1 week here, give or take a day
Triple 4" felt setup ( same area as 1 x 7" )
I have 2 sets in rotation
Turn inside out, rinse, into washer on gentle and warm water with a cup of bleach
2nd wash water only
Turn right side out and wash 2 more times
Stand up on ring to dry
Maybe I use a lot of water, but they're clean
