hardware stores carry caulk remover. the tub should clean up fine. the surround is too short and showering will damage the exposed drywall over time-- i'm surprised it looks okay now, but the exposed area is off to the side. hardwRe stores carry the surround panels and they are common do it yourself projects ( obviously yours is a diy job
The tub is filthy because we dont use this tub that much?? Seems like the opposite would be true. That if you did not use it that much it should be pristine. If your "cleaning lady" is not doing a good job then get a new cleaning lady.
Sorry, didn't give all the details. We got the tub as is now when we moved into the house, so we were using other bathrooms in the house instead. Yeah, need a new cleaning lady.
