Frequently Asked Questions (FAQs)
1. Does Blue Diamond toilet fluid contain formaldehyde?
Blue Diamond produce three types of toilet fluid. Our three litre toilet fluid is not a concentrated fluid and contains 10% formaldehyde, our 2 litre blue toilet fluid contains 24% toilet fluid, and so is classed as a concentrate, and our third type is a formaldehyde free formula, known as Toilet Fluid Green.
2. What is the difference between blue and green toilet chemicals?
What is the difference between Aqua Kem Blue (AKB) and Aqua Kem Green (AKG)? The purpose of both additives is the same, but the Aqua Kem Green is more environmentally conscious. Aqua Kem Green is a toilet fluid with biological action and can be safely emptied into a septic tank (Test ISO 11734).
3. Do cassette toilets use chemicals?
Unlike the blue/green toilet chemicals, pink toilet chemicals are not used in the cassette itself. A dose of pink toilet chemical is added to the flush tank for the cassette toilet. This is usually done through a small locker hatch on the outside of the caravan/motorhome just above the main cassette locker door.
4. Which chemical is used in toilet?
Many chemical toilets use a blue dye in the bowl water. In the past, disinfection was generally carried out by mixing formaldehyde, bleach, or similar chemicals with the toilet water when flushed. Modern formulations are nitrate-based and work biologically.
