Las Vegas is unlike any other location around the country. In just a few hours after a wash, my personal truck was covered in fine silica sand that surrounds the Las Vegas valley. Las Vegas is surrounded by hundreds of dry lake beds and with just the slightest of winds the dirt and dust in carried up into the air and blown all over the valley.
If your cleaning company prefers to dry wash or believes their chemicals can safely clean your plane get a second opinion. This fine silica sand is like tiny bits of sand paper that would be rubbed all over your aircraft creating fine scratches and swirls damaging the gloss and protection of your paint.
At Crowe Aviation we utilize foam guns rather than a bucket and brush method. This way the foam lifts and removes the dirt and grime rather than redepositing the dirt back onto the aircraft with the bucket system.
When choosing a cleaning company always remember you get what you pay for, and cheaper is not always better. A cheap wash now could cost you TENS OF THOUSANDS in paint correction in the future. Most importantly do your research, there are always many cleaning companies willing to get you in the door. Then after a few months quality goes down and pricing goes up. We price right the first time and maintain quality throughout the business relationship.
