Does white vinegar clean concrete?

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.
Does bleach remove stains from concrete?
Bleach effectively removes many stains, deodorizes and kills mold and mildew when used properly. For tough stains or dirt, scrub the concrete with a scrub brush. Allow the bleach solution to sit for five minutes. Empty the bucket, rinse it out and fill it with clean, warm water.
Can you use bleach to clean concrete?
For lightly soiled concrete, you can remove dirt by using bleach mixed with water. Add 1/8th cup of liquid dishwashing detergent to the solution and pour it into a spray bottle. Spray the solution onto the surface, and let it sit for a few minutes. Scrub with a nylon-bristled brush.
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.
