Camco Formaldehyde-Free 100% Biodegradable Camco 40226 TST Fresh Scent RV Toilet Treatment -- 32 oz

A calcium nitrate holding tank formula that kills odors at the source, accelerates waste and tissue breakdown, and keeps your tank level sensors reading accurately -- without harsh chemicals, formaldehyde, or overpowering smells. One 32 oz jug treats a standard 40-gallon black tank for up to 8 weeks of weekly dosing.

Odor Control That Actually Works -- Without the Chemical Smell

TST Fresh Scent uses a calcium nitrate base to introduce oxygen into your holding tank. That oxygen environment allows aerobic (good) bacteria to thrive and out-compete the anaerobic bacteria responsible for the hydrogen sulfide odors that make RV black tanks notorious. The result is real odor elimination -- not just masking -- with a light, fresh scent rather than the overpowering perfume or chemical bite of older formaldehyde-based products.

Unlike formaldehyde treatments that kill all bacteria and rely on chemical suppression, the TST formula works with your tank's biology. It also coats sensors with a thin lubricating layer that prevents waste from sticking and causing the misreadings that plague nearly every RV owner at some point.

Waste Breakdown

Rapidly digests solids and toilet tissue to prevent pyramid plugs and stubborn clogs at the tank outlet.

Sensor Cleaning

Lubricates and cleans probe sensors so your tank monitor gives accurate readings instead of perpetual "full" alerts.

Formaldehyde-Free

Safe for septic systems and approved dump stations. No formaldehyde means no disposal restrictions at most campgrounds.

All-Temperature Formula

Works in hot summer and cool fall conditions. For temps above 85 deg F, simply increase dosage by 2-4 oz to compensate.

Dosage Guide -- Getting the Most from Every Bottle

Correct dosing is the single biggest factor in treatment performance. Too little and odor control suffers; the formula is concentrated enough that a little goes a long way when used properly.

  • Standard black tank (up to 40 gallons, 7-day hold): Add 4 oz directly to the toilet bowl and flush into the tank. Follow with enough water to cover the tank bottom.
  • Larger tanks, longer holds, or temps above 85 deg F: Add an extra 2-4 oz as needed per the conditions.
  • Portable/cassette toilets: Add 2 oz to the holding tank, then add water to cover the bottom of the tank.
  • Grey water tanks: Add 2 oz through the sink drain and flush with running water for approximately 30 seconds.
Best Practice -- Weekly Tank Flushing: Empty and flush your waste tanks at least once a week for best results, regardless of how full the tank reads. Regular flushing removes residual solids before they can build up and gives the treatment a clean environment to work in.

Where This Treatment Can Be Used

TST Fresh Scent is versatile enough to handle every liquid waste situation in an RV or marine setup:

  • Standard RV black water holding tanks
  • Portable and cassette-style toilets (Thetford, Dometic porta-potti types)
  • RV grey water tanks (sink and shower drain tanks)
  • Marine holding tanks
Shelf Life: Unopened, TST Fresh Scent has a shelf life of 4-5 years -- so buying in bulk makes practical sense for regular RV users. Once opened, use within 2-3 years and store in a location that stays above freezing.
Storage and Maintenance Tips:
  • Store above 32 deg F (0 deg C) -- freezing will degrade the formula.
  • Keep the cap tightly closed between uses to preserve potency.
  • Add the dose to the bowl first, then flush, so the treatment reaches the tank mixed with water rather than sitting concentrated at the inlet.
  • Pair with a tank rinse wand flush every few dump cycles for cleaner sensors and tank walls.
Compatibility Note: Do NOT mix TST Fresh Scent with any holding tank treatment that contains formaldehyde. The two chemistries are incompatible and will reduce the effectiveness of both products. If switching from a formaldehyde product, thoroughly flush and rinse the tank before starting TST.
Also Consider: Camco also offers TST in drop-in pods, larger 64 oz jugs, and a Citrus Scent variant. If you prefer a non-scented treatment, look at Camco TST Ultra-Concentrated or Unique RV Digest-It for enzyme-based alternatives.

Important Information -- Read Before Use
  • Do NOT mix with formaldehyde-based holding tank treatments. Flush and rinse tank completely before switching from formaldehyde products.
  • Do NOT store in freezing temperatures (at or below 32 deg F / 0 deg C). Freezing will damage the formula.
  • For tanks held longer than 7 days, or in ambient temps above 85 deg F, increase the dose by 2-4 oz or odor control will be reduced.
  • Always add treatment to the toilet bowl first and flush with water -- do not pour directly into the tank inlet.
  • Flush and empty waste tanks at least weekly for best treatment results and sensor accuracy, regardless of indicated tank level.
  • Keep out of reach of children. In case of eye or skin contact, rinse thoroughly with water.
