Whoops….soda crystals in the dishwasher!

Put Soda Crystals in the Dishwasher by mistake?

If you have, don't worry, you aren't the first and you certainly won't be the last.

Dishwashers use a special granular salt to soften the water. It works via an ion-exchange process and salt doesn't actually enter the wash chamber. Here is some more information about how a dishwasher water softener works. Salt action tablets DO NOT replace the need for salt in the softener and some manufacturers may void your warranty if you don't use dishwasher salt.

It's possible to mistake your bag of dishwasher salt for your bag of Soda Crystals....so what should you do if you have filled up the reservoir with Soda Crystals instead of salt?

Adding salt to the dishwasher

How to remove Soda Crystals from the salt reservoir

  1. If you've filled the reservoir to the top you may be able to scoop a fair amount of the crystals (why not put them down the sink to help keep it fresh?).
  2. Once you've manually removed as much as you can, boil a full kettle of water and pour it into the reservoir; the hot water will dissolve the Soda Crystals and displace them in solution.
  3. Fill the reservoir with Dishwasher Salt and run an empty wash to remove the Soda Crystals residue.

Cleaning the Dishwasher

Although Soda Crystals are ideal for cleaning your washing machine, they should not be used to clean your dishwasher; for that you require White Vinegar or Citric Acid.

  1. Does this mean that soda crystals cannot be used to make dishwasher tablets? I have seen many recipes that use soda crystals. I personally have tried citric acid with bicarb and a little dish soap but it doesn’t really work. Any links to recipes for using dri pak products in the dishwasher?

    1. We don’t recommend home made dishwasher tablets/powder as they are specially formulated. Some people do make their own up and swear by them, but we are uncertain what the long terms effects would be. Bicarb and citric should almost never be used together unless you specifically want the fizzing chemical reaction. It’s just an acid and alkali reacting with each other. Our advice is as hollows:
      1. Always ensure there is dishwasher salt in the reservoir
      2. Use powder or tablets…but ‘salt action’ tabs do NOT replace the need for dishwasher salt
      3. Use rinse aid or white vinegar
      4. Clean the dishwasher routinely with citric acid or white vinegar.

  2. Am so glad to find a company that is providing good quality cleaning materials that are not a danger to this earth of ours.
    Am aware that several of your products are sold via Wilkinsons under their branding. This is great news as I’m able to purchase locally.
    Sadly, have not yet found the citric acid, liquid bicarb, soda crystals laundry boost nor the borax substitute.
    Please inform me if and where I can purchase those items.
    Many thanks and please, keep up the good work.
    Regards Veronica

    1. Hi Veronica – thank you for your kind words. Wilko do the citric acid, so you can order it for click & collect at your local store. We do hope they will eventually take the Bicarb Cream (which replaces the Liquid Bicarb). You can buy this water softening powder from Wilko which is the same product as Borax Substitute (Sodium Sesquicarbonate). Soda Crystals can be bought from most Sainsburys stores. Call 0800 636 262 to find your nearest store. More information is available on our Buy page.
