I think some of the cleaners use soap to remove oils from your hands on the rubber, which is a good thing....but then you have soap on your rubber. For that reason, I use them sparingly and then use plain water to take the soap off. You may also have a buildup of that soap in your sponge, so rinse that out too.I clean them with this Yinhe Rubber Cleaner bottle with a sponge on top. I apply whatever it is on the bottle (seems like soap lol) and wait for like 15 seconds, and then dry it with another sponge. I do this always at the end of my sessions and then put on the white plastic film that comes with it on the packaging.
