Trac Ecological 1218-MC SEW CLEAN 1 GAL

I review this from the product purchased locally, this order has yet to be received from Amazon supplier.Foul odor from our boat holding tank caused us to use this product as recommended by our boatyard. It did reduce the odor and worked out. Quite expensive, if it continues to work we plan to use again.The supplier was another matter. It was ordered and said it would be a week and a few days to get into a box. Then the delivery notice from Amazon said it would arrive last Friday. It did not.In the meantime we found we could buy it from our boatyard at the same price, less tax, and from Defender Marine for $58.00 + sales tax. This was one of the few failures both in shipping and price from Amazon!

cleans clogged urinal pipes without damage. Accidentally tried muriatic acid instead once and that resulted in a big problem. Expensive but lasts a while.

I use this to open the drain on my water-less urinal when the urea crystals build up in the pipes and slow the flow. Works like a charm and melts buildup away for a clean and clear drain when nothing else seemed to work.

Works great!
