  • My dishes come out dirty all the time, do I need a new washer?

    There could be several reasons why effectiveness has fallen, even in new machines. Check manufactures’ guidelines for best practices, don’t over-fill your machine, make sure the temperature and cycle time is appropriate, and rinse heavily stained crockery before placing in your machine. Many machines have a rinse aid drawer, keeping this topped up can positively influence the end results. Dishwashers need cleaning too and a simple cleaning regime using KNAUS™ Washing Machine and Dishwasher Cleaner can help improve performance and cleanliness of cutlery and dishes.

  • Do you need to clean your microwave?

    Microwaves (inside and out) are swarming with germs, both from leftover food bits and our own skin contact. A study led by microbiologist Charles Gerba from the University of Arizona found that the door handle on a microwave is one of the dirtiest surfaces in our kitchen.

    More bad news: The heating power of a microwave doesn’t sterilize its contents as well as you might think—a recent study published in Scientific Reports (found that microwaving a sponge actually leaves behind plenty of germs that can spread and make the sponge disgusting again. If the new food you’re microwaving is thick or an odd shape, it might cook unevenly (even with a turntable) leaving behind cold pockets for bacteria to thrive in, says microbiologist Julie Torruellas Garcia, associate professor in the Department of Biological Sciences at Nova South-eastern University. Always cover food if you’re using the microwave, it’s a lot cleaner and easier to maintain your appliance.
