In the toilets. One salt water, one fresh water.
Bought a used boat and the head was black and disgusting. Can't use bleach without damaging the head, so I tried this stuff. Put it in, let it set for 20 min and scrubbed, which did about 80% of the job. Once more did the job. The head had been sitting filthy for at least 6 months when I bought it, so I was impressed.
Stuff works great, never had a problem with it.
