Dishwasher salt and rinse aid tablets

Do you need additional salt and rinse aid as well as dishwasher tablets?

According to cleaning product manufacturers, all-in-one products for dishwashers make regenerating salt and rinse aid superfluous. The rinse aid and salt functions are included in the tablet, along with other features. As a result, the customer no longer has to add salt and rinse aid. However, is the dosage in the tablet always sufficient? Thanks to extended tests in the lab and in the field, we can now give you the answer.

In areas with hard water, regenerating salt is required in dishwashers in order to soften the water in the ion exchanger, thus preventing limescale from building up. According to the information on the packaging, a perfect cleaning result can be achieved up to a water hardness of 35°fH. Tests in the lab have shown that, in some cases, it is no longer possible to guarantee a satisfactory rinsing result with additional dirt at a water hardness of over 20°fH.

What is the purpose of the rinse aid?

Using a rinse aid reduces the surface tension of the water, which significantly improves the drying effect. With tablets, the surface tension is not reduced sufficiently during rinsing and the carry-over effect (the transfer of tensides into the next wash) is inadequate. The all-in-one setting on dishwashers optimises the amount of rinse aid, resulting in a significantly better drying effect.

The bottom line
To ensure a perfect rinsing result, you should still add regenerating salt and rinse aid when using all-in-one products.

    Thank you for this blog post. So if we use all three (all-in-one tablets, dishwasher salt and rinse aid) what setting should we put “all-in-one button” on or off?
    Thank you and best regards, Ilija

      Dear Ilija. Put the “all-in-one-button” ON in order to ensure a perfect rinsing result.

    I have a water softener. Should I still add more salt?

      Dear Pauline,
      Yes, you should add salt even with a water softener. Please also check the dishwasher settings for the water hardness. With the correct setting you can save salt.
      Best regards,
      Your V-ZUG Team

    Can you please tell me who supplies dishwasher salt for my VZug

      Dear Ms Van Liempd
      Thank you for your comment.
      You can use standard regeneration salt. It does not matter whether it is fine-grained or coarse-grained.
      Best regards,
      Your V-ZUG Team

    I see two places : one for the detergent and the other for the salt. Where and how I add the rinse aid, please?


    • - 9. August 2022 9:47

      Dear Athena, thank you for your comment. You should find two compartments in your door. One is for detergent (powder or tabs) and the other compartment is for rinse aid. Look for the symbols on the lid. The symbol looks a bit like a sun and symbolises the rinse aid. If you are unsure, you will find the exact instructions and labelling for each compartment in your instruction manual. If you have any further questions, please do not hesitate to contact us. Best wishes, V-ZUG Ltd
