Hello, We have a 2 piece shower unit with a gap between the wall and the tub. Should I use silicone to fill this gap? The gap is 1/16 to 3/16 of an inch and water goes in and lays in the back of it. We have trouble cleaning this gap. I have not used silicone because I am afraid mold or mildew will get in this or in the silicone.
Thanks.
