Pipe cleaners? The tube on mine is too narrow but I found a good blow through on one occasion did the trick as the blockage was caused by condensation.
I detest the thing but it is unfortunately needed.
Have you seen the interdental brushes, thicker ones might be useful, although probably not long enough.
When i said pipe cleaners,i should have said a thin piece of wire from his shed.I had not taken my cleaning kit,the one given by the hearing aid bloke,which has a little brush and two thin black wires cables or whatever the correct term is.So i went in to the shed and had a look round for the finest wire thread and like most 93 year old blokes he had one of everything you needed.Have you seen the interdental brushes, thicker ones might be useful, although probably not long enough.
that's a cracking idea.they will be shell shocked at being spoken to like that.mind you one of them might have been too egghausted to lay.It's not good enough, and I have had a stern word.
