You can make your own for much cheaper; fuck capitalism.

IIRC all it is is a bit of dish soap watered down and a dash of Isopropyl alcohol. I picked up a gallon jug of Isopropyl online specifically for refilling our powerwash bottle.

yup here’s wikihow

• 4 tbsp dishsoap (concentrated since dawn brand is)
• 2 tbsp rubbing alcohol
• top the bottle with water and shake.

Edit: bonus is drastically cutting the plastic waste that comes with powerwash refills

I use BioVert, a Montréal based company for my cleaning products. And they have refill stations in grocery stores. Otherwise I just go to my local bulk store to save plastic usage.

I don’t know what you mean by spray, but maybe something here fits?

I’m not sure what dishwasher spray is, but I used the Buy Beaver app in my grocery store and found Finish dishwasher detergent was about the same price and owned by a uk company not ideal but not American.
