I am using and caring for a set of wooden chairs (hand-carved backs) belonging to a family member.
I need to add new felt pads to the feet of most of these, as some have had old ones fall off (the remaining pads now crushed, means all must be changed on a chair).
Last year I did this. However, some of the pads fell off as there was old adhesive and debris that prevented the new pads from adhering properly.
Today I tried sanding with 400 grain paper, but the adhesive on some of the feet is just too thick. I was thinking about something like Goo-Gone (citrus based) or Murphy's Oil Soap. However, these are very nice chairs with a lovely dark-red-brown color and shiny finish (don't know what kind of wood), and I don't want to change the color of the 'ankles' or risk a droplet running down the side that might burn away the darkness in a line on one of the legs after only seconds. I've searched a couple forums, but thought I'd expand my .SE network membership here.
The only thing I've found is that some people caution against using Murphy's on wood floors, and some advise it.

If the glue is really thick, it'll take a lot of remover and work to remove. 400 grit paper is much too fine to remove adhesive. Use something closer to 100 grit sandpaper. Use a sanding block so it doesn't cut into the leg edges, and be careful to match the angle of leg end so you are just removing adhesive, not wood. In particular, do not allow the paper to cut wood in a direction that could cause the wood to splinter outwards. This is unlikely a problem as long as you are not too aggressive, because the wood is probably hardwood and not prone to splintering. If the paper gums up with glue, change to fresh paper.
Even taking your time and being careful, this will be much faster than chemical removers. As soon as you see you are starting to cut into wood, then switch to chemical remover to get the rest. Depending on the new adhesive, if there is any, you may need to seal any raw wood to provide for maximum adhesion.
The nail on pads work well, but they are more visible, so not always suitable.
