Mix up a warm water and dish detergent solution. The only trick to this step is that you cannot have bubbles in the mixture so keep mixing until all the bubbles disappear. Set it aside for now. Using one of your stiff brushes, start wiping it across the mortar that you need to remove from your manufactured stone.
Vinegar can only dissolve smaller mortars. You will need a more penetrative method to clean all those old and large-sized mortar residues. You might need a large amount of vinegar to dissolve a medium-sized mortar cleanly.

How to Remove Dried Concrete. Applying a concrete dissolver is one tactic used to soften old mortar on masonry tools, equipment, and vehicles.
Water erodes the mortar that holds the bricks or stone together, which destroys the integrity of the structure. Water will also degrade the bricks themselves. Erosion contributes to this, but if you live anywhere with freezing temperatures in the winter, the damage will be more severe.
Add water to a little bit of powdered laundry detergent until it forms a thick paste. After the cement finishes drying, wet the area and apply this paste using a soft brush. Scrub the cement using this paste and clean it with water afterwards. Repeat the process until the cement is all gone.
We never recommend washing lime mortar joints with any type of acidic product. If you need to remove mortar smears from masonry simply use a green scouring sponge and water. Most smears are easily removed with the method within 24-48 hours after pointing.
Mix warm water, a few drops of Dawn, and two tablespoons of Borax in a spray bottle. Spray the mixture on the affected mortar. Scrub the area with a bristle brush. Repeat until clean.
Your first step should be to soak the bricks in a solution of muriatic acid and water. This will soften the cured mortar enough to allow removal via the tried-and-true method of hammer and cold chisel.
Super Quick Concrete Dissolver is a liquid compound specifically formulated to dissolve built up cement on tools and equipment associated with the concrete ready mix industry. The highly concentrated formulation is compounded to maintain sufficient acidity to dissolve harder cement.
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.
An easy solution is to let the mortar dry and, at the end of the project, clean the mortar off the wall with muriatic acid. You can apply these same techniques to most masonry projects involving cement products. Muriatic acid is also called hydrochloric acid, spirits of salt, or acidum salis.
Vinegar does not dissolve concrete itself but can degrade the cement that binds concrete together. As a weak, dilute acid, vinegar will cause only minor damage to concrete but can take the shine off polished surfaces. It can, however, be used to remove small amounts of cement from tools.
If you're taking on a small mortar removal job, a hammer and plugging chisel may suffice. They're perfect for taking out mortar from a small area or for work on a small masonry project. Again, for DIYers, just be careful using a hammer and chisel because you may end up damaging the brick.
You can use Simple Green Oxy Solve Concrete and Driveway Cleaner to clean a concrete patio with or without a pressure washer. It removes oil, grease, grime and most stains and discolorations. Its biodegradable formula is safe for lawns and pets.
Vinegar is the best bet for removing the lime residue on the stone faces - you just have to keep at it.
Plugging chisels, masonry chisels and old hacksaw blades used in conjunction with a club hammer will easily remove the mortar. Never use chisels that are wider than the mortar joint as this may result in damage to the adjacent masonry.
