Don't give up on your lucky bamboo just because the leaves turned brown. Browning is caused by too much fluoride in the water or dry air. In the winter the air becomes dry, so you need to mist your lucky bamboo occasionally. This will help with the brown leaves. As long as your stems are still firm, you should throw them away.

The cloudy smelly water can be caused by one of two things insects or algae. With both you need to clean the container and lucky bamboo as you have done. However, if you have an algae problem you might need to change containers. Algae needs light to reproduce. Clear glass containers can create a perfect environment for algae. If this is the case, find an opaque container or move your glass container farther from the light source.

With a cloudy water problem, multiple cleanings many be need. Good Luck and keep me posted.
