What to put under eggs?

[Laci7210]

I have a farm innovators still air incubator. The bottom of it is wire, which is what the eggs are on. I'm on day 19 and I want to put something between the eggs and wire for the chicks to hatch on. What should I use?
I dont want anything that will catch on fire since the incubator produces heat. I mainly want a cloth or something there but I dont know if that's safe?
Use: for the chicks to not be in the wires. And to make easy cleaning. (Eggshells might get in the space between the wire and bottom and the wire platform is not removable)
Thank you!
