As long as the edges of the alcohol wipe you have used previously are still clean, you can use the same wipe for this step. If you don’t have a clean alcohol wipe or want a little bit more control when cleaning some harder to reach areas, you could use a cotton swab dipped in rubbing alcohol instead.

You can soak your glasses for much longer than this, even overnight, though this long exposure to water and shifting temperatures may damage your glasses.

Alternately, you can wait for your glasses to air dry. This will prevent any streaks on the lenses that can come from cloth-drying but will take much longer.

Make sure to keep track of these tiny screws as you clean the nose pads. They can be difficult to replace. Some glasses will have nose pads attached differently or as part of the frame. If you can’t find a way to detach your nose pads, you can skip this step.

A lotion-free and moisturizer-free dishwashing liquid can work in place of hand soap if needed.

If you are cleaning the nose pads while they are still attached to the glasses, be careful not to brush the lenses at all. They will scratch easily and are very difficult to repair or replace.

Be careful not to get any alcohol on the lenses of your glasses, as this can damage them. If you’ve removed the nose pads from your glasses, you can also soak them in a small amount of rubbing alcohol. Leave them to soak for a minute or two before removing, rinsing, and drying.

Never clean or dry your glasses with a paper towel, cloth or your clothing. These can leave lint and dust behind, and may even scratch your glasses.

The size of a nose pad can be found by measuring along the longest part of one pad. The sizes will generally be listed in millimeters. Replacement nose pad kits will come with all of the tools you need to replace nose pads, including a screwdriver, new screws, a magnifying glass, and replacement nose pads. These can make the whole process very streamlined and easy to repeat in the future. [6] X Research source

If the nose pad isn’t attached by a screw, it will likely be a snap-on nose pad. Use a small, flathead screwdriver to pry the old nose pads out of place. They should easily pop out. [8] X Research source The same screws can be used to attach the new nose pads, but make sure they are intact and functional before doing so. Check the threading and the head for any signs of damage.

If you have snap-on nose pads, simply rest them on the mounts on your glasses and push until they click into place. [11] X Research source [12] X Research source If getting the nose pads or screws into the right place is too difficult, use a small pair of tweezers to hold them and shift them around. If you have D-shaped nose pads, make sure they are attached so that the flat edge of the D faces away from the face.
