So I had to clean on old, dusty breadboard to finish my current project. I"ve been doing some demolition at the house, and the board was covered in a think coating of dust. I could only think to rinse it in the kitchen, but now I'm worried that water will be trapped in the contacts, and rust them. So, I'm going to bake it out on the oven. I have it set to about 100 degrees F. Hope that doesn't melt it. I'll post later how this went.
