How to Clean Concrete Floors

Concrete floors have become increasingly popular in modern homes, lofts, and commercial spaces for their industrial aesthetic and durability. Whether polished, sealed, stained, or raw, concrete floors require specific care depending on their finish type. Here's a complete guide to cleaning and maintaining concrete floors effectively.

Types of Concrete Floors

• Sealed concrete: Has a protective topcoat (epoxy, polyurethane, or acrylic sealer). Most common in homes. Easier to clean and stain-resistant.
• Polished concrete: Ground and polished to a smooth, glossy finish. Very durable and easy to clean.
• Stained concrete: Has acid stain or water-based stain applied for color. Usually also sealed.
• Unsealed/raw concrete: Highly porous, stains easily, requires more careful cleaning and should be sealed.
• Epoxy-coated concrete: Common in garages. Very durable, chemical-resistant, easy to clean.

What You'll Need

• BPAWA Microfiber Flat Floor Mop with 4 Washable Pads
• Better Life Floor Cleaner – Citrus Mint, 32 Fl Oz (Pack of 2) – pH-neutral, safe for sealed concrete
• Lucy's Family Owned Distilled White Vinegar (1 Gallon) – for light cleaning of sealed concrete (not acid-stained)
• Nutricost Baking Soda (2 LBS) – for deodorizing and light scrubbing
• A stiff-bristle brush (for deep cleaning)
• HOMEXCEL Microfiber Cleaning Cloths (Pack of 12)
• A wet/dry vacuum or mop for rinsing

What to Avoid on Concrete Floors

• Acidic cleaners on acid-stained concrete: Can alter the stain color
• Harsh alkaline cleaners: Can damage sealers and etch unsealed concrete
• Abrasive scrubbers on polished concrete: Scratch the polished surface
• Ammonia-based cleaners: Can discolor concrete and damage sealers
• Bleach (regular use): Can discolor concrete and degrade sealers over time

Daily Maintenance

Sweeping and Dust Mopping

Sweep or dry dust mop concrete floors daily to remove grit, dust, and debris. Concrete is hard but grit ground in by foot traffic can scratch polished surfaces and dull sealers over time. A microfiber dust mop is ideal for capturing fine particles.

Weekly Cleaning: Sealed and Polished Concrete

Step 1: Sweep or Vacuum First

Remove all loose debris before wet mopping.

Step 2: Mop with pH-Neutral Cleaner

Dilute Better Life Floor Cleaner in warm water. Mop with a damp microfiber mop, working in sections. Concrete can handle more moisture than hardwood, but avoid pooling water on unsealed concrete.

Step 3: Rinse Thoroughly

Mop again with clean warm water to remove all cleaner residue. Residue on concrete creates a dull film and attracts dirt.

Step 4: Allow to Dry

Allow to air dry or use a dry mop pad to speed drying. Polished concrete dries quickly and shows water spots if not dried evenly.

Cleaning Unsealed Concrete

Unsealed concrete is highly porous and requires more care:

1. Sweep thoroughly.
2. Mix a small amount of dish soap with warm water.
3. Scrub with a stiff-bristle brush, working in sections.
4. Rinse thoroughly with clean water — use a wet/dry vacuum to remove rinse water if possible.
5. Allow to dry completely.
6. Consider applying a concrete sealer to make future cleaning much easier.

Cleaning Epoxy-Coated Concrete (Garage Floors)

Epoxy coatings are very durable and easy to clean:

1. Sweep or blow out debris with a leaf blower.
2. Hose down or mop with warm water and a small amount of dish soap.
3. Scrub any oil or grease spots with dish soap and a stiff brush.
4. Rinse thoroughly.
5. Allow to dry completely before parking vehicles.

Removing Stains from Concrete

• Oil and grease: Apply dish soap directly to the stain, let sit 15 minutes, scrub with a stiff brush, rinse. For set-in oil, apply cat litter or baking soda to absorb, then scrub with dish soap.
• Rust stains: Apply a commercial rust remover or oxalic acid solution. Let dwell, scrub, rinse thoroughly.
• Mold and mildew: Apply diluted bleach (1:10 ratio) to unsealed concrete. Let sit 10 minutes, scrub, rinse. Use hydrogen peroxide on sealed concrete.
• Paint: Use a paint stripper appropriate for concrete. Follow product instructions carefully.

Sealing Concrete Floors

Sealing is the single most impactful thing you can do for concrete floor maintenance:

• Sealer fills the pores and creates a barrier against staining, moisture, and abrasion.
• Sealed concrete is dramatically easier to clean than unsealed.
• Reseal every 1–3 years depending on traffic and sealer type.
• Choose the right sealer for your use: penetrating sealers for natural look, topical sealers for gloss finish.

Final Thoughts

Concrete floors are durable and relatively easy to maintain when properly sealed. Daily sweeping, weekly damp mopping with a pH-neutral cleaner, and periodic resealing are the foundation of concrete floor care. Unsealed concrete requires more effort and should be sealed as soon as possible for easier long-term maintenance.
