New routine: I replace the domes every night. I have a stock of 20 tulip domes that get rotated every 20 days. Each night the dirty domes get cleaned with dish soap and running water and placed in the drier overnight before going back into stock. My aids are ready to wear with fresh clean domes in the morning.
Aids also go in the dryer but I use HA sweat bands 100% of the time so there is never any cleaning needed of the aids themselves.
This method is far easier and less time consuming for RIC and instant dome use.
