I spray any stains with Nature's Miracle, then just wash with a diluted laundry detergent and rinse well with the hose. I normally do this on a nice sunny day and leave it set up in the sun on my deck until completely dry.
We take ours apart and take them to the car wash. Hang them on the car mat hangers. Use the high pressure soap and then a good rinse. Comes out looking brand new and smells great!
Depending on what kind of soft crate you have I just too mind apart and threw it in the washing machine, let it air dry and it was good as new :}
I have a It's a Breeze too crate.

We have a few of the PetNation soft crates and a couple of the Noz-2-Noz crates. The covers on all will slip right off of the frames (you have to take them off when the crate is partly folded), allowing you to just throw them in the washing machine.
I put the still-wet covers back on the frames after being washed and let them air dry on a fully-assembled crate frame (as if you'd be putting a dog in them). You can always throw some color-safe bleach into the wash, too, if you're really worried about any germs. Every time I use these soft crates, I think whoever came up with the idea on these deserves a medal!
