Removing keycap engraving

Is there an easy and safe way to remove laser engraving? Keyboard is CM Quickfire.

Don't want to order blank keycaps because $40 for a set of keycaps is too much.

 

Depending on what type of keycaps they are, you might be able to just sand the tops to remove the etching.

Small tube of plastic body filler, small plastic spatula, sandpaper, spraypaint. About $11-$17 to fix, plus time to pop off all the keys, fill the engravings, wait for the filler to set, and sanding and painting, then popping them back on. About 12 hours total with dry time. (you might want to give the keys a good 24 hours for the paint to cure before going about a heavy bout of gaming.
