A pre-mixed, ready-to-use, mild acid solution. Removes dried Portland cement grout haze and mortar residue from tile, concrete and masonry.
White vinegar works well on most grout haze but ideally should be diluted. Try 10 parts water to 1 part vinegar first and go from there but check on an unobtrusive area first.
We use Muriatic Acid diluted to clean bricks. In a 5 gallon bucket add 3-4 litres of water and 1 litre of acid on top. Don't add 1 litre of acid and then the water or you will nutralise the acid. Once you apply it to the grout haze you will see it bubble and foam as the acid breaks down the cement.
Ideally, the final wipe-down will take place after the grout has been allowed to cure for 24 hours. However, grout haze could still potentially be removed within a few days.
Once you've activated the micro-scrubbers inside, your Magic Eraser is good to go. Start by swiping it firmly across the desired surface. In just a few swipes, you should start to see grout messes and buildup begin to disappear!
You can do this by gently applying a spray of water across the mortar or using a wet rag to apply water across the stains. With a hammer and chisel, gently tap the chisel at an angle against the mortar. Remember not to force it, as this can damage your brickwork.
If the grout remains on the surface of the tile for more than 30 minutes, it is much more likely to result in grout haze. In some cases, grout haze may form after a few days.
Our hack to cleaning this is very simple! Take 220 grit sandpaper, add water, and rub it in circular motions on your cement tile. You'll soon see your grout haze lift right off.
Try to remove the cement stains or mortar residue with one part vinegar and one part warm water. Then you brush this solution onto the surface. Leave to absorb and then rinse with clean water. Depending on the type of surface, you can remove cement stains and mortar stains with sandpaper or a scraper.
You can easily remove mortar from your tile flooring with a little elbow grease and the right tools. Be sure to work in small sections and use a putty knife or chisel to scrape away the mortar. Once you've removed all the mortar, sweep or vacuum the area to remove any debris.
Mistake: Applying too much adhesive can cause tiles to slip or ooze adhesive through the joints. Too little adhesive can lead to weak spots and failed adhesion.
Grout haze remover is going to be acidic in order to get at the stubborn debris. The best ingredient you can find on that list is muriatic acid (aka hydrochloric acid) which is strong and tough on grout haze without harming the tile when used correctly.
Rubbing Alcohol: Just mix rubbing alcohol and water in a spray bottle, spray directly onto grout and let sit for 10 minutes. Then wipe away. No scrubbing needed!
Is hydrogen peroxide safe for grout? Yes, hydrogen peroxide is a natural neutral cleaner that is safe to use on grout. Hydrogen peroxide and baking soda produce oxygenated bleach, which is highly effective for cleaning grout.
The resulting haze cannot be removed with water alone. Grout haze remover is a specialty commercial cleaner that helps to get rid of grout haze—especially in substantial or difficult cases. Grout haze remover comes in different formulas both cement-based and non-cement-based grouts.
Once the grout has started to harden (20 to 30 minutes), begin sponging. Don't use just any sponge, especially one from the kitchen; choose a “hydrophilic” sponge. Make sure the sponge is damp, not wet, and sweep diagonally across the face of the tile and wipe the grout off the tile surface.
Different ways to remove grout haze
If this does not work completely, use a mixture of 50% water and 50% vinegar. The acid dissolves the lime residues that make up a grout haze. Special grout haze removers, which you can buy in the tile shop or hardware store, work on the same principle.
We recommend that you wash the surface with DETERDEK Grout Haze Remover. See the instructions on the product label for the appropriate dilution and application instructions.

To get that perfect clean use Hydrochloric acid , diluted 2 parts hydrocloric acid to 10 parts water . Lay the bricks together with the face you want to clean face up soak them with acid water mix using a sfiff bristled plastic broom a couple of times until clean .
Known as grout haze, this smeared white coat is a common aftermath for many tiling jobs, and when left untreated, it can be a tricky and persistent stain to get rid of. Fortunately, it's not a permanent smudge, and can be readily removed with the right know-how and knowledge.
One of the workers there suggested that a solution of distilled vinegar and warm water will cut right through the haze. I loved the sound of the chemical free fix. He helped us find some mops and buckets, a scrubby for any stubborn areas and they even carried the vinegar.
