Clean your glass mousepad weekly with isopropyl alcohol.

Yes, isopropyl alcohol is safe for glass mousepads, and weekly cleaning is enough to keep the glide smooth.

Oil and dust build up on the surface over time. A clean glass mousepad feels almost frictionless. After a week of use, you’ll start to notice drag. A quick wipe brings it back.

Isopropyl alcohol (70% or higher) is fine for bare glass. It evaporates quickly and doesn’t leave residue. The concern is coatings — some glass mousepads have a hydrophobic or oleophobic layer. Most modern glass pads use a coating that resists fingerprints. Alcohol is generally safe for those, but check the manufacturer’s specific cleaning instructions to be sure. I’ve never seen one complain about isopropyl.

Just don’t use acetone, bleach, or abrasive cleaners. A microfiber cloth with a little alcohol does the trick.

Trust your fingers — if the pad feels tacky, it’s time.
