I'm not going to recommend it, just because I am not sure what the outcome would be, but in my 10 years of breeding and owning my leos, I have never soaked any of mine.

If you would like to clean the urate smudge a little bit, you can soak a q-tip with warm water and dab it away, or wet your finger, paper towel or anythin not too abrasive and just gently clean her.

So you have decided not to try crickets at all?
