Adding lubricant to the side rails of the housing or sides of the stem remedies the scratchy noise and feel. Lubricant should also be placed on the bottom of the stem and spring. This mod is used in conjunction with the tape mod (see below).
Various mixtures of lube can be used. Krytox 205g0 is a safe bet, but thinner lubes such as TryboSis 3203 may be more preferable for a lighter switch.

Simsalaba printed TPU switch dampeners that fit on the top of choc-compatible keycaps. At only 0.4mm tall, the travel reduciton is not noticeable.
