Available in 1.6 oz tear-open pouches, Thetford's Tank Blaster deals with build-ups occurring in RV and marine waste tanks. Formulated as a 2-in-1 treatment, Tank Blaster's cleaners lift deposits from tank walls, while the new, super-concentrated enzymes actively attack and break down loosened deposits. The non-dusting particles contain an active enzymatic blend that blasts crud and attacks tissue, waste, and grease, cleaning the tank walls, while the special additives tackle hard water deposits on sensors. Tank Blaster is formulated as a micro-foaming solution, safe for RV and marine tanks, plumbing, seals, and surfaces.
