A.J. Funk & Co. Ammonia-Free Original Formula Glass Cleaner, Clear Purple

This is the best glass cleaner you will ever use. No smudging or streaking if you follow directions and wipe it completely dry. Seems to resist water spots and dog slobber on car windows. It used to be available in stores, but as usual the bigger "fish" with the big marketing campaigns wiped out this little guy, in stores anyway. Windex is horrible. I was finally able to find Sparkle again on line. Use this. You will be happy.

This seems to be a smear free product. In other words when I wash windows and mirrors there are no streaks. Like it so far. Kind of expensive, but seems to do the job I was looking for.

We bought a small bottle of this stuff at a home show and loved how well it cleaned our eyeglasses. Was happy to find a huge bottle on Amazon and have since started using it on mirrors and windows instead of Windex - no streaks.

Windows look great when it is used. So does the front of the microwave and anything else I use it on.

Have been using Sparkle for several years. It doesn't contain alcohol or ammonia, so it's safe to use on tinted windows, whether in the home or on your car

This product really works! Just wish it was cheaper to buy

CLEANING TIP: EXCELLENT TO CLEAN GRANITE MEMORIALS.

Good product, we got it from the recommendation of a supplier for monitors we sell and show...does not streak like many glass cleaners-and thus is perfect to use with electronic equipment like monitors
