Cleaning and Stain Removal - Scouring pad for dirty shower

My automatic shower cleaner has cleared about 75% of the crud in my shower stall since I started using it a couple weeks ago. The little that remains is going to take some elbow grease to get off the fiberglass and anodized aluminum doors, but the Mr. Clean Magic Eraser is not cutting through and is falling apart in the process. I'm looking for something both a little more aggressive and more durable. Any suggestions?

Hey mitch i have this great idea for you. Head over to a janitoral store and buy a 20 inch blue floor pad. In the middle of the pad there should be a punch out little circle, where the pad would hook onto a floor machine. Take that circle and you should be able to outline them with a sharpie on the pad and cut out how many you can or differenet sizes. They will last a good long time and do a great job. you can prob pick a pad up for around 5 or 6 bucks a pad, but get a ton of scrubbies out of them. I bring them home for the wife all the time .

Thanks doc, that sounds great.

Just thinking, Black and Decker has a power scrubber called Scumbuster, just for these kind of things. Don't know what it costs but no elbow grease needed.

Hmm, a power tool, you say? Gonna have to look into that.
