ya i believe it is an abbreviation... but the bottle says CLR really big on it... so if you don't recognize it, you probably haven't seen it lol.
CLR has annoying commercials >.<
haha i live in az so i find it humorous that the best thing i've found is called "Fabuloso".
just a cleaning product. kills the odors really well. couple squirts in the base, water, swish, let sit. Then i hold the base upside down and use my garden hose and shoot water into the base for about a min. all good
also, i try to put limes/lemons in my base water as often as possible.
