The higher the humidity, the slower mineral spirits evaporates. The drying time also depends on exactly what chemicals are in the mix. From reading about mineral spirits, I understood that it is a petroleum by-product, not a particular mix of chemicals.
Other factors are the type of adhesive, paper, and material you are using. I have tried wiping it on with a damp towel, and this removed the pattern but left adhesive that had to be removed. One of the crosses in my photo is made of hardboard, and it was coated entirely with paper with a plastic film on top. I put it on a baking sheet and soaked it with mineral sprits to get it off.
