Understanding Concrete Surfaces
Concrete tables—whether sleek indoor dining pieces or rugged outdoor patio furniture—are stylish, heavy, and durable. However, despite their industrial strength, concrete is a porous material. Without proper cleaning and protective sealants, concrete easily absorbs oils, wine, coffee, and water rings.
Routine Daily Cleaning
For everyday maintenance, keeping your concrete table spotless requires minimal effort:
- Wipe down the surface using a soft microfiber cloth dampened with warm water and a few drops of mild, pH-neutral dish soap.
- Dry the table thoroughly with a clean towel to prevent water spots from forming on unsealed spots.
Products to Avoid
Because concrete is alkaline and sensitive to harsh chemicals, certain common household cleaners will permanently ruin the finish:
- Never use vinegar, lemon juice, or citrus-based cleaners: Acidic solutions etch and dissolve the cement paste binding the concrete together.
- Never use bleach or ammonia: These harsh chemicals degrade protective sealants and discolor the pigment.
- Avoid abrasive scouring pads: Steel wool and harsh scrubbers scratch polished concrete finishes.
Removing Tough Stains
If spills occur and leave behind marks, tackle them according to the stain type:
- Food & Grease Stains: Create a thick paste using baking soda and water, apply it over the stain, cover with plastic wrap for 24 hours to draw out the oil, then wipe clean.
- Water Rings: Buff gently with a very fine grit sanding pad (if unsealed) or clean with neutral soap.
Re-Sealing Your Concrete Table
Protective sealants prevent liquids from penetrating porous concrete. Test your table’s seal annually by dropping a small amount of water onto the surface: if the water beads up, the seal is intact. If the water darkens the concrete and sinks in, it’s time to clean the table thoroughly and apply a fresh coat of manufacturer-recommended concrete sealer.

FAQ
Can I use vinegar to clean a concrete table?
No! Vinegar is acidic and will permanently etch, dull, and erode the smooth surface of a concrete table.
How do you get oil stains out of concrete?
Apply a baking soda and water poultice over the stain, cover it with plastic wrap overnight to pull out the grease, and rinse clean.
How often should a concrete table be sealed?
Most concrete tables should be re-sealed every 1 to 2 years, depending on indoor versus outdoor exposure and daily use.
Are outdoor concrete tables waterproof?
Concrete is naturally porous, meaning outdoor tables absorb moisture unless treated with a waterproof penetrating sealer.
