Well if you are anything like me your KitchenAid stand mixer is going strong but the coating on the aluminum paddle and dough hook is long gone. I was tired of getting grey aluminum oxide streaks in my cookies, so I decided to do something about it. I would put a fresh powder coating on them.
Step 1: Tools/Needs
To be fixed
Sad Oxidized Aluminum Paddle Or Dough HooK
Powder Coating Gun With Power Supply
Powder Coating Powder (in any color of your choosing)
Gloves (for getting things in and out of the oven)
Well Ventilated paint Cabinet
I was doing this at the Techshop
in S.F. and they had all the tools I needed.
Step 2: Set The Uber Oven
Look at your powder as different colors need different temperatures. My powder recommends 400°F(204.44C). Since the oven is going to take quite awhile to get up to temperature. The first thing to do is fire the oven up. I set it to 425°F(218.33°C). I set it to higher than the recommended temperature to account for some of the temperature loss that will happen when opening the oven to place everything in.
Step 3: Cleaning
Now that the oven is heating up. It is time for a deep clean. To start I used the sand blaster to clean all the oxidation off the dough hook/paddle*. It made a world of difference (Take a look at before and after picture). From the sandblaster it was time to rinse the parts off in the sink. Once the dough hook/paddle are washed it is important not to touch them with your hands because the oils from your fingers will show though on the final finish. So while you are washing insert the wire hooks though the top where the connect the dough hook/paddle to your mixer**. Then touching just the wire hooks transfer them into the oven to dry.
*I could not get any pictures though the scratched up protective film sorry.
