Odour control for RV black tanks

Camco 41189 TST MAX Drop-INs are pre-measured packets designed for RV and marine black water tanks up to 40 gallons. Each drop-in treats waste and toilet paper while suppressing unwanted smells for up to seven days. The 15-pack suits frequent campers, boaters and anyone using portable camping toilets. The formula is safe for septic systems.

Concentrated chemistry with citrus scent

The concentrated treatment breaks down solids and tissue to help maintain sensor accuracy and prevent clogs. A single packet handles a full tank without measuring liquids. The orange fragrance masks odours during the treatment period. No dilution or mixing is required before use.

Pre-portioned packets for simple storage

Individual drop-ins eliminate spills and measuring errors common with liquid treatments. The compact 15-count bag fits easily in RV storage compartments or boat lockers. Made in the USA, the product works across boating, full-time camping, boondocking and portable toilet applications.

Questions about this item

How do I install the TST MAX Drop-INs correctly and what step do people often miss?

Drop one packet into the toilet bowl and flush; the step people miss is ensuring the black tank has enough water to dissolve the packet and activate the formula.

What maintenance or replacement will the TST MAX Drop-INs need over time?

Each packet treats up to a 40-gallon tank for up to 7 days; replace with a new Drop-IN after that period or when odors return.

What limit shows up first during sustained use of the TST MAX Drop-INs?

The 7-day odor-control window is the first limit; after that the reactive odor-eliminating technology loses effectiveness and a fresh Drop-IN is required.
