What kind of glue?

I would try the Goo Gone too, I got some tile adhesive and double sided tape glue off with it. Took a couple applications of letting it sit for 15-20 minutes, rubbing it was a scratchy pad, wiping off and repeating a time or two more but it all came up.

How about putting it in the freezer. I've heard you can put gum on cloth in their and after its frozen it will chunk off.
I've also heard if someone gets gum in their hair to hold ice cubes on the hair and it will chip off.

I've heard that if you iron over aluminium foil it lifts the glue.

My big mistake was that I bought a new iron and forgot to take the protective plastic off the sole plate before plugging it in. I noticed it when it started smoking. I didn't have room in my freezer so I sat the iron in a tray of ice after it cooled down and I stopped kicking myself. Sure enough the plastic chipped right off. What little residue was left I used a magic eraser on and voila! iron was saved. I use magic eraser to periodically clean my iron if there's any accumulation of stuff on the plate.

Well, I have gotten fusible on my ironing board and by ironing a scrap to it and quickly pulling it up I managed to get most of it off. (I have no idea what a Square-n-Blocker is)

This works on a hard surface, spray on and let it set for 20 mins.

The smell is strong orange.

Adhesive remover is acetone - the same chemical in nail polish remover. The remover tends to be oily, so be careful how you use it. Acetone can dissolve some fabrics (mainly polys), so if you decide to try it, try first in a small hidden area.

Have you tried ice cubes for "freezing" the glue, then scraping it off with a credit card edge? I've heard that can work.
Good luck.

My first thought was also, what kind of glue? If its school glue or similar, soak the area in water. Keep dabbing with paper towel until the glue is gone. If its hot glue sticks, heat up the glue gun, swipe over the glue, remove excess glue with paper towels and small putty knife. Keep touching the glue until just the 'wet' spot remains. Place a paper towel over it and iron. Place a clean section of the paper towel over remaining spot and iron again. If its super glue, dab a cotton tip swab with diluted Goof Off and swipe the glue until soft and scrape it off. You will need to take soap and water and get the cleaner out of the pads fabric.
There is also a product called Un-Do Adhesive Remover at JoAnns.
Or, you could recover the pad with muslin and add the glue mistake to the list of things not to do again.

I use lighter fluid, the kind used for cigarette lighters to remove glue from stickers from books and things. Acetone is not the same as a glue remover. It damages any plastic. I don't like Goo Gone, it leaves an oily residue.
