In contrast, glycolic acid-based concrete remover formulations are: More efficient at penetrating and loosening concrete. More highly effective calcium-complexing agents. Significantly less corrosive than hydrochloric acid-based removers on most surfaces.
Phosphoric acid, trisodium phosphate, and muriatic acid all dissolve concrete. Phosphoric acid is the most common acid used for this task. Only use muriatic acid after removing all other acids.
The inorganic compounds which are useful as concrete dissolvers generally include inorganic acids such as hydrochloric, phosphoric, hypochlorous and carbonic acid. Salts of these acids and alkalies such as sodium-hydroxide, sodium bicarbonate and ammoniumsulfate are also eifective.
Knockout 100™ is the most powerful technology developed for the removal of concrete from Ready Mix trucks and other concrete equipment. Although it is safe on most common materials such as iron, steel, plastic, rubber and vinyl, Knockout 100 quickly eats through thicker accumulations of dried concrete.
Muriatic acid is a powerful cleaner in that it can remove multiple kinds of stains at the same time. Removes paint splatter. Paint splatter on concrete gets more difficult to remove as time goes on.
Scrub the acid solution: Once the solution is applied, lightly scrub it into the concrete with a push broom or long handled scrub brush. This helps to create a uniform etch of the concrete. Let the solution sit from 2 – 15 minutes while it continues to fizz and bubble.
Over time, it can destroy concrete as the acid weakens its structure. This will cause scaling, pitting, peeling, and cracking. If the acid wash gets into the soil, it will evaporate on the surface but remain beneath the surface (just like it does with concrete).
Easily remove concrete from your tools and equipment with Mean Klean 22 oz. Concrete & Mortar Dissolver. The advanced liquid formula dissolves and physically breaks down concrete by attacking the Portland cement, eventually reducing it to mush that is easy to clean off with a hose or pressure sprayer.
Tool #1: Sledgehammer + Pry Bar
Sledgehammer is the best tool to use if the slab of concrete is three inches thick or less. Dig at the base of the slab to find the bottom. If the distance from the bottom to the top is at or under three inches, hammer away!

AKA Dexpan Expansive Demolition Grout, Rock Splitting Compound Chemical.
Concrete Dissolver Cleaner CDCCA-1000, Cement Remover Chemical in India. Concrete dissolver cleaner chemical is the best chemical for removing dry hard concrete waste. It is also known as Cement remover chemical.
HYDROCHLORIC ACID - also known as muriatic acid or spirits of salts - is a concentrated, fuming acid suitable for all technical grade applications. It is most commonly used for brick cleaning or concrete etching because of it's ability to dissolve hardened cement quickly without attacking hard stones or brick.
Muriatic acid will quickly liquify most metallics, consisting of iron, copper, and light weight aluminum. It can easily additionally diffuse cement, rock, mortar, as well as grout. Additionally, muriatic acid will take out blemishes from rugs as well as cloth.
Sulfuric acid and concrete don't mix. Concrete can stand up to a lot. Sulfuric acid reacts readily with concrete and dissolves the surface area it comes into contact with. The amount of time permanent damage takes depends on the concentration of sulfuric acid.
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.
The trick to breaking up concrete is to dig underneath the slab before hitting it with the hammer. Undermining the concrete eliminates its external support, making the material much more vulnerable to cracking through and breaking off.
Clean cement with WD-40
Removing these discolored formations is a job for chemical products such as WD-40 Multi-use Product. It is safe to use on a metal object because it consists of weaker acids. Spray the chemical on the cement formations and leave it for some time. Then scrape them off using a putty knife.
Contractor's strength Muriatic Acid helps prevent cloudy water due to water hardness. Helpful for acid-washing your pool. Available in 2 one-gallon pack.
Any concrete that is not properly neutralized will begin decomposing immediately. It may take time for the damage to reach the surface where you can see it, but it is happening and is usually irrepairable.
Muriatic acid is a form of hydrochloric acid, which has a pH of about 1 to 2. The only differences between hydrochloric acid and muriatic acid are purity—muriatic acid is diluted to somewhere between 14.5 and 29 percent, and often contains impurities like iron.
Muriatic acid is strong enough to etch concrete, but it can also cause severe injury and/or damage property when used improperly. Always wear protective clothing, rubber gloves, boots and goggles or a face shield when handling acid. Avoid breathing acid vapors.
