white vinegar soap scum

What is the best way to remove soap scum from shower doors and tile?
I tried a solution of white vinegar and water and only helped a little. Has anyone used Kaboom? Any other product that works and is not too strong? Thanks!
I have kaboom although this is not the best smell works. Just spray and leave for 3-4 min then spray a little water and add more kaboom leave for 3-4 minutes bush that reall good
