How do I get ride of soap scum ?

Not sure what that is? Regional term? Colloquial term?

Scrub with hot soapy water. Ammonia and water may work well too.

Hello, could you explain what you mean by dodo scum?

I am so sorry that was supposed to say soap scum

If the scum is on the shower doors sometimes you have to get a little more serious. People have said they scraped the doors with a razor blade first, then used a bathroom cleaner and a Magic Eraser to finish the job.

Hello, I looked at all the reviews and The Bucko Soap Scum and Grime cleaner had one of the best reviews and it said The Bucko Shower Soap Scum and Grime works well to remove the gunk, while leaving a beautiful shine behind. It makes glass shower doors, textured acrylic bathtubs, chrome fixtures, and sinks with all kinds of buildup look sparkling clean. If you want a commercial product, this looks like a good one and here is a link to check it out.

Hello, I have never tried it but I am going to cause I have stains that just won't come off. I have tried everything else. May have to paint the tub if this stuff doesn't work on it. The reviews say it has a light lemon scent.
