So, rather than rinse, wipe it down with a sponge (car wash type works well), when you do wash rinse with very low pressure (I use a garden sprayer).
Obviously you can't do much about riding in wet weather (not riding isn't a good alternative in my books), but make sure the bike doesn't sit wet afterwards.

but obviously never put any liquid in there ever...
I had this problem as well. I generally use ONR as other users have suggested, provided that my car isn't too dirty.
You may also want to look into a pesticide sprayer (the kind that you pump by hand to pressurize). I have one that holds two US gallons and it is pretty helpful for cleaning/rinsing wheels, engine bays, and undercarriages. It's also useful for spraying diluted APC or waterless wash in different applications.
It's possible to wash the entire car by hand using the two-bucket method while using the sprayer to rinse, but you essentially have to go one panel at a time and you'll probably have to refill the sprayer at least once.
 
I'm going to take a guess and assume you're in the UK? If so, here's a link to a 5L example of the sprayer I mentioned.
I've been using Muc-Off water-soluble degreaser on my bike and found that whilst brushing/scrubbing with a cloth does a reasonable job I got significantly more gunk out of the drivetrain by spraying it out with water.
I don't have a hose so use a pressure sprayer.
