For mirrors and glass, Windex works for me. Spritz it straight into the glass and use a cloth or paper towel to rub over until clean. You will need to have a light pressure with the cloth to rub it over and remove the residues. However, this is just for regular dirt and dust. If you have shower glass with soap scum, you will need to use something a bit abrasive like Jif or Gumption to get it back to clean. After that can be maintained with a squeegee every time you shower, but frankly I can’t be bothered with that. Just clean it regularly with jif.
