I started in power washing as a residential washer. It was my immediate plan to concentrate on siding washes and deck and fence restoration, with a little bit of commercial work in fleets and some flat work. Writing those first two sentences reminds me how little I knew about the pressure washing business starting out, which reminds me why I am writing these articles in the first place: People need better inside information to decide whether or not to enter this field.
I soon found that I was doing a low but fairly steady number of residential building washes, and a large number of deck restorations, and an even larger amount of commercial flatwork. After a few years learning my trade, and better understanding the requirements of my potential customers, I began to land some commercial building washes, mostly warehouses, especially precast concrete.
Precast concrete warehouses are easily cleaned, depending on what contaminants are on them, but there are some significant digressions from residential pressure washing methods you should be aware of before you bid or start on cleaning one.
First off is the question of scale. When you have determined the best removal method for the soil on any building, you then have to estimate how much you will need. I have found that it is good to pad my estimate a bit on commercial buildings. It seems that they always take a bit more chemical than the surface area calculations would suggest, especially in surfactant. This is probably due to the sheer height of the average warehouse, and to the porosity of the concrete substrate. More cling to keep the chemicals working on the surface longer is a definite plus.
Also plan on moving slowly, more slowly than you might believe necessary. The tall, unbroken walls of warehouses dry quickly in any breeze, and unlike most residences, there usually is no landscaping or nearby trees to provide windbreaks or shade. Both of these factors increase the drying speed of your solution, and require you to rewet to keep the chems lively and working.
Another factor the increased height will affect is the need for a lift. No matter what method you use to apply chems to a residence, you will probably need a lift to do a good job on a multistory commercial building. This is because the commercial building is much more likely to have large structures protruding from the walls high above the ground, and these structures often prevent even the best chemical shooters from having a direct shot at large areas of high wall. This causes uneven or non-application of your mix, and can increase chem. consumption and overspray to unacceptable levels.
A lift will get you right up near the wall you are working on, allowing you to shoot highly concentrated chemicals right where they are required. It will also allow you to avoid many of the ground-level obstacles such as loading docks, break tables, dumpsters, and parked vehicles that can interfere with your ability to evenly apply tour mixture where it is needed.
With a lift comes the requirement for at least one assistant. On a residential job it is easy enough to mind your own hose, and machinery, since you are rarely far from the rig and getting to it requires only a quick step. In a man-lift, coming down may be an involved operation, and a ground man adds a level of safety as somebody who can summon assistance, or tend the hose so that the lift operator can concentrate on the job at hand.
In fact, when operating a lift, a second person in the lift can be helpful to operate it in tight areas as the person on the wand concentrates on cleaning the substrate. In any event, a person to tend to concerns on the ground is a necessary part of most large commercial pressure washing.
There is another personnel related issue present in commercial cleaning that sets it apart from residential work: People trying to do their jobs in and around the building.
I recently was cleaning gutter-troughs on a five-story warehouse, when a heating and air-conditioning tech came and set up directly below my lift. He was there to start inspections and maintenance, and because he had always begun the job at the specific machine I was working over, he was going to start there that day as well.
It only took a few moments for my ground guy to show him how unpleasant that was going to be for him, and he realized he was just used to starting where he had. He happily enough moved to a unit around the corner, and we never saw one another all day.
Employees of the property owner can also be in the way as they try to get their jobs done, and sometimes can be openly hostile. I have found it best to have the managers prepare them ahead of time, and to try to arrange to not work in the same areas I need to work in. It sometimes helps to schedule the work for off-hours, or to schedule the job to minimize conflict. For instance, if the dock area is busiest at one time, and largely unused at another, try working in the dock area during the slower times. Common sense goes a long way.
There are numerous differences between commercial and residential work, but few that are not easy to handle if you just prepare ahead of time. As in most aspects of your pressure washing business, a little planning will always save headaches.

I worked in the carpet and upholstery cleaning, installation and repair business for about 15 years and during that time I had the opportunity to use some high power cleaners for removal of spots stains and general dirt. I have also used 3 different types of cleaning methods shampoo, dry cleaning and water extraction or steam cleaning. Today I would like to share my thoughts on each one.
Shampooing your carpet is probably the oldest method I know of to use. I am sure there have been others but then I am only 42. For some fabrics like wool and some moisture sensitive cottons shampoo provides a moist form of cleaning and can help minimize color bleeding and extreme shrinkage. A rotary machine with a soft brush is used. The shampoo is applied to the carpet through a sprayer and the rotary machine is run back and forth across the carpet.
Dry cleaning of carpet and upholstery really became all the rage in the 80's. The guy who created Chem Dry is said to have actually patented the chemical he created for carpet and upholstery dry cleaning. He then trained others to use the process and then sold them franchises with the rights to use the chemical. A rotary machine is also used, but with a cotton bonnet instead of a brush. The carbonated chemical is applied to the carpet through a sprayer, is allowed to sit for a few minutes then the rotary machine is moved back and forth across the carpet. The cotton pad usually dampened picks up the dirt that is loosened by carbonated chemical. The carpet usually dries in a couple of hours.
The method I used the most and liked the best was water extraction. Through a high pressure pump hot water mixed with the correct amount of cleaning chemicals is injected into the carpet to break down dirt embedded in the fabric. The water jet is attached to the head of a cleaning wand that the vacuum runs through. The chemicals, water and dirt are removed immediately with each pass of the tool. When the equipment is used properly the carpet can begin drying right away and usually will be completely dry in 4-5 hours.
Each of the methods I have outlined above have their positives and negatives.
I would like to leave you with one thought. If I put soap in my hair and I do not rinse it out what do you think will happen when it dries? The shampooing and the dry cleaning offer now way to completely remove the chemical they scrub down into your fabric. It is like washing your laundry and not rinsing the soap out. With water extraction the chemicals and dirt are flushed out with the vacuum and removed to a holding tank.

A stained carpet can be a huge chore to clean, but professional cleaning is expensive, and even renting a carpet cleaning machine can really rack up the cost. If you're looking for a cheap yet effective way of cleaning a stained carpet with cleaning products that can be found relatively easily, then read on. Here, we'll go over a few tips that will help take out a variety of stains, as well as how you can keep the cost of cleaning a dirty carpet down significantly. These tips can also be used for upholstery cleaning, such as for furniture or even in a vehicle.
Stained carpets are a tricky business, because a stain that is not properly taken care of can easily become permanent. Each type of stain will require a different cleaning technique, and not every technique can be applied to every type of stain. Carpet cleaning is primarily accomplished using one of two primary tools: vacuums and cleaning products. Keep in mind that the severity of a stain can be dramatically reduced by blotting the spill with a paper towel, sponge, or other absorbent immediately after the fact. Make sure to pat the area of the stain, not rub, as this can actually push whatever is staining into the carpet further.
Vacuums are actually more effective than you might think at carpet cleaning when it comes to stains. Depending on the material that has stained the carpet, a vacuum may or may not be as effective, however. Anything that hardens over time, such as mud, food, or even juice, can be in large part removed by vacuuming. Even milk that has been spilled can be picked up by a vacuum once it has dried, although in many cases it is not practical to leave a substance on a carpet long enough for this to occur.
In order to get the best results out of carpet cleaning, a vacuum should be used in tandem with cleaning products. These can come in the form of specialized shampoos, various type of cleaners for particular stains (such as pet messes), and so on. There are many types of eco-friendly cleaners that will not create dangerous waste, the ingredients of which are largely biodegradable, making them safe to throw away with vacuum bags. Using a cleaning product, allowing that product to soak in and absorb the stain, and then vacuuming it away is the most effective cleaning.
