I recently bought new liquid dishwasher detergent. I buy a large jug of Cascade Complete at BJ’s. I noticed when I started using the new jug that the dishes, while clean, felt like they had a film on them. I remembered noticing that previously, but it had been a while.
Then it dawned on me that maybe it happens when I first start using a new jug of dishwasher detergent. I decided to try something. I shook the jug well before adding the detergent to the dishwasher.
Guess what? The dishes didn’t have that filmy feeling.
We shake so many other things before using them, why shouldn’t we have to shake dishwasher detergent? The need for shaking might vary depending on the type of detergent. My rinse aid dispense is broken which is why I use the “Complete” variety. It could be that’s where the problem lies.
