Wash away any grit and hair. Use your shower to wash away any debris in the way. If you have a removable shower head, use it to spray around the tub. Otherwise, use a cup or small bucket to pour water around. If you have a lot of hair and debris in your tub, it’s best to wipe it away with a paper towel before you rinse the tub using your shower head. Otherwise, you may accidentally clog up your drain.
Try a grapefruit and salt scrub. The acid from the grapefruit combined with the abrasiveness of the salt helps to scrub away grime. Plus, the grapefruit leaves your bathroom smelling like citrus. Cut a grapefruit in half. Cover the open half with salt. Sprinkle salt on the wet tub.
Scrub the tub with the grapefruit, releasing juice as you go. You may need to switch to another half to scrub away all the grime in your bathtub. You may even need more than one grapefruit. Rinse away any salt and pulp.
Create a bathtub and sink scrub. You may already have the ingredients in your home, especially if you like organic soaps. Mix 1 cup of baking soda with 1/2 cup of Castile soap and a few drops of peppermint or tea tree essential oil. Use the mixture on a sponge to scrub down your tub. It works especially well on soap scum. Rinse it away when your tub is clean.
Make a vinegar spray. Vinegar is slightly acidic, so it can help remove bacteria and stains. In a clean spray bottle, add 1 cup of vinegar and 1 cup of water. Shake vigorously. Spray it on your tub. Use a sponge to scrub it down. Rinse away the vinegar.
