Clean canisters of bacteria, lime and dust


In most cases, canisters are used as water reservoirs, for example during camping. Plastic models can be cleaned well with some aids. Bacteria, lime and dust are easy to remove. As a general rule, if poisonous substances have previously been stored in the canister, it is no longer suitable for drinking water storage.

When in doubt, never use it for drinking

For health and safety reasons, it is always important when cleaning a canister that in case of doubt a use as drinking water container is omitted. If the pollution comes from "normal" sources such as lime and dust, a food-safe cleaning is easily feasible.

For bacterial removal and disinfection some home remedies are well suited. Successful cleaning always requires complete drying out. Hot water can increase the cleaning effect, but should not have a temperature over sixty degrees Celsius. Boiling water attacks many plastics and can in the worst case lead to the dissolution of plasticizers.

Avoid mechanical action

From the often quoted cleaning tip, rice or other bulk materials to use to dissolve dried and encrusted soiling in the canister should be waived. The "abrasive" effect creates grooves and grooves in the canister, which form an ideal condition for the emergence of bacterial re-contamination.

Methods you can use to clean canisters

Shaking partial filling

Fill up about two-thirds of your canister with any type of cleaning water mixture. For heavy soiling, reduce the amount to about half.

exposure time

A decisive criterion for effectiveness of the cleaning is the exposure time. Twelve to 24 hours are a reasonable amount of time after vigorous repeated shaking.

water temperature

Use hot water with a temperature of about sixty degrees Celsius. Boiling water cools by one degree per minute.

citric acid

Better than acetic acid is the use of citric acid. You can use the pure juice of lemons or the citrus juice available for cooking and baking. Mix about one tablespoon of lemon juice per liter of water.

denture cleaners

Dissolve a denture cleaner tablet in the water for about five liters.

Disinfecting tablets (Micropur)

At the camping retailer, you will receive disinfectant tablets such as Micropur. They are actually used to clean drinking water, but are also suitable for cleaning.

Tips & Tricks

Do not use detergents that are not food safe. Dishwashing detergent works, but you should already avoid cleaning tabs for dishwashers to prevent them from reaching the required effective temperature in the canister.
