I own a dishwasher. He's called Gareth :D
Ok so i do not own an actual dishwasher so this is one i can not personally try. Saving money is saving money though right? and anything which is made chemical free is fantastic in my books.
I come across these DIY dishwasher tablets over at Popsugar while searching for some scents for homemade toilet fizzes. Like with an homemade product, you could personalize them using your own scents, or even mix and match them have a little bit of a lucky dip when you go to use one.
