How do you clean a safe step walk in tub?

A clean bathtub isn’t just about aesthetics; it’s also about hygiene. Regular cleaning prevents the buildup of soap scum, grime, and potentially harmful bacteria. But what’s the most effective way to get your bathtub sparkling clean?

Why Dawn Dish Soap?

Dawn dish soap is more than just a kitchen cleaner. Its grease-cutting formula is remarkably effective at breaking down soap scum, the primary culprit behind that dull, dirty film on bathtubs. Moreover, Dawn is gentle on most bathtub surfaces, making it a safe and versatile choice. The overnight soaking method, often mentioned in online forums, leverages Dawn’s cleaning power to loosen grime while you sleep.

Materials You’ll Need

  • Dawn dish soap: Opt for the original blue Dawn for its superior grease-fighting capabilities.
  • Baking soda: A mild abrasive and natural deodorizer.
  • White vinegar: A natural disinfectant and cleaning agent.
  • Spray bottle: For mixing cleaning solutions.
  • Scrub brush or sponge: Choose a non-abrasive tool to avoid scratching your bathtub.
  • Microfiber cloth: For drying and polishing.

Step-by-Step Instructions

  1. Preparation: Clear away any bath toys, bottles, or other items from the bathtub.
  2. Rinse: Wet the entire surface of the bathtub with warm water. This will help loosen initial dirt and grime.
  3. Apply Dawn: Generously squirt Dawn dish soap around the bathtub, focusing on areas with visible soap scum or stains. If you’re planning to soak overnight, leave the soap as is and proceed to step 7.
  4. Sprinkle Baking Soda: Evenly distribute baking soda over the Dawn. The combination of Dawn and baking soda creates a powerful cleaning paste.
  5. Scrub: Using your scrub brush or sponge, gently scrub the entire bathtub surface. Pay extra attention to areas with stubborn stains. For hard-to-reach corners, consider using an old toothbrush.
  6. Vinegar Rinse: Fill your spray bottle with equal parts white vinegar and water. Spray the solution over the entire bathtub. The vinegar will help remove any remaining soap residue and disinfect the surface.
  7. Overnight Soak (Optional): If you have time, leave the cleaning solution in the bathtub overnight. This is especially beneficial if you have significant soap scum buildup.
  8. Final Rinse and Dry: Thoroughly rinse the bathtub with warm water, ensuring all cleaning residue is removed. Dry the surface with a microfiber cloth for a sparkling finish.

Additional Tips and Insights

  • For tough stains: Create a paste of baking soda and water, apply it to the stain, and let it sit for 15-20 minutes before scrubbing.
  • Natural alternative: If you prefer a natural cleaning solution, substitute the vinegar rinse with a mixture of lemon juice and water.
  • Prevent future buildup: After each bath or shower, quickly rinse the bathtub with warm water and wipe it down with a squeegee or towel.
  • Regular cleaning: Aim to clean your bathtub thoroughly at least once a week to prevent the buildup of soap scum and grime.

Why This Approach Works

This cleaning method combines the grease-cutting power of Dawn with the mild abrasiveness of baking soda and the disinfecting properties of vinegar. The overnight soaking amplifies Dawn’s effectiveness, allowing it to penetrate and break down stubborn soap scum. This approach is not only effective but also safe for most bathtub materials, making it a versatile solution for a wide range of households.


A clean bathtub is not only visually appealing but also crucial for maintaining a healthy bathroom environment. By following these trick, you can achieve a sparkling clean bathtub with minimal effort.
