Well, the shower has been cleaned after over 3 hours of work!!! If I took before and after pics, you would have been amazed, but the before pic would have been so embarassing, I decided against it. Here is how it went down:
1. Some Ajax on the dirtiest part got the outer layers of sludge off, leaving the soap scum and mildew to be exterminated.
2. 3 uses of Tilex Mildew got rid of most of it.
3. 3 uses of Tilex Soap Scum got rid of most of it, but not as much as the Tilex Mildew got rid of mildew. So comes the next step....
4. I scrubbed the Tilex Soap Scum into the soap scum that wouldn't come off, and 90% of it came off.
5. Tried some Ajax on the mildew parts that wouldn't come off. It didn't get rid of the mildew but made it easier to get off.
6. I went down on my hands and knees and sprayed Tilex Soap Scum in the tub. My legs burned a little after that, but only for a few minutes. I rinsed them with water and they were ok.
7. I tried some Tilex Mildew on the parts that wouldn't come off but it didn't work as well. 95% of the mildew was gone anyway. Tried some Ajax on it and it worked a little better.
8. I used the Clorox with Teflon foam all over and left the shower and tub pretty clean.
Keep in mind for all of these I rinsed every spray off with water before putting on the next thing. I am highly pleased with the results, and my father, whose birthday is Thursday, will be amazed when gets home from Cleveland Friday night. Thanks for all your help and suggestions; they worked!!!
