How do I clean my shower doors?

Have you tried Vinegar? Or CLR?

Turtle wax

If the mineral deposit has etched the doors the damage could be permanent. If it is here is some info from someone who had the same problem and etched the door more with a pattern to hide the problem. https://www.thriftyfun.com/Adding-Etching-to-a-Glass-Shower-Door.html

If CLR doesn't work, try soft scrub with a scrubby

use straight CLR with single edge razor blade

CLR and arm power :)

I clean professionally and I use a soap scum remover such as scrubbing bubbles or lysol power bath. Spray it on the door, let sit for several minutes and then use a nylon scrubby to gently scrub the glass. Rinse. Repeat immediately while it is softened. Once shiny again, a weekly treatment will keep it shiny

I use a Brillo pad. They clean mine

If the minerals have actually etched into the glass, nothing will get it out. The only way to prevent it, when you have new glass is to get the whole family, to wipe off the water after showering, guests too! And maybe try using RainX, after weekly cleaning. I also like Fantastic, it will get new soapscum'so, a time least it won’t get worse, if the previous answers work f

Try baking soda
