Dishwasher, Dishwasher, Clean us a Dish...

After the chicken nugget experiment, we had some dirty plates. So we decided to test out the new dishwasher. Living in a rented apartment, we're lucky we even have a dishwasher. It's old so we pretty much need to wash the dishes completely before we load them for a sanitizing cycle.

We always see people (on commercials mostly) loading really dirty dishes into a new dishwasher and the dishes come out sparkling. So we decided to give it a whirl.

Question: Will our dishwasher fully clean a dirty dish caked with ketchup and honey mustard?

Hypothesis: Our dishwasher will fully clean and sanitize a dish caked on with ketchup and honey mustard.

Step 1: Create dirty plates.


Step 2: Load dishwasher with said dirty plates:


Step 3: Set dishwasher to normal cycle and press start.

Step 4: Wait 120 minutes.

Step 5: Open dishwasher and analyze results.


By golly, those dishes are spotless!

Conclusion: Our dishwasher fully cleans and sanitizes a dish caked on with ketchup and honey mustard.

I can't believe your dishwasher takes 2 hours, that seems like a long time! Also, Angela suggests you microwave a slice of cheese on a plate & try your experiment again...
