how to clean BedRug?

What's the best way to clean a BedRug?

When I bought it (used) I vacuumed it, rinsed it with pressurized water in a wash bay, and let dry.

Nothing crazy.
But recently, I accidentally spilled coolant on it, and want to figure out how to give it a good cleaning before potentially ever having to lay on it.

I'm thinking the easiest way would be to go to a DIY car wash, and wash it. Maybe holding the sprayer slightly far away to be a bit more gentle, and brushing with soapy broom. Rinse, take home, find a place for it to air dry.

Is that the right move?
I think another option might be renting a wet/dry vac to do a carpet shampoo detailing type of thing

Had a buddy get diesel in his and that's what he used.
He did pull his out to do it but you might not have to.
