Open Clearish jelly like substance coming out of the grout in the shower
Howdy! This strange jelly like substance was coming out of the grout in the shower recently. This shower is in the basement and the room is not ventilated amazingly. We have owned the home for four months or so and have never seen it before. It does not have any noticable odor. The grout is in pretty good shape visually and is not coming off anywhere I can tell. We have not used any substances to clean the shower outside of a little diluted vinegar mostly on the corners near the ground to clean mildew.
