Hmmm since I have some time I'll point out some simple facts that I find wrong:
"detergent, low water volume commonly found in hose nozzles at home, buckets of water, sponges and towels used in the average home car washing"
- We use high lubricity, sudsing, and in some cases gloss enhancing soaps to clean that paint.
- Bucket WITH devices built to remove grit, but with different rinsing and soap solutions,
- Sponge? Yes if you say Sea Sponge that absorbs with the large cell structure, otherwise it's synthetic chenille or sheepskin mitts that are cared for like fruit!
- Towels? Nope, more like Waffle Weave microfibers that actually absorb!
"average backyard hose is not able to supply enough water along with the detergent action to avoid damaging the car's finish. The most harmful method of washing cars was found to be the special "car wash" brushes that hook on to a garden hose and are purchased from local hardware stores or automotive supply dealers. The use of this type of brush with the low water pressure that comes out of the garden hose is the most destructive on the finish of an automobile"
- Low pressure doesn't necessarily mean more danger, as long as you have the right car soap to loosen dirt and rinse it well. If you have too much wouldn't that involve danger to the car paint?
- Who uses those garden hose brushes?
I could list so many errors in that entire article. It is biased, vague, and extremely verbose. Why don't they show pictures? Results of their work? I'd like to see one car go through 10 washes by an autopian, then another go through 10 washes by a "professional" car wash.
