The back of my house is all windows. They really shine up glass and mirrors, chrome. Window, counters, stainless steel and there are no streaks ever.

I'm not much of a review writer but this product deserves high marks. Although i was skeptical when i ordered them, they work exactly as advertised.

Used “professional” glass cleaners, etc. We live in the southwest where it’s pretty dusty. Idk about cleaning out longevity yet. Much better than glass cleaner and paper towels.

Any rag will do the job, the magic is the polishing cloth. Put a little dish soap and a lot of water on the microfiber cloth, wring it out, wiped the glass and wiped the water off with the blue cloth and the glass looks great.

Very disappointed with these microfiber cloths. When the natural light hits my mirror they are all over it. Do not recommend.
