Now denture cleaner I can get. But I will have to see how long it extends their life and if it is worth the effort.
The other question I had besides cleaning heads was about the flooding problems with the CE5 after putting a new head on it (I tried 2 different heads, and they both did the same thing)
Did you remember to put the silicone/rubber cap back? When the cap is in place, there should be very little if any gaps between the wicks and the cap. Too big a gap and the liquid enters the centre tube...... too tight a fit and you'll have wicking problems.
