Acid Staining
Acid stains are a reactive coloring process that penetrates into the porous concrete surface. This is probably the most permanent of all coloring options but is usually limited to eight colors.
There are two types of concrete stain to choose from: acid-based and water-based. Acid-based formulas for are long-lasting and resistant to fading. They react chemically with the concrete to create a permanent chemical bond. This means it will not peel or chip and will help produce a natural-looking finish.
The Liquid peroxide cleans, refreshes, and brightens concrete, tile, and grout without leaving watermarks or residue in contrast to other cleaning chemicals. Powdered peroxide-based formulas are generally high-performance alkaline, tile and grout cleaners and degreasers that are made for use on heavy-duty concrete.
In other words, water-based stains perform by flowing into the concrete pores and bonding with the cement, but they do not chemically alter the concrete itself. This means that by definition they are not permanent — if you don't apply a sealer, they can wear away.
Products, such as vinegar, sandpaper or a scraper, are useful as an emergency solution for removing cement residues but they are not always terribly effective. They can also damage the surface. With HG tile cement grout and mortar remover you remove cement stains quickly, safely and effectively.
Interior Concrete Floors:
Clean with water. Use a mild detergent as needed. Such as Dove or Ivory dish soap. Do Not use Dawn, Simple Green, Ammonia or harsh cleaners as they will work to damage and even strip the wax.
Pressure washers
Then add detergent to your pressure washer and begin spraying. Move at an even pace and keep the nozzle at the same distance from the surface of the concrete at all times to ensure that no streaking occurs. Allow the detergent to sit on the spot for five to ten minutes before rinsing for best results.
Whether your patio is sealed concrete or cement, or even sealed concrete pavers, a bleach and water solution makes it easy to clean away built up soil, stains from leaves and pollen, mold, mildew and algae.
Will Vinegar Damage Concrete? Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.
