My first job (at age 15) was at the Night Kitchen, a bakery near my house which needed a dishwasher.  I thought it would be easy (nice short bike ride away, extra treats when done) and not too hard to do well — much better than the idea of being a dishwasher in a restaurant.  

I have never hated sticky buns as much as I did after scrubbing muffin tins, cookie sheets, and bread pans.  And my hands never really got clean after hours of contact with dough.
 

Having a system helps – a lot.  After seeing the same muffin tins and bread pans, I figured out the best way to scrub them so they got clean.  

Understanding the workflow of the operation also is key to finding the right solution to the problem – in this case, knowing to start with the dirtiest burnt pans and soak them while cleaning the other cookie sheets later.  

Finally, learn to appreciate the labor and love that go into a product.  I can now fully understand the end-to-end process of making bread, muffins, and other goodies, and I save the dishwashing for home.
