The grids I have curve at the edges so they sit well above the bottom of the quarter half sheet pan (for air circulation maybe). They stack together in pairs.
I can put hot soapy water in the sheet pan and turn one of the grids upside down into that soapy water. After a couple hours, all cleans up fairly easily.
The problem is that I usually have more than one dirty grid and sheet pan. Not enough room on the counter for two soapy sheet pans.
So, I'm looking for a container into which will fit a couple grids and couple sheet pans.
Suggestions where to look, please?
