CamcoTST Lemon Scent RV Grey Water Odor Control, Stops Sink Trap Odors, for Use in Drains,Sink Traps and Waste Vents + TST Orange 30 Pack Ultra-Concentrated Citrus Scent RV Toilet Treatment Drop-Ins

These work great and don't smell bad. If I had my choice, I would prefer the gray water treatment to also be orange scented instead of lemon but that is just a personal preference of scent. They do their jobs as advertised and that really is the important part. I don't understand why you would sell this as a set with 2 different scents but that would be my need for order and logic coming out.

Works great, and the individual drop-ins are handy and a lot easier than measuring and pouring. Grey tank wash also worked well.

The orange pods keep the black tank clean, and the lemon liquid helps keep the smell coming from the tanks by sitting in the P-trap as well as help with the grey tank.

Great deal

Works like it should. No odors.

Very disappointed that our product came extremely damaged. Will not be ordering again.
