What type of equipment are we talking about here, I wonder. Just the stuff on your website?
I ask because it really all depends on two things:-
1) The type of
crud involved
2) The level of cleaning required
- disinfection
- thorough general cleaning
- a "quick wipe over" ...
etc.Myself, I use "whatever it takes" ... but have a preference for the "common or garden" varieties of cleaning products (you know, the type available at the local shops or hardware store). Or better still, a box of "Alco-wipes"
borrowed from the nurses. It works out cheaper that way.
And, of course, in general there's a lot for be said for good old "warm soapy water"!

Meanwhile, I would have thought that IPA would have been a bit too
severe for your type of kit. You would probably get better results using *Tesco's "anti-bacterial wipes" followed by a whiff of Mr.Sheen, I should imagine.
But here's a question for you:- what about the BP cuffs? How do you deal with those?
