Cleaning a bathtub can be done effectively using the following steps:

1. Gather supplies: You’ll need rubber gloves, a non-abrasive cleaner or mild bathroom cleaner, a sponge or soft cloth, an old toothbrush or small brush, baking soda (optional), vinegar (optional), and a bucket of warm water.
2. Remove any items: Take out bath mats, shower curtains, or any other items in the bathtub.
3. Rinse the tub: Use a handheld showerhead or a bucket of warm water to rinse the tub thoroughly, removing any loose dirt or debris.
4. Apply a non-abrasive or mild bathroom cleaner to the tub’s surfaces. Follow the instructions on the cleaner’s label for the best results. If you prefer a natural alternative, you can create a paste by mixing baking soda with a small amount of water and applying it to the tub.
5. Scrub the surfaces: Use a sponge or soft cloth to scrub the bathtub surfaces, focusing on areas with soap scum, stains, or grime. Use an old toothbrush or small brush to scrub gently for hard-to-reach areas or grout lines.
6. Let it sit: If using a cleaner that requires dwell time, allow it to sit on the surfaces for the recommended period mentioned on the cleaner’s label. This helps loosen tough stains or soap scum.
7. Rinse thoroughly: After the cleaning solution has had time to work, rinse the tub thoroughly with warm water. Ensure that no residue or cleaner is left behind.
8. Address stubborn stains: You can try using vinegar for stubborn stains or mineral deposits. Apply vinegar to the affected areas, let it sit for a few minutes, and then scrub gently with a sponge or cloth. Rinse thoroughly afterward.
9. Dry the tub: Use a clean, dry cloth to wipe down the tub surfaces to prevent water spots or streaks.
10. Clean fixtures: Don’t forget to clean the faucets, handles, and any other institutions in the bathtub using an appropriate cleaner or vinegar solution. Wipe them dry afterward.

Regular cleaning and maintenance of your bathtub will help prevent the buildup of grime and stains, making future cleaning easier.
