Walex RV Toilet Treatment Citra-Fresh Liquid, Citrus Scent 1 Gallon — Septic-Safe, Fast-Acting

If you spend time in an RV, boat, or using a portable cassette toilet, a reliable holding-tank treatment changes how enjoyable your trips are. Walex Citra-Fresh Liquid delivers a concentrated, septic-safe formula that begins working as soon as it hits the tank, helping reduce odors, ease waste breakdown, and keep sensors and valves operating smoothly. The citrus fragrance freshens interiors without leaving stains or harsh chemical residues.

How quickly will Citra-Fresh control odors and break down waste?

Citra-Fresh starts acting immediately on contact with tank contents: odor molecules are neutralized while enzymes and solvents accelerate paper and waste breakdown. Regular use keeps buildup minimal so tanks stay cleaner between dumpings.

• Fast-acting liquid formula for immediate odor reduction
• Helps dissolve RV toilet paper and organic waste
• Reduces buildup that can trigger sensor errors
• Continued dosing keeps tanks performing reliably

What sizes of tanks and toilets can it be used with?

Citra-Fresh is designed for a broad range of black water systems, from small 2.5-gallon cassette toilets up to larger RV and marine tanks around 40 gallons. It’s equally suitable for on-board marine systems and portable camping toilets, making it a versatile option for seasonal and year-round travelers.

• Works in cassette and portable camping toilets
• Compatible with RV black tanks and marine holding tanks
• Effective across 2.5 to about 40-gallon capacities
• Good for boondocking, extended trips, and marina use

Is Citra-Fresh safe for campground septic systems and seals?

The formula is septic system–safe and non-staining, so it won’t harm campground sanitation systems when used as directed. It’s also formulated to be gentle on valves, seals, and plumbing components while helping keep them from sticking due to waste accumulation.

• Septic-friendly ingredients that break down naturally
• Non-staining, citrus-scented for a pleasant environment
• Supports longevity of valves, seals, and plumbing parts
• Made in the USA by an established sanitation brand

How should I use the 1-gallon jug for best results?

Pour a recommended dose into the holding tank after each use or before storage, following the dosing guidelines for tank size. For ongoing odor control and sensor reliability, add treatment on a schedule—more frequent for heavy use or longer trips.

• Measure doses by tank capacity; more frequent dosing for heavy use
• Pour directly into the bowl or tank opening for quick activation
• Use before storage to prevent odors during idle periods
• One gallon supplies multiple treatments depending on tank size

Backed by a long-running sanitation brand, it’s practical for routine maintenance, seasonal preparation, and extended trips where tank performance and odor control matter most.
