Warning, not all hot melt glue is the same.
The Clearer blue tinted hot melt tends to be much more flexible and will typically peel off cleanly. The more opaque hot melt glues often have additives that trade flexibility for more adhesion strength typically. But, many will also likely still clean up ok. That all said, stay away from the yellow tinted opaque hot melt glues, some of those have enough bonding agent that they will tear up surfaces.
These are just rules of thumb I’ve learned while developing temporary holding solutions for fireworks displays. There are thousands of different hot melt glues on the market which have many different feature. There are even permanent hot melt glues that after you use them they no longer melt.
I would bet you would want a very translucent blue tented hot melt for your job. But apply it with a thin application, because a thicker application can allow the flexibility of the glue to allow your work piece to move. If you needed a firmer option with less flexibility you can move into the opaquer glues, the bonding agents in these tend to be somewhat temperature sensitive. So if they are not cleaning up like you want at room temp, putting the piece in a freezer can have a drastic effect on clean up. This hardens the carrier and makes the glue more brittle, while also contracting the glues physical size. given it is attached to a surface that likely moves far less with chilling, the glue can almost peel itself. This is less effective with the very translucent glues as they tend to have much more elasticity.
