I think I might clean mine as they will be awkward to get out once in the van. Is it worth paying for ultrasonic cleaning or does this do the job?
Mine works fine but that's not to say an improvement can't be made as they haven't been cleaned for a good while (possibly never?)
Generally you can use water and degreaser (flash works well), in an ultrasonic tank. I've also used acetone and alcohol at work before, but people are less likely to have those to hand at home.
I bought an ultrasonic tank as I had a fair few to do. Ideally you should remove the nozzles but that involves a fair bit more work and opportunity for mishaps.
I bung them in the tank for 10 mins, then give them a wipe off with some tissue. If there are still stubbourn stains then i use a plastic kitchen scourer to remove the carbon (it won't scratch the hardened steel nozzles), and then put them in the tank again for 10 mins or so until they are clean.
Lastly make sure you dry them thoroughly as you don't want them going rusty!
