A bit of pre-ride prep works well:
The night before, if you can be so organised and already have to bike cleaned, spray a hefty load of WD40 (heaven forbid!) or similar stuff, onto a rag/sponge. Liberally wipe this all over the bits that get mostly covered in goop.
Obviuosly, keep it clear of bits that need to be sticky: brake pads/rotors, shifters, levers, grips…
It’ll dry off and leave a nice non-stick film.
Then post ride a gentle hosing will remove most of the gunk, no need for seal busting pressure washers, wierd chemicals and elbow grease.
