a DIY version inspired by the ingredients in Tilex Disinfecting Instant Mold and Mildew Remover

Here's a DIY version inspired by the ingredients in Tilex Disinfecting Instant Mold and Mildew Remover, using more common household items:

Ingredients:

• 1 cup water
• 1 cup household bleach (Sodium Hypochlorite, usually around 5-6%)
• 1 teaspoon baking soda (mild abrasive, adds cleaning power)
• A few drops of dish soap (as a surfactant to lift dirt and grime)
• 1/4 teaspoon sodium hydroxide (optional, handle with care, but for safety, you can substitute with baking soda for a gentler version)

Instructions:
1. Mix the Bleach and Water: In a spray bottle, combine 1 cup of water with 1 cup of household bleach. Be cautious when handling bleach—wear gloves and work in a well-ventilated area.

2. Add Baking Soda and Dish Soap: Add 1 teaspoon of baking soda and a few drops of dish soap to help lift the mold and dirt from surfaces. Shake the bottle gently to combine the ingredients.

3. Optional – Sodium Hydroxide Addition: If you're comfortable handling sodium hydroxide (lye), you can add a tiny amount (1/4 teaspoon) for extra cleaning power. If not, stick to the baking soda.

4. Spray on Mold or Mildew: Spray the mixture onto the moldy or mildewed surface. Let it sit for 5-10 minutes to allow the bleach to disinfect and remove stains.

5. Scrub and Rinse: Use a scrub brush or sponge to clean the surface. Rinse thoroughly with water and dry with a clean cloth.

Safety Notes:
- Always use gloves and work in a well-ventilated area when working with bleach or sodium hydroxide.
- Never mix bleach with vinegar or ammonia, as this can create dangerous fumes.
