Hmm. Lois helped Clark get rid of Kryptonite powder in my story
Further On Down the Road, but they weren't at Lois' place. It was during the tests of Superman's powers and susceptibility to the green crystal. Nigel set off a bomb at the Metropolis Museum of Natural History, and the aftermath in in chapter 19.
This was part two of a long trilogy. And I'm not sure this is what you remember. But I'm usually ready to pimp for any of my stories.
