Frequently Asked Questions
Cleaning and maintenance
How do Thetford toilet additives compare to regular household cleaning products used at home when looking at their environmental impact?
A mobile toilet in your leisure vehicles is not like a regular toilet at home. A mobile toilet additive has functionalities that are not required in your toilet at home. Thetford products are technologically advanced, applying the latest developments in tailor-made ingredients for mobile toilet applications, and are specifically intended for effective treatment of toilet waste in a small, confined space. They believe in offering the best performing products for mobile and portable toilets. For that reason, they continuously develop their products to improve overall performance, whilst respecting the environment. The ingredients Thetford use in their products comply with the biodegradability requirements for detergents in the EU, and they are constantly looking for opportunities to improve product performance at all levels.
Household cleaning products are not designed to meet the requirements of a mobile toilet. Using them for a purpose for which they were not intended or treating wastewater from a mobile toilet with unsuitable products may negatively impact the environment or consumer health. So, never use a cleaning product for a purpose for which it was not designed.
In conclusion, compared to regular household cleaning products, Thetford toilet additives are a more environmentally friendly option for the treatment of waste and prevention of odour and other problems in a mobile toilet system.
What is the best maintenance for my toilet?
Empty the waste holding tank (toilet waste tank) when it is full or starts to smell (4-5 days for Thetford Blue products, 3-4 days for Thetford Green products), use Thetford Aqua Soft quick dissolving toilet paper to prevent clogging. Regularly clean the outside of the toilet with Thetford Bathroom Cleaner and clean the toilet bowl with Thetford Toilet Bowl Cleaner when necessary. Finally, clean the waste holding tank and grey water tank (tank that collects waste water from sink and shower) with Duo Tank Cleaner Concentrated 2-3 times a year to keep all moving parts inside the tank at peak operational level and to prevent odour formation during winter storage.
Why do I have to use toilet additives?
Toilet additives are important for cassette and portable toilets, as they serve several purposes. They offer a practical way to temporarily store toilet waste you would flush down the sewer system at home in a safe and practical way. They also help prevent odours, gas buildup and hard to empty waste holding tanks. Additionally, they can help to reduce the risk of blockages in the plumbing system. By using a toilet additive, you can ensure that your mobile toilet operates effectively, efficiently, and hygienically.
How can I prevent bad smells coming from the sink or shower drains in my caravan or motorhome?
To prevent nasty smells coming from the sink or shower drains in your caravan or motorhome, you can use a grey water treatment product like Thetford’s Grey Water Fresh Concentrated. This type of product is designed to prevent the buildup of grease, soap residues, and organic waste that can cause unpleasant odors in your grey water system. Simply pour the recommended amount of product into your drains and add water to keep your grey water clean and fresh. Regular use of a grey water treatment product can help maintain a clean and odour-free environment in your caravan or motorhome.
Which Thetford toilet care additives do I need?
Thetford offers Blue and Green products for the waste holding tank (your toilet tank). Aqua Kem Blue Concentrated is best for odour control and waste management in areas with access to proper waste treatment facilities. Aqua Kem Green Concentrated is good for septic tank use and is a more environmentally conscious choice. Waste-holding tank products are available in liquid, pre-dosed dry product, or liquid pod form.Use Aqua Rinse products to keep the flush water clean and to improve flushing. Aqua Rinse Concentrated is specially designed for RV’s that have a separate flush water tank and Aqua Rinse Spray is for cassette toilets that have a flushing system connected to a central water tank. Your grey water tank is the one that contains the waste water coming from your sink and shower. Grey Water Fresh Concentrated is aimed at preventing nasty smells and keeping the grey water fresh and clean. For periodical cleaning of the waste holding (toilet) and grey water tank (all waste water except toilet waste), Duo Tank Cleaner Concentrated is your best bet. Use Toilet Bowl Cleaner and Bathroom Cleaner for daily cleaning of the toilet and plastic surfaces in your vehicle.
