The formulation claims powerful odor elimination for up to seven days and works effectively in tanks up to 40 gallons. The improved chemistry supports waste digestion and enhances sensor performance by reducing clogs and odors.

This 1-gallon digestant and deodorizer is designed to freshen holding tanks across RVs, boats, and portable toilets. It contains bacteria and surfactants that target clogs and organic waste at a molecular level, helping prevent backups and odors. The product is compatible with multiple tank types, including black water tanks in RVs and marine setups. Choose this option if you want a larger-volume treatment that spreads across many pump-outs and lockers. The main limitation is handling a larger quantity if you only have a small capacity tank or limited storage space.
Who it’s best for: Boaters and RV owners who prefer a versatile, large-volume solution that targets odors and solids over extended periods.
TST Blue Enzyme Toilet Treatment
This enzyme-based treatment uses a powerful enzyme complex that activates upon dilution to break down waste, toilet paper, fats, and proteins. It’s marketed as septic-safe and environmentally friendly, with up to seven days of odor control per bottle. The emphasis on biodegradable ingredients makes it appealing for eco-conscious users and those who want a formulation free from formaldehyde, pesticides, or biocides. Best for long-term campers who prioritize septic compatibility and a chemical-free odor solution. A potential drawback is the need for regular dosing to maintain odor control.

The Lavender Breeze version offers odor breakdown with a dedicated scent, helping keep holding tanks smelling fresh. It’s designed to break down waste and stubborn RV toilet paper while keeping sensors working effectively. This product is versatile for various tank sizes—from small cassette toilets to larger RV tanks—making it a flexible choice for mixed-use setups. A caution is that some users may prefer unscented options if sensitive to fragrances, and scent intensity can impact user experience in tight spaces.
