  • Wiping it down with a towel after showering is always helpful. For the buildup that is already there, use an old toothbrush and some vinegar.

    I use a mixture of Blue dawn dish soap (5-6 oz) in a 32 oz empty water bottle, fill with vinegar. In the cap, either make slits with a knife or poke holes and give the bottle a mix. Spritz all over your shower/tub, then brush with a dollar store broom tto spread it around. Let set for about 30 min rinse well. Keep this broom dedicated for this purpose so your shower does not get scratched. Repeat as needed.


    To prevent after you have cleaned it, wipe or squeegie til dry. Then coat with automotive wax, some people use Rainex with success.

    Vinegar is best to remove but it looks like you have rust as well. You can brighten with a scrub of hydrogen peroxide & baking soda or sprinkle the baking soda then spritz with vinegar (it will boil). I like to use a stiff crevice brush but a cheap toothbrush will do in a pinch.

    Rain-X has a preventive product that can help, designed for the shower.

    Yeap I also use the vinegar and dawn mix. I found that by waxing the shower walls (not the floor) stuff runs off without staining much more.

    Might be more than soap scum. Looks like you have rust coming from under the escutcheon plate. You need to disassemble the faucet and see what's going on inside. Remove the faucet handle, the spacer, and then the escutcheon trim.

    Hi Tivka: What I do is a couple of times a week, I use an old toothbrush to clean around the tap. I spray it with bathroom cleaner and then brush and rinse. What you might try, once the tap is clean, is to spray or wipe it with some wax. Furniture or car, it doesn't matter. But, it's just what happens when you wash your hands and don't rinse the area afterwards.

    Just apply cleaning vinegar to the area once a week or 10 days, let sit for 15-20 minutes and then rinse and dry.

    Heat up 1 cup of white vinegar, mix in about 1/4 cup of Dawn Premium. Not the dollar store kind, because it is too thin. When mixed, pour into a spray bottle and fill with water. Shake.

  • I have a few shower cleaning tips here though it looks from your picture that more is going on such as rust. You might do some investigating to see what’s going on.

    I can vouch for the vinegar idea 100% Even better they make "After shower" sprays that are vinegar based. You literally just spray the entire shower down quick after each shower.

  • Because hard water includes mineral salts, it might lead to the development of soap scum. Soap scum develops as a result of wet bar soap interacting with tap water minerals. These minerals interact with the bath soap that has been diluted to create a scum or film that adheres to surfaces. Instead of using regular bar soap, switch to glycerin-based liquid or gel body soaps. Your tile and glass shower doors are stained by the talc and paraffin in bar soap.

    Hi Tivka, hope this helps you. First use vinegar and baking soda to clean the soap scum

    Then be sure to dry the inside of your shower &n tub after every use, seems like a pain, but you will never have to scrub scum again! You can use a u for smooth areas, like walls and tub sides.
