Cleaning the Slip Ring Sanding Sponge

May 29, 2018 | Tech Tips, CT, Siemens

Today, I’m going to talk about a previous video recorded by Kevin Brinkman, which discussed cleaning the slip ring using a very fine-grit sanding sponge. Today, I’ll explain how to clean that sponge.

Here we have the fine-grit rubberized sponge that we use to polish or remove any burrs on the slip ring. As Kevin mentioned in the earlier video, this sponge is used in a wide sweeping motion, running it over the rails of the slip ring.

By doing so, the sponge collects all the carbon dust from the carbon brushes that run across the slip ring. After just a few uses, the sponge will become blackened. To clean it, you can use very high-grade isopropyl alcohol, specifically, electronics cleaner that is 99.9% pure.

Simply pour the alcohol into a small wash basin, soak the sponge, and work it with your fingers to release the carbon dust. Personally, I’ve been using this same sponge for several years, cleaning it multiple times, and it remains highly effective.

Cleaning the sponge regularly prolongs its life and ensures it continues to clean your slip ring effectively without transferring materials.
