It is time to try to eliminate the detergent bottle from the landfill contribution we make. We use about one bottle every three weeks, which may not sound like a lot, but it still contributes to our local landfill and costs us a fair amount of money. Also, I am never really sure if the claims of ‘eco-friendly’ displayed prominantly on the bottle are true or not. So…….
I found some blogs about making dishwasher tabs (I know… we don’t have a dishwasher and are not really interested in getting one at this stage) and began to think about the differences between hand washing and dishwasher washing. Hand washing uses both chemical and mechanical means (the kind of mechanical force you apply when scrubbing that burnt pot while listening to M&M) to get the dishes clean, while a dishwasher relies on mechanical force (the pressure applied by a stream of water against the surface of the plate, while not listening to M&M) and heat to clean. So dishwasher tabs don’t have any detergent in them, they use chemicals to adjust the pH of the water to make it easier for the water and heat to do it’s job and anti-streak chemicals to make sure the dishes dry shiny and streak free. Therefore dishwasher tabs will need to be slightly different to hand washing tabs.
The dishwasher tab recipe I found is a simple combination of 1 cup washing soda, 1/2 cup citric acid, 1 tablespoon of detergent and essential oils. I decided to start with half this recipe and adjust it after testing.
I just tipped the lot into a bowl and mixed it up well.
It sort of foamed up and became light and fluffy. Apparently that is what it should do.
Then I poked a few teaspoons full into ice cube trays and pressed them down really well.
They apparently need to dry for four hours, but I found it was a lot longer than that. I left these for a day and a half.
Now for the first test! I ran some water into the sink and added a cube.
The final result; clean dishes! The cube doesn’t foam up at all, but it is easy to wash with it and the plates seem to have an extra shine on them. I will try using them for a week and see if there is any taste residue left. Maybe I won’t have to change the recipe again.
If everyone likes this option, we can go from buying one bottle of detergent every three weeks to only one a year (the recipe only uses a tablespoon per batch). I am very pleased with this project! I might go and dirty a wine glass.

Well done you! What a result. I think you need to dirty a wine glass, or even two, in the interests of continued testing. Of course 😊
Of course, I am a scientist after all (*wink, wink*). I do feel like I am making small steps in the right direction.
ewwsssshhh .. havent been here for ages & i see you are still the eco genius!!! xxx i love this .. cos yes we use a bottle a month maybe & thats to much, like you i dont trust that they’re being ‘recycled’ hmmmmm .. think might give this a go 🙂 thanking you <3
Welcome back!! I have been AWOL in the cyber world too (too much going on in the world). I am having really good results from these. I made a second batch from bicarbonate of soda instead of washing soda and they held together even better!!
And that sounds amazing . . I’ve saved you’re process and added to my do try list 😉
