Ok...you want to know what a nice garage floor looks like in Winter? Here it is ... this is not for the squeamish.

First of all...the before shots are after I vacuumed up as much mung as I could as it fell off the cars....so...the total run-off is far worse... and indeed forms a small lake on the floor at its peak. This is a couple of days later after the snow has subsided.
The after is the result of hosing the floor down, brushing with a push broom, hosing again and then going over with a string mop.
The whole proceedure took about 1/2 hour.
I've also included a photo of the brown tire stain that evil_c5 and I were discussing.
