So what's the best way to get pants clean? I've noticed I still have some black splotches when getting my clothes out of the dryer today.
Most of the 'damage' is maneuvering the bike in & out of the building. Not from riding itself.
So what's the best way to get my pants clean again?
Well, don't use greasy stuff on the chain would be the best way

This is my winter bike in the depth of winter

Wax based lubricants are way cleaner.
You could also look into
gaiters.
These short ones might even do the trick.
That said, the way to get the grease off clothing if you have to is to use Carbona Stain Devils. There's one for
motor oil and lubricants. Treat the area and put them in the wash. They work very well.
