The storage bin must be deep enough to fit a wire plate rack and still leave some room between the top of the rack and the lid.
If you are placing the container on the floor, you do not necessarily need a towel if the flooring has a rug or carpet over it.
You don’t necessarily have to use a plate drying rack. Any wire rack that holds the photo above the water while still allowing the humidity to reach it.
It’s best to start with a test photo if you’re new to the process. That way, you won’t damage a photo that means a lot to you if something goes wrong. You can use this process to uncurl any paper document. You can uncurl more than one photo at a time. Just make sure there’s a couple of inches (5-cm) between the items on the rack.
You may need to repeat this process more than once. Continue leaving the photo in the chamber for a few hours at a time until it becomes flexible enough to uncurl.
You can usually find archival blotting paper at art supply stores. The piece of blotting paper should be large enough to rest the photo. However, there should also be some overhang that you can fold over the photo to cover it later.
You can substitute parchment paper for the wax paper if you prefer.
To make the process faster, you can place a heavy item such as a brick on top of the book.
