Camco 64 oz / Treats 40 Gallons 100% Biodegradable Camco 40256 TST Grey Water Odor Control -- 64 oz

Keep your RV grey water system smelling clean and flowing freely. Camco TST Grey Water Odor Control breaks down grease deposits in holding tanks, sink drains, and shower lines while neutralizing the odors that build up over time -- all with a fresh lemon scent and a formula that is safe for the environment.

Stop Grey Tank Odors Before They Start

Grey water tanks are often overlooked compared to black tanks, but they develop their own stubborn odor and grease problems fast -- especially in warm weather or during extended trips. Food residue, soap scum, and cooking grease coat drain lines and tank walls, creating the conditions for foul smells that work their way back into your living space.

Camco TST Grey Water Odor Control tackles the problem at the source. Its liquid formula is designed specifically for grey water systems -- not just holding tanks, but the sink and shower drain lines that feed them. A single 4 oz dose per 40 gallons of tank capacity is all it takes to keep things fresh between dump station visits.

Grease and Buildup Removal

Actively breaks down and dissolves grease deposits along drain lines and tank walls so they flush clean at the dump station.

Odor Elimination

Neutralizes foul grey water odors rather than masking them -- leaves a fresh lemon scent throughout the drain system.

Simple Dosing

Use just 4 oz per 40-gallon tank. The 64 oz bottle delivers up to 16 treatments -- enough for a full season of weekend trips.

Biodegradable Formula

100% biodegradable and environmentally safe -- suitable for use at campgrounds and dump stations that enforce eco-friendly chemical requirements.

How and Where to Use It

Pour the appropriate dose directly down any sink or shower drain that feeds your grey water holding tank. The formula works through the drain lines on its way to the tank, treating buildup along the entire path. Repeat each time you empty your grey tank or top up as needed during extended stays.

  • Pour into kitchen sink, bathroom sink, or shower drain -- no need to access the tank directly
  • Use 4 oz per 40 gallons of grey tank capacity; adjust dose proportionally for smaller or larger tanks
  • Apply after dumping the tank so the fresh treatment works during your next fill cycle
  • Safe for use in all standard RV grey water holding tanks, PVC drain lines, and ABS fittings
Works the Whole System -- Unlike tablet or drop-in treatments that only treat the tank itself, TST Grey Water Odor Control in liquid form coats and cleans the drain lines, P-traps, and tank inlet as it travels down, addressing the buildup that causes persistent odors before it ever reaches the tank.

Ideal Applications

  • Class A, B, and C motorhomes
  • Fifth wheels and travel trailers with grey water holding tanks
  • Toy haulers with kitchen and bath grey systems
  • Park models and seasonal campsite RVs where grey tanks sit longer between dumps
  • Marine and boat galley grey water systems
Shipping Note: This product contains liquid chemical concentrate and cannot be shipped by air. Ground shipping only. Orders to Alaska, Hawaii, and international destinations may not be eligible for shipment.
Maintenance Tip: In hot weather or during full-time RV living, increase treatment frequency or dosage slightly. Grey tanks on full-timers with heavy kitchen use tend to accumulate grease faster -- a monthly flush with extra TST Grey Water treatment helps prevent stubborn wall coating that resists standard dumping.
