i soak my pads in warm water with a touch of woolite. ring them in the soapy water a few times, ring out the soapy water and soak again in a bucket of clean plain warm water, ring out & soak a few times then run water over them while ringing them out. I air dry them and it usually only takes a day to completely dry out. because they're foam i dont dry them in direct sunlight.
I know some are in a colder climate (im in So Cal) and the air drying may not work. but then again you keep the house pretty warm so it may be best drying them out on a kitchen counter or something.
Oh, after the final rinse I put the pad in the middle of a folded up terry cotton towel and step on it, that really get the last bit of water out.
I've never dried my pads by putting them back on the PC. but then again I only use my pads maybe once every three months or so......... i dont do this as a business. I don't need the pads the next day.
good luck
