Valterra V23128 Pure Power Blue Waste Digester
Best for RVs and boats with mixed waste streams. This fluid liquefies waste and toilet paper for easier draining and helps maintain a clean tank environment. It’s suitable for both gray and black water tanks, offering added versatility for multi-vehicle setups. Best for campers who prioritize simple maintenance and quick waste breakdown. Caution: avoid use with non-septic or problematic plumbing systems without checking compatibility.
Camco TST Blue Enzyme Toilet Treatment 41501
Best for odor control over longer trips. This enzyme-based formula activates upon dilution to break down waste, paper, fats, and proteins. It treats up to 40 gallons per 4 oz bottle and can provide odor elimination for up to a week. It’s septic-safe and formaldehyde-free, making it a responsible option for RVers and boaters. Limitation: may require consistent use to maintain odor control in very hot climates or heavy usage.
Reliance BIO-BLUE FLUID Deodorant 16 oz
Best for quick deodorizing in portable toilets and small holding tanks. This fast-acting deodorant provides a pleasant scent within minutes and includes a level indicator for easy measuring. It’s safe for all flushable portable toilets and marine systems. Use this when you want a simple, short-term odor fix between deeper tank treatments. Caution: it is a deodorizer, not a heavy-duty digester, so pair with waste-digesting products when needed for heavy waste loads.
Unique RV Digest-It Ultra Liquid
Best for routine tank treatment with strong odor control. This bio-enzymatic formula liquefies waste quickly and acts as a deodorizer, helping to prevent sludge and sensor issues. One bottle provides up to 32 treatments, making it a reliable option for travelers who want fewer mid-season purchases. Limitation: higher concentration may be overkill for very small holding tanks or single-occupant setups.
Valterra V23103 Pure Power Blue 40 oz
Best for versatile odor control with strong liquefaction. This formulation works in both black and gray tanks and is designed to handle diverse waste streams. It’s suitable for mixed-use RV setups and for travelers who want a single product that covers multiple tank configurations. Caution: verify compatibility with your specific tank material and any additives already in use to avoid interactions.

Notes on product selection
All five products target odor control and waste digestion for RVs, boats, and portable toilets. Choose based on tank size, usage frequency, and whether you need dual-tank versatility (black and gray). For heavy travel and mixed-use systems, a combined digesting-and-odor-control solution often provides the best balance. If odor is your primary concern, pair a fast-acting deodorant with a robust enzyme-based digester for best results over longer trips.
