Pressure washing and power washing are relatively easy to explain. They are basically one in the same, just pronounced differently by different people. They both have the same meaning. As a general term used for cleaning an exterior object with water, the term is used in a broad range. There are many different ways to pressure wash an object, and these different ways are what separate the fly by night companies, and the true professionals. Most surfaces need to be soft washed, rather than pressure washed, and this is why most amateurs damage property on a regular basis. Soft Washing is cleaning an object using less than 1,000 psi.
A fly by night company will have your average pressure washer, bought from a department store that has only one power setting. Unfortunately, that power setting is on high, which will damage most surfaces. A professional pressure washing company like Kingwood Pressure Washing, has the ability to soft wash surfaces to prevent damage from occurring.
Oil Stain Removal
Oil stains can be quite difficult to remove. “Can you remove these oil stains from my concrete?” Yes, and maybe no. Oil stains are plain and simple tough. It depends on many factors if oil can be removed with basic concrete cleaning. The most important factor is how long the oil has been on the concrete. Also, was anything put on the stain already?
Long term oil stains are almost impossible to remove completely, since they have had time to set in the pores and dry. Long term oil stains can be removed enough to were only a shadow of the oil stain is visible in most cases. Another question is what type of oil is it? Some oils are capable of being removed easier than others. And finally, how porous is the concrete? With all these factors going into the removal of an oil stain, it is hard to be able to tell someone that concrete cleaning can remove the oil stain completely. We always recommend performing a full driveway cleaning when removing an oil stain, instead of just cleaning the oil stain alone.
