What's a fast, easy and inexpensive way to clean mildew and soap film

This sounds like a shower stall? Try this, since they're calling it the "miracle cleaner!"

This is similar to what I do, except I put 1/2 vinegar. 1/2 cheap bottled lemon juice and a drop or 2 of dishwashing liquid in the scrubby handle. It works really well. Once you get it all off, it may take a couple of tries, get into the habit of using a squeegee or an absorbent microfibre cloth after the last shower every day. You will hardly ever have to worry about soap scum again. It literally takes only 2 minutes, and really cuts down on scrubbing. Now I only use the scrubby and solution for a quick clean and rinse. Alternatively Tilex Daily Shower Cleaner works, but it is more pricey, and I found I had to change the caulk more frequently. Don't use the $ store knockoffs, when we did, the caulk started to peeled off within 2 days!!!

Pinesol, or vinegar and water with Fabulosa for a good aroma. 😇
