Your TORUS™ bowl is robust and should last you a long time. However, we do recommend that like any drinking utensil, it should be cleaned to maintain its presentation and hygiene.
Every TORUS™ bowl should be cleaned with warm soapy water or vinegar and then thoroughly rinsed regularly. We also recommend that you use sterilizing tablets which are readily available from your supermarket, such as those used for baby bottles every few months. A global brand of sterilizer that is commonly used and readily available is Miltons. Information about Miltons sterilizing tablets is found at http://www.milton-tm.com/en/consumer/products/sterilising-tablets.
Sometimes dirt and other particles can get stuck in the entrance to the water well. We recommend using a dish-brush regularly to remove any build up.
What may cause white ‘tidal marks’ in your TORUS™ bowl?
Tap water can come from different sources in different countries and contain different chemicals and elements. For example, in many countries the water is from subterranean aquifers or even from desalination plants, whereas in other countries, drinking water is drawn directly from lakes and rivers. Different water sources and chemicals in the water can leave marks on water bowls.
We do recommend that if an owner feels that the bowl needs a clean that they use sterilizing tablets like those used for baby bottles, use soapy water, or vinegar, and then rinse well.
The materials that we use to make TORUS™ are quality food grade materials and should not discolour. It would be very unusual for plastic (Polyproplene - EP332K) to react with water. Moplen EP332K resin meets the FDA requirements in the Code of Federal Regulations in 21 CFR 177.1520 for food contact.
The cleaning processes explained above should deal with any sediment and general cleanliness.
Note: An odor may be present or small fragments of carbon may be visible when you first use your TORUS™ bowl. This will subside. It is harmless and safe for pet consumption.
