I had a Bringham Premium Dehumidification jar. It was a plastic container with beads. After a year or so it began to turn a bit brown. Any theories on this?KL as a rule doesn't change much but I have a few tupperadors where it has gotten a bit darker but I still use it with no issues at all. Here's the best part about KL...it's so cheap you can throw it out and put in new KL for pennies....if it makes you feel better to do that....by all means start over with fresh litter.Is it necessary to replace if it changes colors?
I chucked the beads and replaced them with kitty litter.
