I was washing my cycling stuff in the shower. I think I'm going to go back to the machine with a wash bag.

The main issue with the shower is that you want to wash most stuff on cold. I don't know about you, but I'm not a fan of cold showers. So really there are 3 options:
1) Hand wash in hot water (shower).
2) Machine wash cold.
3) Dedicated washing in a bucket or tub.

#3 is the easiest on clothing, but not exactly time efficient.
