There are several ways to clean something up to get it ready for paint. But here’s a way I found most effective!
A Simple Way to Clean Hardware Before Painting
After removing your hardware, put them in a sink or bucket. What ever you have around that will hold the hardware and allow you to apply an even coat of Krud Kutter.
Thoroughly spray Krud Kutter all over the hardware-front and back! Make sure every little area gets sprayed. Let it sit for 5-10 minutes.
With the Krud Kutter still on the hardware, use Dawn dish soap and a toothbrush to start scrubbing.
Use the toothbrush to scrub every part of the hardware. The Krud Kutter should have loosened up and build up and the soap and tooth brush will help remove it completely.
When finish scrubbing, rinse with warm water. Make sure any soap or cleaner is rinsed off.
Now lay out to dry! Make sure to lay out spaced apart, not one on top of another. You could lay on a towel too. It was hot day out so I laid them outside.
if drying inside, overnight should be long enough.
