We use vinegar periodically for all the good reasons previously mentioned, but that is not our daily routine.
After every use of the head we put in a dash of Fabuloso that we had learned about when in the tropics. Besides the urine smell, if your head uses salt water
, it gets funky pretty fast in tropical weather
. Fabuloso takes care of that nicely. We also spray it on for periodic wipe downs. It comes in small spray bottles, but they also sell economical large refill sizes and it makes a good general purpose cleaner as well.
It is mild and won't hurt you skin and the lavender scented version leaves the head compartment pleasantly scented.
I have heard it also repels cockroaches.
It is also commonly available in North America.
