I am not sure that there are too many to share but perhaps I will learn something new so thought it would be worthwhile to make a topic here. I have never really found it a chore and it gives you a good opportunity to give the bike a good check over.
Since I started waxing my chains the time I spend on bike washing has tumbled. As far as tips go, that probably doesn’t count.
I guess my only secret tip is when it comes to drying. A good cloth works ok but doesn’t really get into every spot. For me, the best solution is the leaf blower I start at the saddle and work top to bottom. It gets the frame dry in a flash and awkward components too.
