I have a big plastic bin that all of the liquids go into - wait, two bins. There is probably spilled oil at the bottom of it and a bunch of stuff that should be tossed out, but none of it gets on anything else. I should probably clean it up and organize it better - one of these days.
Helmets and boots go on a plastic shelf unit or another metal shelf unit depending on which is most handy when putting them away. Riding gear will have a separate place to hang one of these days, but for now that stuff gets piled either on the bikes or on top of some boxes in my motorcycle area.
This is what it looked like the first day it was ready for motorcycles to be parked in the area. Not quite as neat now, after months of use.
