Soft Washing vs Pressure Washing FAQ



Frequently Asked Questions at Alblaster
The soft washing process uses detergent instead of pressure and heat to clean the surface. Soft washing sprays the cleaning solution and the rinsing water at about 60 psi significantly reducing the chance of damaging the exterior, penetrating the structure, or leaving permanent marks on other surfaces. For reference, pressure washing is typically putting out 4000pst. The soft washing process not only cleans the surface it also sanitizes it. Once the detergent has done its work, we rinse off the area using a spray gun that releases 8 gallons of water per minute.
With the soft washing process, the detergent does the work instead of the pressure. The detergent kills mould, mildew and algae. It can then be rinsed off with clean water at low pressure. For tougher areas like aluminum gutters or metal window trim, a bristle brush is used for agitating.
Yes usually. It all depends on what material you are cleaning. There are surfaces and certain conditions wherein high pressure is necessary, but the professionals at Alblaster know just what the right situation is for that. Some advantages to soft washing are that it requires less pressure than a pressure washing, the final result is that the surface isn’t just washed, it is disinfected, the detergent does a better cleaning job, the clean lasts longer, there is far less chance that the water will damage the surface or structure of your building. This process dramatically reduces the chance that the water will damage the surface you’re cleaning.
That depends on your location and what your surface is made of, but typically washing your surface every 2 to 3 years is a good idea. If more time goes by, the mould, mildew and algae can build up and cause possibly cause permanent damage and cause costly repairs. You’ll notice the difference, once we’re on the job.
The two main detergents we use are Sodium Hypochlorite (bleach), along with a surfactant or foaming agent. There are different types of surfactants for different surfaces. Alblaster makes sure that all of our detergents and chemicals are 100% non-toxic and biodegradable.
Yes. But avoid soft washing roofs in the rain. They should not be soaking wet when the detergent is applied, and it is a much safer job on a dry day.
Yes, just use responsibly. It is safest to make sure everyone other than the operator avoids the area during the cleaning process. Plants are not a problem, as long as you wet-them-down before and after applying the detergent. Ultimately, the Bleach is biodegradable. It would be best if you keep your pets inside during the cleaning.
– Close and secure all windows and doors
– Unlock gates or any entrances that might prevent access to your property
– Make sure all garden hose tapes have a water flow.
– Report any faucet leaks or concerns at the time of estimations
– Please place a towel behind the bottom of the doors.
Yes with the right amount of degreasing, you can easily remove these stains.
– PSI stands for “Pounds Per Square Inch”. When talking about pressure washers it’s the strength coming out of the nozzle. Your typical garden hose has about 40 PSI.
– A lighter-duty electrical pressure washer has anywhere from 1000 to 1200 PSI. A heavy-duty gas modal pressure washer operates at the 3000 to 5000 PSI range.
Not necessarily. The correct washing technique is to use light pressure (PSI), with the right cleaning agents and a large amount of water.
Typically most people tend to pressure wash their properties in the spring/summer. Makes sense, it’s the nicest time to enjoy it. However, there are some situations you may want to reconsider. If by any chance you have a business or home facing north you will notice moss tends to grow and stain even faster. In these situations, the more frequent the cleaning, the less pressure needed, which is better for the material.
Usually, we can give you an estimate within a day or two.
These lines are called wound marks. Typically you’re not supposed to use wands to clean driveways for this reason. You should always use a flat surface cleaner.
Flat surface cleaners provide a more even and streak-free clean. Surface cleaners are a very important pieces of equipment that Alblaster Pressure Washing has in every truck.
