I have a 30 year old tub that we installed when it was brand new. I am the only one who has ever used the tub and I clean it after each use. These tub is in great shape other than these spots.

The spots have appeared in the last few years and seem to be multiplying. I have no idea what they are from and would really like to remove them.

I’ve scrolled through other posts about tub stains but haven’t found one that is similar in appearance to mine.

Can anyone help out with a removal method?
