Assuming you are referring to cleaning a shower made of different materials such as tile, porcelain, or fiberglass, here are some tips:
-Use a non-abrasive all-purpose cleaner or bathroom cleaner. You can also make your own by mixing 1/2 cup vinegar with 1/4 cup baking soda and 1 quart warm water. Be sure to test this on a small area first to make sure it does not damage the surface.
-Start by spraying the entire shower with the cleaner of your choice. Let it sit for a few minutes so it can start breaking down any soap scum or dirt.
-Next, use a soft sponge or cloth to gently scrub the surfaces. A toothbrush can also be used to get into small crevices and corners. Rinse well after scrubbing.
-For tougher stains or areas that need extra attention, you can make a paste out of baking soda and water and apply it directly to the problem areas. Let it sit for 10-15 minutes before scrubbing and rinsing clean.
