The best concrete cleaners can lift dirt, grease, and grime. But not every concrete cleaner works for every surface or every type of stain. While you can use a general concrete cleaner to wash away dirt, you’ll need an oil-removing product to eliminate set-in grease stains.
You’ll also need to use a more mild solution for polished and epoxy-coated concrete floors.
Here’s a look at the best concrete cleaners, including eight commercial options and two DIY concrete cleaners.

What to Consider Before Buying a Concrete Cleaner
While it’s tempting to grab the easiest-to-use or least expensive product, choosing one compatible with your type of concrete is essential. For example, if you’re cleaning polished concrete floors, avoid acidic cleaners and go for something PH-neutral.
Here’s a breakdown of the types of concrete cleaners:
- Acidic cleaners – great for removing stains but can damage surrounding plant life and polished concrete.
- PH neutral cleaners – these cleaners are mild and appropriate for indoor and polished concrete
- Alkaline cleaners – most degreasers have an alkaline base, which is best for cleaning oil and grease spots
- Enzymatic cleaners – capable of lifting stains and bacteria caused by organic matter
