Follow up: Success! -I think
I could not find Odoban at Walmart. I did find 20 Mule Team Borax which was recommended on some other COTH odorific threads. I also bought TideSport as that was also recommended.
I washed the comforter with the 20 Mule Team with an extra rinse cycle. I did dry it in the dryer then hung it over the sofa to be sure it was completely dry. It was.
It smells like nothing. Perfect!
The TideSport with Febreeze I washed some athletic clothes with and it smells so heavily scented, the armpits especially :confused:. A good smell, yes, but I'm used to Arm & Hammer detergent that is much more lightly scented to where I don't smell anything when the clothes are done.
I think 20 Mule Team is the winner. Washed all the dog bedding in it; now watching and waiting to see if Joey reacts to the new detergent.
Also bought a gallon of vinegar but haven't used it yet. Will use it on the synthetic athletic clothes to try to get the B.O. out and use 20 Mule Team.
