Keeping your RV bathroom clean, fresh and functioning properly doesn’t need to be complicated. Thetford’s range of toilet care additives is designed to work together, with each product playing a specific role across your system.

Use this guide alongside the infographic below to understand what goes where, and why it matters.

Flush Water Tank
Additives like Aqua Rinse help keep your flush water fresh while improving the effectiveness of each flush. They also leave a light, pleasant fragrance and help prevent limescale build-up in the system.

Toilet Bowl & Plastic Surfaces
Dedicated cleaners are formulated to be tough on dirt but safe on the lightweight plastics commonly used in caravan and motorhome bathrooms. Regular use helps maintain hygiene without damaging seals or surfaces.

Waste Holding Tank – Regular Use
This is where Thetford additives really make a difference. Products like Aqua Kem Blue, Aqua Kem Green, and sachets:

• Break down waste efficiently
• Reduce gas build-up and odours
• Help keep tanks easier to empty

Choosing between blue and green often comes down to preference, with green options offering a more environmentally conscious formulation.

Waste Holding Tank – Periodical Use
Tank cleaners are designed for a deeper clean. Used occasionally, they help remove stubborn deposits and keep your system performing as it should over time.

Grey Water Tank
Grey water systems can develop unpleasant smells if left untreated. Regular use of a grey water additive helps control odours and keeps things fresh between cleans.

Seals & Maintenance
A silicone spray helps protect and maintain rubber seals, extending their lifespan and ensuring your toilet continues to operate smoothly.

Using the right product in the right place not only improves hygiene and comfort, but also helps extend the life of your RV’s toilet system.
