To use vinegar on brick mortar would be too weak. You’ll need to use hydrochloric acid and step it up. If you look for this acid at a hardware store, building supply store, or home center, it will likely be listed as “muriatic acid.” This corrosive acid is highly harmful when taken directly from the plastic jug.
Will vinegar get rid of mortar?
Other acids can react with the alkaline substances in the mortar to dissolve them. Your kitchen’s white vinegar will also function to some extent. You have to discover an acid that falls between vinegar and hydrochloric acid and removes mortar accumulation effectively.
Bricks would vinegar harm them?
Q. I’ve been hand-pulling weeds for four days straight, but I’m only halfway done! Even though I’m quite concerned about the safety of my outdoor cat, perhaps there comes a time when one has turn to chemistry for assistance. Any recommendations?

My most recent residence had a brick walkway. Unfortunately, there isn’t any concrete between the bricks, and weeds are sprouting up everywhere. You mentioned flame weeders, which sound much more advantageous than pesticides. Where can I get one?”
Terri in Telford, Pennsylvania
I’ve been looking for the device you claim to use to burn weeds, but I can’t seem to find one. Would you kindly cite your sources?

To get rid of weeds in the grout spaces between our pavers, I was considering using pure acetic acid. Can flagstone be harmed by 20% vinegar?
—-Haia in Reading, Pennsylvania
I often spend an entire Saturday and a lot of knuckle skin clearing my patio by hand. However, even if I am successful in removing the roots, they will reappear in full force within a month. I’ve read about remedies that call for boiling water, salt, and vinegar. Naturally, Round-Up is not an option. What are the simplest methods for obtaining these weeds?
Tom in Norristown, Pennsylvania
A. Yes, the year for weeds has been bad. Everything I planted in my garden was destroyed by the recent historic heat wave, but the weeds loved it!
Yes, it may be particularly bothersome when weeds grow in the spaces between bricks, pavers, flagstones, and other similar materials in paths. Although Terri in Telford laments her lack of mortar, walkways are a must because if those gaps were shut up, the entire structure would crumble under the strain of heat and cold.
Vinegar WILL harm the surface of any paver, brick, flagstone, or concrete, therefore never use it on any of these materials. Salt is the same. Additionally, the frequently advised “boiling water” will harm your surface. Ever try to transport a sizable pot of boiling water? With each step, it sloshes more ferociously until it spills over the side, burns your palm, causes you to drop the pot, and scalds your legs, feet, and tootsies.
Sprays made of herbicidal soap are much safer and more efficient at getting rid of weeds in walkways. They smother their target pest with a soap-bubble coating, similar to insecticidal soaps, and leaving your walkway spotless. During a dry spell, thoroughly soak the weeds in soap at the height of the day, and they will wither and die.
And sure, my go-to flame weeder is one of my favorite gardening tools. I use a device called BernzOmatic’s “Outdoor Torch”; to use it, you put a propane bottle the size of a camp stove into one end of the long wand, press the igniter, and a small, endearing flame emerges from the other. Wait for a dry period, then wave the flame over the tops of the weeds to cause their hydration and eventual death. You can get one from any hardware or home supply store, and many of them have them in stock right now. You can also order directly from BernzOmatic by contacting their toll-free number at 1-800-654-9011 (they don’t sell online).
Similar products are sold by a variety of other businesses. Canadian company Rittenhouse, for example, offers a cheaper flamer and a more expensive one dubbed the “Infra-Weeder Dandy Destroyer” that employs intense radiant heat rather than an open flame. It has a spike on the end that is intended to cook dandelions to death, but it also appears like it would work nicely in the cracks between pavers. (These two devices use the same tiny, single-use propane bottles as the BernzOmatic.) Additionally, Rittenhouse formerly had a “Infra-Weeder” with a flat head. HEY! I was told that! that was exclusively intended for walkway usage, but it appears to have been replaced with a similar-looking, extremely costly professional one that costs over $1,000 instead of a few hundred dollars and uses a large refillable propane tank sized for a gas grill.
If you decide to use flame, take cautious not to ignite yourself, nearby leaves, or nearby vegetation. The leaves and brush shouldn’t be an issue on pavers, but once you have one of them, you might as well use it everywhere. So, if you decide to go off with your flamethrower, have a hose-wielding companion close by.
