Q4 EVER Auto Care Glass Polish Hard Water Spot Remover (100 Grams Cream)

Worked really well, used it mildly over a stubborn hard water stain on my windshield, cleaned it up in seconds. Recommended

Good product and working as described but for a small scale need to spend more time

Worst product!I used this product in my new car glass and got many scratches even though I used best microfibre cloth. Don't buy this product as it will spoil car glasses

Bought this to clear hard spot on my Car windshield and end up getting scratches and blurred the vision on night and rainy days. I was about to throw this away but before that used this to clean my bulelt Engine cover and voila it clean as new. Atleast it served anotehr purpose hence the 3 star

Had water spot on entire glass of my car. This product removed it fully. I used it directly on the glass and used hands to rub, then used a cloth to wipe it off. Very good product.

Excellent product

My car windows have many water spots. The washing boy used to splash hard water from borewell and allowed it to dry on glass resulting in these spots. This product does work. But the liquid is thick, does not flow easily, dries out on the micro fiber cloth quickly. And you have to really work hard for a long time to clear a tiny area. But it does clear the water spots. Not sure whether one can use electric tools (angle grinders with felt pads) for faster results. Also have not tried felt pads instead of micro fiber cloths for larger contact area. Don't use scotch Brite utensil cleaning pads. It clears the water spots with less effort but leaves scratches. Have not used cerium powder too though intend to try later.

Effective Solution for Hard Water SpotsI recently purchased this hard water removal solution, and I'm impressed with the results. The solution has a thick, creamy consistency that makes it easy to apply.I found that applying the solution twice or thrice was necessary to completely remove hard water spots, but the effort was worth it. After using this product, my glass surfaces are noticeably shiny and free from hard water spots.I particularly appreciated how well it worked on my car windshield, leaving it looking neat and clean.Overall, I'm satisfied with this product and would recommend it to others dealing with hard water spots.
