I agree with rinsing and drying the hoses.
The quicker you can dry anything, the less chance of anything growing in it. To quickly dry my hose loop, I blow dry it using the outlet of a small shop vacuum. That little vacuum cleaner is dedicated to this purpose and it has never seen any dust.
Here is a link to the vacuum that I use.

It dries the hoses in about 20 minutes or less.
The hose from the vacuum cleaner fits perfectly on to the regulator hose loop. There is no need for any modifications. The only thing that I did was write with a magic-marker all over the vacuum: “Not for cleaning”, “ this vacuum for clean air only”.
BTW, the concept of quickly drying, after rinsing, also applies to wetsuits and booties. I use boot driers (the kind sold for fishing waders) and in my experience, that controls any smells better than any soaking in any disinfecting chemicals or other cleaners.
