Bathroom Scrubbing Paste

A simple baking-soda and soap paste for routine residue on compatible bathroom finishes. This paste cleans; it does not disinfect.

Mixing time estimate 5 minutes
Listed yield 1 cup
Method difficulty Easy

Ingredients

  • 1 cup Baking soda
  • 1/4 cup Liquid castile soap
  • 2 tablespoons Water (Add only enough to form a spreadable paste)
Listed uses: manufacturer-approved glazed ceramic or porcelain after a spot test
Avoid or check first: marble, granite, natural stone, delicate coatings, brass, aluminum

Why This Recipe Works

Baking soda provides mild abrasion while diluted soap helps lift routine residue. Either can mark a delicate coating, so check the fixture or tile manufacturer’s instructions and test a hidden area first. This mixture is for cleaning only.

Instructions

  1. Mix dry and wet: In a bowl, combine baking soda with castile soap. Stir until you get a paste-like consistency.

  2. Add water slowly: Stir in only enough water to form a spreadable paste.

  3. Spot test: Apply a small amount to a hidden area, rinse, and check the dry finish before continuing.

  4. Apply gently: Use a soft cloth or non-scratch sponge. Do not let the paste dry on the surface.

  5. Rinse and dry: Remove every trace of paste with clean water, then dry to check for residue.

Tips & Variations

  • Start gently: Extra dwell time and pressure can damage finishes; repeat a light pass instead.
  • Grout varies: Do not use on unsealed, cracked, colored, or manufacturer-restricted grout.
  • Visible mold: Fix the moisture source and follow EPA mold guidance rather than adding essential oil to this paste.

Safety Notes

  • Do not add vinegar: Acid reacts with the soap and leaves ineffective residue.
  • Wear gloves: Prolonged contact with baking soda can dry out skin.
  • Don’t use on stone: Abrasion and an unsuitable pH can damage natural stone or its finish.

Storage

Mix only what you need and discard the remainder after use. Do not store a wet paste.
