How to Acid Wash a Tile Shower

Acid washing is a cleaning process that uses a strong acid, such as hydrochloric or muriatic acid, to remove built-up dirt, grime, and mineral deposits from tile surfaces. While it can be an effective way to clean tile showers, it's important to take safety precautions and follow the proper steps to avoid damaging the tile or grout.

Here's a step-by-step guide on how to acid wash a tile shower:

1. Prepare the Area:

- Remove all shower curtains, rugs, and other items from the shower area.

- Cover nearby surfaces, such as countertops, fixtures, and floors, with plastic sheeting to protect them from acid splashes.

- Open windows or turn on the exhaust fan to ensure proper ventilation.

2. Wear Safety Gear:

- Put on protective clothing, including gloves, goggles, and a long-sleeved shirt and pants.

- Respirators are also recommended to protect against acid fumes.

- Avoid direct contact of acid with skin or eyes.

3. Test the Acid:

- Before applying the acid to the entire shower, test it on a small, inconspicuous area of the tile to ensure it doesn't cause damage.

4. Apply the Acid:

- Mix the acid according to the package instructions, usually a dilution of 1:10 with water.

- Apply the acid solution to the tile surface using a sponge, brush, or spray bottle.

- Let the acid sit for a few minutes, but not longer than the recommended time on the product label, as prolonged exposure can damage the tile.

5. Scrub and Rinse:

- Use a scrub brush or non-abrasive pad to agitate the acid solution on the tile and grout.

- Rinse the shower thoroughly with clean water to remove the acid and loosened dirt.

6. Neutralize the Acid:

- After rinsing the shower, apply a neutralizing solution, typically baking soda mixed with water, to the tile and grout.

- Let it sit for a few minutes, then rinse again with clean water. Neutralizing the acid prevents any residual acid from damaging the tile or grout.

7. Let it Dry:

- Allow the shower to dry completely before using it again.

8. Reseal the Grout:

- Once the shower is dry, consider resealing the grout to protect it from future staining and water damage.

Important Tips:

- Always read and follow the manufacturer's instructions for the acid cleaner and any other products you use during the process.

- Never mix different types of cleaning solutions, especially bleach, as it can create harmful fumes.

- Work quickly and efficiently to avoid leaving the acid on the tile for too long.

- Use a soft cloth or sponge rather than a hard brush to prevent scratching or damaging the tile surface.

- If the tile or grout is severely stained or damaged, consider hiring a professional tile cleaning service for the best results.
