Full Product Description

The Camco 41190 (Bilingual Label) is a “one-step” sanitation solution that requires no mixing or complex preparation. It uses an advanced, biodegradable chemistry that is safe for all septic systems and environmental dump stations. Unlike older chemical treatments, TST MAX does not rely on formaldehyde; instead, it uses reactive odor-eliminating technology combined with a blend of surfactant oils that trap unwanted gasses beneath the water line.

Beyond odor control, this treatment acts as a tank conditioner. It aids in waste digestion, which helps keep the interior tank walls and sensors clean, preventing the “false full” readings often caused by debris buildup. It is suitable for use in all temperatures and weather conditions, though it is recommended to store the bottle in a climate-controlled area to prevent freezing.
