Learn how to make your own DIY soft scrub cleaning product that will make ceramic sinks, tubs, and porcelain fixtures sparkle.
When I first tried this simple, natural soft scrub, I was surprised at how effective it is. Cleaning isn’t anyone’s favorite pastime, but a bright white sink makes the whole kitchen feel fresher and more cared for. This three-ingredient scrub is gentle, non-toxic, and perfect for ceramic and porcelain surfaces in the kitchen and bathroom. I began using it on my white sink and started cleaning daily—my husband jokes that the sink looks nicer than the rest of the house!
Over time I’ve been switching to more natural, less chemically intensive products where I can. We still use some conventional cleaners, but I’m gradually replacing harsh formulas with safer options. This soft scrub is one of the easiest and most effective replacements I’ve found for porcelain sinks, bathtubs, and toilets.
Supplies to Make DIY Soft Scrub
Gather these three simple ingredients:
- 3 tablespoons of Castile soap — a mild, plant-based soap works best.
- 1 cup of baking soda — provides gentle abrasive power and deodorizes.
- About 15 drops of citrus essential oil (lemon, orange, or a citrus blend) — helpful for cutting grease and adding a fresh scent.
Tip: Store supplies and finished scrub in glass containers when possible. Citrus oils can interact with some plastics over time, and glass is a stable, reusable option.
How to Make Your Own Soft Scrub Cleaner
The recipe is simple and quick to prepare:
- In a medium bowl, combine the baking soda and Castile soap.
- Add the citrus essential oil drop by drop while stirring until the mixture forms a dry, paste-like consistency. If it seems too dry, add a little more Castile soap a teaspoon at a time until you reach the desired texture.
- Transfer the scrub to an airtight container for storage.
The scrub should be a scoopable paste that holds together without running. It’s abrasive enough to remove stains but gentle enough for glazed porcelain and ceramic.
To use the scrub, dampen a cloth, sponge, or soft-bristled brush and take a small amount of paste. Gently scrub the stained area, working in a circular motion. For stubborn stains, let the paste sit on the spot for a few minutes before scrubbing. Rinse thoroughly with warm water and dry with a clean cloth. Repeat as needed for heavy discoloration.
This soft scrub works well on:
- Sinks (porcelain and ceramic)
- Bathtubs
- Toilets (for the porcelain surface)
- Stained countertops where a mild abrasive is safe
One stubborn ring around my sink drain had been there since we moved in; after a bit of elbow grease with this scrub it lifted off and the sink looked dramatically better. It may not turn every surface clinically white, especially if there are deep scratches or long-standing discoloration, but it significantly brightens and refreshes porcelain and ceramic finishes without bleach.
Storage and safety notes:
- Keep the scrub in a cool, dry place in an airtight container. Use within a few months for best scent and performance.
- Test the scrub on a small, inconspicuous area first if you’re unsure how a surface will react.
- Wear gloves if you have sensitive skin and avoid inhaling essential oil vapors directly.
Have you tried making any cleaning products at home? I’ve replaced many traditional cleaners with homemade alternatives and still have a few to go—laundry detergent is next on my list. Homemade cleaners like this soft scrub save money, reduce exposure to harsh chemicals, and are easy to customize with your favorite essential oils.