Alternately, keep your pyromania to the patio and use a vinegar or soap spray to get rid of weeds in flower beds and roadways. Because it is technically incorrect to refer to vinegar as a herbicide, I used the word “quote.” The EPA has determined that vinegar is safe to use and exempt from pesticide rules in their slightly less-than-infinite wisdom, but only as an inert material, despite the fact that vinegar is very much the opposite of inert. However, the government insists it is, and if you disagree, they will penalize you and detain you for the rest of your life at airports.
10% and 20% acidity “high strength” vinegars are available in select retail stores and online, however they cannot be labeled as herbicides or given usage instructions due to legal restrictions. The best they can do is call them “horticultural vinegars,” with the implicit implication that you will use them to clean your pruning equipment instead of awful bleach, wink, wink.
Because of this, the several organic herbicides that are already appearing on store shelves each list a different active component; clove oil is a common option. Most also include a vinegar with an average acidity of 8%, however just as one of its “inert” constituents. These are quite effective weed killers, much like herbicidal soaps; just be careful not to spray them on desired plants or your lovely patio.
Can vinegar be used to clean brick?
Brick may be cleaned indoors or outdoors with vinegar. It works particularly well on efflorescence, the salt crystals that accumulate on the mortar and have a chalky white color. Using a scrub brush and a solution of 1 part white vinegar to 5 parts water, the efflorescence can be removed.
How do you remove bricks’ mortar?
I was handed a stack of bricks from a neighbor’s property. They will be put to use in the median strip in front of my property, which is located between the sidewalk and the curb. I need to remove the old mortar that is adhered to the sides of many of the bricks. Can you offer a different approach to the chisel-and-hammer technique suggested at my neighborhood hardware store? How can I get rid of the bricks if they can’t be cleaned up?
A: It’s fantastic that you’re getting ready to give those old bricks a new home. We like the way old brick looks better than new, but we also appreciate that you are making good use of the material.
You still have a lot of work to do, but don’t worry—not it’s difficult—just time-consuming. Additionally, it’s unlikely that you’ll be able to rescue every one of your neighbor’s old bricks. Several will inevitably be damaged beyond repair or fall apart when the mortar is removed.
The bricks should be soaked in a muriatic acid and water mixture as your initial step. This will cause the hardened mortar to become sufficiently pliable to be removed with a hammer and cold chisel. The alternative, and the approach we recommend, is to saw the mortar off using a circular saw equipped with a blade covered in diamonds. When working on smaller assignments, Ed, Kevin’s father-in-law and a master mason, cut bricks using this technique.
Masons have been removing mortar residue from brick and stone for years by using muriatic acid, commonly known as hydrochloric acid. Any project leaves a gray mortar coating on the bricks at the conclusion. The Portland cement in the mortar is emulsified by muriatic acid, making cleanup simple. It is diluted with water, typically 10 parts water to 1 part acid, rather than being used at full strength. The label includes instructions for safe handling and dilution.
To begin the task, set up a work space. To prevent any acid solution from seeping into the ground, spread out a heavy canvas or plastic drop cloth on the surface. Create a table or bench using some sawhorses and a piece of 3/4-inch plywood.
Lay out your tools next. If you decide to use a power saw, be sure to choose one that is lightweight enough for you to handle for extended periods of time without discomfort. Use a power source that is protected by a GFCI (ground-fault circuit interrupter) outlet as well. Since you’ll be working near water, this will shield you from electric shock.
In a 5-gallon plastic bucket, combine the acid solution in accordance with the manufacturer’s instructions. Always pour the water in first, followed by the acid, to avoid any potential eruption or spillover. As many bricks as the bucket can handle without overflowing should be placed in it after it is about halfway filled. Verify that the bricks are completely submerged.
Pull them out of the bucket and set them on your worktable after letting them soak for about 15 minutes. While you clean the soaked bricks, add more bricks to the bucket to soak.
