If it's store bought, that's fine, but homemade would be even better!
It's driving me crazy!!
Magic erasers work but take a lot of elbow grease and I am lazy.
S.O.S pads got 3+ years of accumulated soap scum off of my grandpas tub and shower. I soaked it down in bleach for about 2 hours first, rinsed it, and then used the S.O.S pads to scrub off what was left.
To this day I still use them on soap scum, they work like nothing I have ever tried, and don't wear out as fast as the magic erasers.
i am having a horrible time! we just bought a house and i swear the previous owners NEVER cleaned the soap scum off the glass shower doors...UGH! i have tried tons of cleaners that i had, but so far nothing is working. i just read a thread about using equal parts white vinagar (warmed 2 min in microwave) and blue dawn (classic). mix in spray bottle and spray the heck outa the soap scum! let it sit 2 hours, wipe down with wet rag and it should all be gone! i saw pix, it looks really promising. i am trying today and will let you know my own personal experience. heres hoping!
I use those little Doby sponges that are covered in a plastic mesh, plus Bon Ami, plus *several* passes of heavy duty scrubbing. How much will also depend on the hardness of the water-- places with harder water will have more soap build up. This kind of sponge won't scratch surfaces.
And it will be harder to remove, something about the levels of calcium in the water makes it bond stronger.
I have had good success with scotch brite pads and a paste of borax and dish detergent. It took a lot of elbow grease but the maintenance now isn't too bad.
