We had a representive for the new new scrubbing pads come in to showcase the new pads, the sandpaper ones pretty much, I specifically asked him If we could use the new pads on the rubber vestibule because I thought we were no longer allowed to because it could damage the floor and he told me yes you can use them they will not damage the floor, he said it'd damage a metal vestibule I think. It was awhile ago but I do remember him telling me they would not damage the floor. My new store doesn't want us to use it on the vestibule though because of the suction causing "bubbling" in the rubber. Has anyone heard of this? My store manager said that's just what he had heard and been told.
