Walex Citra-Pak RV Toilet Treatment Drop-Ins

Walex Citra-Pak are water-soluble drop-in tabs that deodorize and help break down waste and paper in RV, marine, and portable holding tanks with a bright citrus scent.

Whether you're on a weekend camping trip, cruising the coastline, or living full-time in an RV, managing odors and preventing clogs in your black tank is essential. Citra-Pak packs a convenient, mess-free tab into every load so you can maintain tank performance, preserve seals and valves, and enjoy a fresher cabin without pouring liquids or measuring chemicals.

How do these tabs make tank maintenance easier?

Each tablet dissolves quickly on contact with water and begins working immediately to soften toilet paper and loosen waste, reducing buildup that can cause sensor errors and blockages. Because they’re solid and pre-portioned, there’s no pouring, splashing, or guesswork — just drop one in and go.

• Pre-measured, water-soluble tabs for simple one-step use
• Reduces paper and waste accumulation to cut down on clogs
• Helps maintain sensor accuracy and valve operation

Will these work with my RV, boat, or portable cassette toilet?

Citra-Pak is formulated for a wide range of holding tanks, from small portable toilets to larger RV and marine black tanks. The product is compatible with typical campsite and septic systems and is designed to be campground friendly when used as directed.

• Suitable for tanks roughly 2.5 to 40 gallons in capacity
• Safe for most portable cassette, RV, and marine toilet systems
• Non-staining color and no liquid spills to manage

How noticeable is the citrus fragrance and will it mask odors?

The citrus scent is formulated to freshen the area without overpowering the cabin. It complements the deodorizing action by neutralizing odors at their source rather than only covering them, creating a cleaner-smelling environment during travel and storage.

• Subtle citrus fragrance that neutralizes common holding tank smells
• Leaves no oily residues or stains on tank surfaces
• Designed to be pleasant in small, enclosed living spaces

How often should I use these tabs and what size pack is ideal?

Frequency depends on your usage and tank size, but many RVers and boat owners drop one tab after each significant use or every few days for light use. The 30-pack tub provides a month or more of supply for typical weekend or weekly trips and is convenient for storing onboard.

• One tab per flush or per water-fill event is a common approach
• 30-tab tub is a practical supply for regular weekend trips
• Compact container stores easily in galley or utility compartments

Who is this for: Citra-Pak tabs are a good fit for RVers, boat owners, and campers who want a hassle-free, pre-measured way to control holding tank odors and minimize paper buildup without handling liquids. If you value simple maintenance, a fresh-smelling interior, and products that are campground- and septic-system considerate, this citrus-scent 30-pack from Walex provides a portable, American-made option to keep your onboard sanitation running smoothly.
