How to use
Disinfecting the water tank: step by step
Whether it’s a motorhome, caravan or boat: you can disinfect the tank and pipes with a shock disinfection; when filling the tank, you can disinfect the drinking water using a low dosage. According to the label, the 250 ml bottle is sufficient for a shock disinfection of a 125-litre tank.
20 ml
per 10 litres of water in the tank (shock disinfection)
Leave to act for 6 to 12 hours, then empty and rinse the tank and pipes.
For normal filling, use 0.67 ml per 10 litres; for a 100-litre tank, this amounts to 6.7 ml.
Prepare the shock disinfection solution
Fill the tank completely with tap water and add 20 ml of the solution per 10 litres of water. Open all taps one after the other until water flows from the tank, then close them again. Leave the solution to work for 6 to 12 hours.
Empty and rinse
Empty the tank and pipes completely and rinse thoroughly with fresh tap water. Water used for shock disinfection is not suitable for drinking.
Drinking water during filling
To disinfect the drinking water, add 0.67 ml per 10 litres of tap water while filling and leave it to work for 20 minutes, as per the manufacturer’s instructions. Do not add another dose until at least 24 hours have passed.
Use biocidal products with care. Always read the label and product information before use. Water from a shock disinfection is not suitable for drinking.

Good to know
Why water tanks should be disinfected regularly
Whether it’s a motorhome, a boat or a holiday home: a water tank needs looking after, even if the water looks clean.
Stagnant water, warm days
Water that sits in the tank and in the pipes heats up in summer. Germs can then settle on the tank walls, in hoses and filters, and form a biofilm. Contaminated water often looks clear and has no noticeable odour.
When a shock disinfection may be advisable
This depends on the usage, duration of inactivity and condition of the system. Typical occasions include the start of the season, the end of the winter break or long periods of inactivity. Also, follow the maintenance and hygiene instructions provided by the vehicle or tank manufacturer.
Considering the whole system
The solution should reach not only the tank but also the pipework. For filters, boilers and seals, follow the instructions provided by their respective manufacturers.

Frequently asked questions about tank disinfection with CDL2go 250 ml
Empty the tank, fill it completely with tap water and add 20 ml of the solution per 10 litres of water. Open all taps one after the other until water flows from the tank, then close them again and leave the solution to work for 6 to 12 hours. Then completely empty the tank and pipes and rinse thoroughly with fresh tap water.
For shock disinfection, use 20 ml per 10 litres of water in a fully filled tank; for a 100-litre tank, this means 200 ml. According to the label, the 250 ml bottle is sufficient for a 125-litre tank. The figures for 50 to 125 litres are given in the dosage table.
This depends on the usage, duration of inactivity and condition of the system. Typical occasions include the start of the season, the end of the winter break or long periods of inactivity. Also, follow the maintenance and hygiene instructions provided by the vehicle or tank manufacturer.
Yes. During the shock disinfection, open all taps one after the other until water flows from the tank, then close them again. This ensures the solution reaches the pipes as well.
No. Water from the shock disinfection is not drinking water. After 6 to 12 hours, completely empty the tank and pipes and rinse them thoroughly with fresh tap water. Only then should you fill the tank with drinking water.
To disinfect drinking water, use 0.67 ml per 10 litres of tap water; for a 100-litre tank, this amounts to 6.7 ml. In numerical terms, this equates to an addition of approximately 0.2 mg of chlorine dioxide per litre. According to the manufacturer’s instructions, allow it to take effect for 20 minutes; do not add another dose until at least 24 hours have passed.
At the dosage described here of 0.67 ml per 10 litres, the 250 ml bottle is sufficient for around 3,700 litres; for a 100-litre tank, this equates to around 37 fillings. After a shock disinfection, correspondingly less will remain. The label states 1,875–15,000 litres; this range results from different dosages.
For filters, boilers, seals and pipes, follow the instructions provided by their respective manufacturers. Remove filters before carrying out shock disinfection if necessary.
Yes. The same procedure applies to drinking water tanks on board as in a motorhome: shock disinfection using 20 ml per 10 litres of water in the tank; for disinfecting the drinking water, use 0.67 ml per 10 litres when filling.
Upright, tightly sealed and in a cool place; once opened, keep it in the fridge. Do not leave it in a hot vehicle in summer, as heat causes chlorine dioxide to escape as a gas. Use by the date printed on the bottle.
For jerrycans and occasional dosing, CDL2go 100 ml is often sufficient. The concentration and composition are the same; you’ll also find a dosing chart there for 5 to 25 litres.
No. The chlorine dioxide is already fully dissolved; there is no need to mix it with a second component. To use it, dilute the solution with water as per the instructions.
No. The solution is not intended for ingestion or for use on humans. It is neither a medicine nor a foodstuff.
Rinse your mouth immediately, do not induce vomiting, and contact the poison control centre or seek medical advice straight away, showing them the label. Berlin Poison Control Centre: 030 19240; in the event of severe symptoms, call the emergency services on 112.
