This product does work. You have to work at it, but it does work. It’s not an easy task when my windows were pretty streaked with hard water stains.

Excellent product,will purchase again thanks

Not only does it work exceptionally well on my vehicle but I tried it on the glass of my stand up shower and it looked like brand new in 30 seconds. I’ve tried everything possible on that glass and nothing touched it til now

I’ve tried many products, with a little sweat, this product is this best so far. This product is great

This stuff is my go to for any glass cleaning with hard water spots. It’s worked amazing on our shower doors. My husband asked me to try it on his C10 windows. Look at them shine!!!

We purchased this to take care of hard water spots on the side mirrors. The spots were removed easily. Now onto the sliding glass doors.

Not gonna lie I have really caked on water spots and they took a but of time but eventually they came off, the fact they put a bible verse on the side of a bottle too is a nice touch

works great!!

I have tried a bunch of cleaners that were suppose to remove mineral water spots for the windows of my truck. Even oven cleaner.

This product appeared in a ad on my Facebook page. Researched it. Read the reviews. Well ****. Decided to try it.

Well worth every penny! Just don’t use on a hot sunny window. Dries to fast.

I recommended Sud factory to the dealer where I purchased my truck when having it serviced.

Lived up to the hype. Did a fantastic job on my windows with water spots.

I purchased this in hopes of getting years of water spots off of my windows and windshield of my vehicle. I have tried other products without good results. Upon using sud factory for glass, this product works FANTASTIC!!!

I love this stuff. Super easy to use – I do a couple of coats every 4 – 6 months after giving the car a good wash and dry.. So much quicker and easier than wax, and seems to hold up well. Definitely sheds water, dust practically rinses off with a quick spray of the hose.

This is the best stuff I have ever used to remove any hard water with ease. This is my go to with an abrasive pad nothing can stand a chance

This stuff really does what it says it will

Worked on shower doors, and on the vehicles! Thanks SUD Factory!
