Look for alcohol with a high concentration, such as 70% or more. [1] X Research source You can also try vinegar or baby oil to dissolve the glue. [2] X Research source
For some types of laptops, such as the MacBook Pro, you’ll need to detach the baseplate before attaching the feet. This is because the feet have a backing piece that needs to be pushed through a hole in the baseplate and glued down from the other side. [3] X Research source
For some computer models, the process can be a little more complicated. For example, if you have a MacBook, you may need to take the baseplate off your computer and push the backs of the feet through the holes on the bottom. If your replacement feet come with special instructions, follow them carefully to make sure your feet fit properly and stay in place.
Use a cotton swab dipped in isopropyl alcohol (at least 70%), vinegar, or baby oil to dissolve any stubborn glue.
If any of the original feet are still attached, use them as a guide to determine how high you want to make the mound of glue.
You can also make your own silicone glue by mixing a little cornstarch with 100% silicone caulk. Keep adding small amounts of cornstarch until the caulk has a putty-like consistency and isn’t sticky to the touch. [11] X Research source
