Thetford Aqua Kem Blue is the original blue toilet fluid for the waste-holding tank of cassette and portable toilets. It's a high-strength formula that breaks down waste and controls odours, so it's the one to reach for in hot weather or on trips of five days or more.

• Breaks down waste and liquefies it for easier emptying
• Controls odours and reduces gas build-up in the tank
• Stops deposits sticking to the waste-holding tank
• Gentle on the tank, helping extend its life
• Works in high temperatures and on longer stays
• Freezes only below -17°C and works as normal once thawed

• Size: 2 litres
• Doses: approx. 13 per bottle
• For use in the waste-holding (bottom) tank
• Refresh tank every 4 to 5 days
