Hello, I have an interesting setup in my master bath. I have tile but above the tile is another section of drywall with paint. That section has become stained with soap scum. I’ve tried several times to clean it but the difficult part is, I want to remove the soap scum but not risk taking the paint off of the walls. Does anyone have a suggestion for cleaning this area without damaging it?

Also, for the tile walls and the base of the shower as well as the glass doors I use a drill attachment (See attached photos). This does the job to a degree but the grout always looks stained even after cleaning. I’ve also used toilet bowl cleaner on the recommendation of others but it doesn’t seem to fully do the job. I bought a steamer (See attached photos) and this doesn’t seem to do the job either. (All of the brush attachments that came with it melted) Looking for suggestions from others on a better steamer for all of these areas as well as cleaning solutions/techniques to make this easier as cleaning the shower has become a large sweaty chore. Thanks in advance for any suggestions. Please provide any product links or links to cleaners necessary. Thanks
