As a trusted pressure washing company in Maryland, Griff’s Services is proud to always provide our customers with the answers they have to common concerns about what we do. One of the biggest questions our clients have is the environmental impact of power washing. While we do use minimal amounts of certain cleaners to help ensure the exterior of your home or concrete driveway is effectively cleaned, there is no risk to you or the environment. Here’s what you need to know about the chemicals used in pressure washing.
Sodium Hydroxide (Lye)
While it sounds like a scary chemical, sodium hydroxide (lye) is actually found in numerous products you already use on a daily basis, such as soap and many household cleaning formulas. It is widely known as an effective degreaser that works well on metal, glass, and other materials.
Sodium Hypochlorite (Bleach)
In certain low amounts, bleach is used as part of the pressure washing process. Generally, any amount used is highly diluted with water to prevent damage to our equipment or safety concerns. This chemical is generally reserved for situations where there’s mold or mildew present, as it keeps it from coming back.
Just like you would use it around the house, ammonia can also be utilized during pressure washing. In most cases, it is just used for glass or stainless steel. But it is usually a secondary option compared to other cleaners used in power washing.
Another option is citric acid. This type of cleaner is what you usually see on home improvement store shelves for use in residential pressure washers. It is especially good for removing stains and rust from concrete, wood fencing, decking, and more. It is considered one of the safer options for removing stains from driveways.
Most pressure washing companies start with one of the previous methods and finish with oxalic acid. While it is a little more caustic than some other choices, it is great for getting deep stains and discoloration from porches, patios, and other concrete surfaces.
Is Pressure Washing Safe?
Professional power washing is an extremely safe way to improve the exterior of your home while protecting building materials from bacteria or fungal overgrowth. The use of chemicals are designed to act in addition to the higher pressure of the water, which is why the combination works well.
It is also important to note that each project is handled on an individualized basis. Our expert team will assess your building’s exterior for any presence of mold, bacteria, or algae growth, plus any staining issues you’re currently having. Then, we will decide on the best chemical or solvent for your particular situation.
And, as always, if you have questions about what we use to clean specific surfaces, please do not hesitate to ask.
