                      I just got done trying out a recipe for removing that nasty mystery stuff on your bathtub.  I learned before that it's a combination (in my geographic area) of soap and minerals.  That's why soap scum remover never seems to get the job done and the same with lime/mineral (Lime A Way, CLR) removers.
  So I tried this knowing it wasn't a 2 second solution. Equal parts vinegar & water.  I used 1/2 cup each.
  Cornstarch I mixed in corn starch to the water before incorporating it into the vinegar.
  Heated that on the stove until it got the thickness I wanted.
  Dishsoap I used a couple of drops of Dawn.
  I "painted" this on to the horizontal surface of my bathtub ledge.  I let it sit until the next day.  It took days of using my power drill & scrub brush to get it clean, but it came off.
