Not sure if this is the right spot for this post, but I'm trying to find out what to you to clean the inside shell? I thought I read somewhere that bleach is good to use, but I just wanted to get some suggestions. The tub hasn't been used for about a 1 1/2 years so it needs a bit of cleaning on the inside. Any suggestions would be great. Thanks!

We use windex and a paper towel when we acquire a used and neglected tub in need of a good shell cleaning...works well
