especially like the after pic!!

before i add a new type of detail tool to my garage the question i always ask is "is it really worth it?"
big blue or paper towels do a great job on my glass- in your opinion, do i "need" this towel?

 

"Need" is such an ugly word. Seriously though, I would say you could 100% get by without using this towel. It's not so special that it's going to clean your glass and then rub your back.

This being said if you feel you're having trouble cleaning your glass to a clear streak free finish then I think this towel could help you out. As described by the manufacturer most WW towels are woven in such a way to emphasize absorbency. This towel however is woven to enhance cleaning ability. It's still very absorbent though which I feel is a result of the waffle weave shape.

 

after thinking about this, its not the outside of the glass that i need help with, but can always use help on the inside!
sounds like a reason to need this one!!

 

9 out of 10 details I don't even clean the exterior glass with glass cleaner. I just wash it with the rest of the car and then dry it. This is typically enough to give me a nice clear piece of glass. Usually I can get by with this unless it's a hot day and the water dries quickly on the glass leaving water spots.
