Does white vinegar clean concrete?
Yes. Vinegar makes a great cleaner for stained concrete floors. Because of its acidity, you should dilute it 50/50 with warm water to avoid damaging the floors. However, you can use small amounts of full-strength vinegar for touch stains, followed by a quick water rinse.
Will baking soda damage concrete?
When washing concrete, be wary of using any strong chemicals, particularly any acid-based cleaners—these can damage concrete. Instead, use gentle washing agents such as baking soda, dish soap, and water. There are several methods you can try to get your concrete looking like new again.
Will straight bleach harm concrete?
When applied to concrete, bleach does not harm the sturdy material. It also disinfects concrete. When using bleach, work in a well-ventilated area because the fumes from bleach can be overwhelming. Depending on your cleaning project, you might combine the bleach with detergent, dilute it with water or use it straight.
Does WD 40 remove oil stains from concrete?
WD–40 is an effective grease stain remover. In some cases, WD–40 can remove oil stains from concrete. However, it isn’t as effective as other methods and depends on how old the stain is. If you have it on hand, you can give it a try by spraying it on the stain and letting it sit for 30 minutes.
How can I make my concrete white again?
Apply vinegar or bleach to the discolored areas. If you use vinegar, do not dilute it. Pour it onto the concrete and scrub it into the surface with a scrub brush. If the discoloration starts to fade, repeat until it disappears completely.
Can urine soak into concrete?
Concrete is actually porous like a sponge. If liquid is allowed to sit for a period of time, it will absorb most anything. This is why it’s hard to get stains out of concrete. When urine is introduced to concrete and allowed to dry, the uric acid crystals present in urine bond tightly to the concrete.
How do you get water stains off of concrete?
In most cases, a mildly acidic cleaner combined with some scrubbing can remove these stains without etching concrete. Fill a spray bottle with equal parts white vinegar and water. Spray the water spots thoroughly with the vinegar solution, saturating them completely. Let it sit for five minutes.
How long does stain last on concrete?

What are black stains on concrete?

What is the black stuff on my concrete driveway?
If you have greenish-black stuff on your concrete patio, it’s probably mold, mildew, or moss. Damp or moist conditions from rain or humidity can encourage mold and mildew to grow in those nooks and cracks of concrete pavers or bricks.
What kills mold better bleach or vinegar?

In fact, recognizing the bleach as a ‘threat,’ the mold will grow back even stronger.” When bleach is used on porous surfaces like drywall or wood, mold membranes will move deeper into the surface to avoid the chemical.