Remove the old mortar from the soggy bricks with a saw, chipper, or chisel. After removing the majority of the mortar, use a wire brush to thoroughly scrub the bricks to remove any remaining mortar. Repeat the process with the cleaned bricks stacked in a pile. All of the salvaged bricks will be cleaned and prepared for their new home before you know it.
You can easily sell or give them away if, for whatever reason, you decide you can’t utilize them or don’t want to finish the task. We bet they would be gone in less than a day if there was a Craigslist ad.
How can dry concrete be removed from brick?
It’s recommended to remove the bigger portion of the concrete using other techniques because large chunks of concrete might be challenging to dissolve. If the concrete is on glass, wood, or plastics, avoid using force or mechanical means since this will harm the surface underneath. It is okay to use a cold chisel and hammer to gently tap at the bigger portion of the concrete to clean brick.
To somewhat lubricate the concrete before doing so, try soaking it in hot, soapy water. Additionally, if the brick or stone is exceptionally smooth and slippery, this works wonderfully. It is preferable to slide a flexible metal putty knife behind the spill and pry it away from the surface in this situation. This frequently leads to an extremely tidy and enjoyable removal.
Which brick cleaner works the best?
To preserve the best long-term beauty and integrity of the faade, certain essential measures can be implemented into the brick cleaning process. Your new home will look finished and the brick’s color will be enhanced by carefully cleaning the brick.
Identify the right cleaning solution
Choosing the correct cleaning is crucial because there are numerous masonry variations and a large range of imitation masonry options available today. For instance, some concrete bricks are designed to resemble clay brick. However, you risk damaging the concrete brick if you clean it like a clay brick. Make sure the cleaning process is completely understood by your team.
Common dirt can be removed in a variety of ways, but dried mortar cannot be removed from brick without the use of an acidic cleaning. It’s crucial to choose a cleaner that can remove efflorescence, filth, and mortar all at once. However, not every cleaning technique produces the same outcome. Muriatic acid is frequently used by builders and contractors since it is slightly less expensive for clean-down. The brick may become stained by muriatic acid since different batches might differ substantially in strength (even before the diluting procedure) and impure content.
Instead, pick a cleaner designed for new construction that contains buffering ingredients to save the mortar joints and bricks. Even though specifically designed cleaners could cost a little bit more per square foot, this cost is insignificant in comparison to the potential costs of burning, etching, or permanently defacing the stonework or jeopardizing your reputation.
New construction cleaner checklist:
1. Pick a cleaner that has been “buffered” for maximum efficiency. The brickwork will be left clean and uniform with no acid burning or streaks after using a buffered cleanser, which won’t lead to the deterioration of mortar joints.
2. Only choose goods made by a supplier who offers trustworthy technical and product field assistance.
3. When possible, ask the producer of the brick, block, tile, or mortar for a recommendation, or speak with your nearby distributor of building supplies.
Clean brick properly
Start by having a clear idea of the type of brick and mortar and degree of soiling to choose which cleaner is best for the job. Test the least aggressive dilution ratio advised by the manufacturer before to starting the cleaning process, and make adjustments from there.
Prior to using the cleaning solution, plan to pre-wet the surface with cold water. The substrate must be completely saturated before the cleaning solution is applied. This step is particularly important since failing to do so will result in the cleaner being absorbed into the pores of the brick or masonry, which can etch, burn, and produce additional discoloration.
To remove large mortar chunks, use non-metallic chisels, wood scrapers, or discarded brick. Remember to cover nearby surfaces like doors and windows with plastic sheeting or strippable masking to protect them.
Brick can be cleaned most easily using a bucket and brush, and when done correctly, it produces results that have stood the test of time. For the majority of masonry cleaning tasks, a natural fiber acid brush is advised. It is advised to pressure wash with a flow capacity of 1000 psi and 6–8 gallons per minute.
Start at the bottom of the wall and work your way up, keeping the lower portions moist the entire time to avoid streaking and scorching as well as to stop runoff from permeating the brickwork. To get rid of all of the cleanser, thoroughly rinse the wall.
Cleaning a structure correctly the first time is always more economical than making numerous unsuccessful attempts and running the danger of damaging the brickwork. Following these guidelines will reduce the margin for mistake, leaving your projects looking stunning, and assure the masonry’s long-term stability.
