Yes, I rinse them well, soap and water, let dry completely.

It is scented litter as well, and I think I have a pretty good sniffer, so I re-rinse and soap again of any hint of scent remains.

I bleach them if the scent is tenacious, which sometimes happens if I bought several buckets of litter (3 cats, they use it up) and they were stored for a long time.
