In modern “brushless” car washes, cloth strips called mitters have replaced brushes. Mitters are easier on most cars’ finishes than brushes are. This is especially important with the new clear-coat finishes found on many cars today, which are more easily scratched than older finishes are.

Summary
Modern car washes use mitters rather than brushers. Mitters are easier on most cars’ finishes than brushes are. This is important today, because many cars have clear-coat finishes that are more easily scratched than older finishes.

Strongly Supported Conclusions
If brushes were used on cars today instead of mitters, more cars would have scratched finishes today than is currently the case.

A
When car washes all used brushes rather than mitters, there were more cars on the road with scratched finishes than there are today.
Unsupported. This doesn’t account for potential increases in population and car use. In the past, although there may have been a higher rate of scratches on cars, there may have been fewer cars overall. So, the overall number of scratched cars might have been lower in the past.
B
Modern “brushless” car washes were introduced as a direct response to the use of clear-coat finishes on cars.
Unsupported. We’re not told the reason modern car washes were introduced. The fact modern car washes are better for clear-coat finishes does not imply the clear-coat finishes caused modern washes to come about.
C
Modern “brushless” car washes usually do not produce visible scratches on cars with older finishes.
Strongly supported. Mitters are easier on most cars’ finishes than brushes. This is important because clear-coat finishes are more easily scratched. This suggests that when used on older finishes, mitters aren’t likely to produce scratches, at least not any we can see.
D
Brushes are more effective than mitters and are preferred for cleaning cars with older finishes.
Unsupported. We’re not told whether brushes or mitters are more effective for cleaning. We’re only told which one is easier on cars’ finishes.
E
More cars in use today have clear-coat finishes rather than older finishes.
Unsupported. We know that many cars today have clear-coat finishes. But we don’t know whether most (over half) cars today have such finishes.
