The large 3-liter canister of the popular Solbio Original Sanitary Fluid—the most affordable way to keep your camping toilet and tanks fresh all season long. Solbio is 100% organic and plant-based, contains no chemicals, formaldehyde, or dyes, and has a pleasantly fresh scent thanks to natural essential oils of eucalyptus and mint.
4 uses in one bottle
- Waste tank: breaks down solids and prevents unpleasant odors
- Flush water tank: keeps the flush water fresh and clean
- Wastewater/greywater tank: prevents buildup and odors from the shower and sink
- Cleaning: for refreshing and cleaning the tanks
That’s why the 3-liter canister is worth it
- Significantly cheaper per liter than the small containers
- Very economical to use—one canister lasts a long time
- One product instead of three: you don’t need separate cleaners for the sewage, dishwater, and wastewater tanks
- Completely and rapidly biodegradable—also suitable for dry-separation toilets and sensitive disposal systems
