many you have already when you are in the store and your dog has a sudden urge to grab a toy from the display and walk around with it in his mouth. You think "this is the one! this is the best toy in the world that he will do anything for." So you buy it. Again and again and again until you end up a carpet of squeekers that you have to step over to get out the door.
We definitely have too many so into the wash they went this morning on a cold cycle with a little detergent, and I ran them through twice just to make sure they were clean. I do put them in the dryer, but I keep it on low and check every 10-15 minutes to make sure the squeekers aren't melting. Any thick rubber toys went into the dishwasher with no detergent, but I just read about these techniques from apartment therapy that use more organic solutions.
A solution of one cup of vinegar and one cup of water in a bucket also does a nice job of disinfecting rubber toys. If you have ropes a spin in the dishwasher with no detergent works along with a minute in the microwave to kill of any additional germs. I also found a post on how to clean baby toys with natural solutions that could be adapted for your dog toys.
