I use wipes to clean my pillows every day during the week, then the whole mask gets a wash in hot, soapy water and allowed to dry on Saturday.
I USED to just top my humidifier up when it needed it, washing about once a month - after reading about the young man who died from Legionnaire's cause by bacteria in a humidifier tank during a sleep study, it now only gets filled enough for a couple of nights, then washed and let dry for the day.
It helps when you can build up a stash of 'spares' like nasal pillows, masks, tubing, humidifier tank, etc. so you can use clean, dry equipment while the others are drying.
Have found that the tubing takes several days to dry, so blowing it with a hairdryer or attached to your machine will speed that up a bit.
