ProClean Hard Water Spot Remover Kit for Water Spots on Glass, Metal & More - Includes Applicator Pad - Water Stain Remover for Glass, Shower Door Cleaner & Car Window

I needed to get the spots off my bathroom shower door. I tried everything. This was like a miracle. Came sparkling clean.I also used it on my car windows which had acid rain spots. i cleaned them and it also worked well. One product I have to say that after the reviews i read it was true that it was a good product.

This product works wonder! It effortlessly removes hard water stains, soap scum, leaving my glass doors crystal clear. The application is easy and it doesn’t require excessive scrubbing. If you are tired of cloudy, streaky glass, this is the perfect solution! Highly recommended

I just applied this to my shower doors. OMG! I have tried so many different products and this one within minutes the spots were removed. I can't wait to do all the rest of my shower doors. I would recommend this product 10 times over definitely buy it!

Very good stuff. Does what it advertises. Few things that prevented it from being a 5 but rest assure if you need to remove hard water spots on your windows, then this is it.- The sponge it comes with is USELESS and it smells bad. Do not use it! It will scratch your windows. I used a microfiber cloth, and worked it on the window. Spray with water mist. Then buff and dry.- It takes A LOT of elbow grease for hard water spots, which I had. Oh man expect maybe 30 minutes per window. You’ll get a workout.- You really need a polisher machine. You can do with your elbow but it’s a workout. Make it easy, buy a polisher machine.

SUPER SUPER SUPER Product. I’ve been trying to remove water streaks & spots from my glass shower stalls to no avail. I typically dry the glass walls after each use but I had foot surgery. It was hard enough showering on one foot for a whole month let alone drying the glass walls & so I figured it could wait. Well needless to say, after a month the water streaks & spots could not be removed. I’ve spent a considerable amount of money & time on different products on the market through google search & desperate enough to ask for advise on the community facebook page. Lots of advice & tips & nothing would remove them. I even consulted the glass manufacturer where we purchased the shower stall from 6 years ago. they basically said that the glass likely etched due to well hard water & not sure any product could remove the etching. I refused to give up & continued to look for other products. I came across this while looking on amazon for a totally unrelated item. I hesitated for a month before ordering. It was a bit pricey for an 8oz bottle & didn’t really have any faith it would work. I received it today & within minutes I tested a small area as recommended. Took seconds for a square foot area & not much pressure. When the solution faded, i wiped with a damp microfiber cloth & then wiped dry with a dry cloth. I could not believe my eyes. I tried wetting & drying again & again the glass was back to it’s original clarity. I asked my daughter to come by just to make sure it wasn’t just me not seeing the streaks & she assured me that in fact that the square foot area was streak free. I’m SUPER SUPER SUPER happy with this product & wholeheartedly recommend to anyone who has same need. I don’t know what kind of magical wizardry is in this product but you have one happy lady here. THANK YOU GlasWeld. I would give 10 stars if possible.

I haven’t actually used the bottle I just received but have used some from a neighbors bottle. It certainly cleaned up the hard water spots that regular washing wouldn’t do. Since we have hard water every time we washed windows, they looked clean until the sun came up. Easy to use and works. Now if I can show my wife how to use it. LOL.

There was a lot of scrubbing and wiping and more scrubbing 4 and 5 times on repeat and I finally managed to get a small section (3 inches by 20 inches) of my window almost cleaned from the hard water deposits. I would say this product works if you only need a small area cleaned up and if you have a lot of patience to repeat the steps many times. Definitely not a miracle cleaning product. Definitely need more than the one small sponge they send.

This is the best product I’ve ever used for water stain. I will not switch to another product. I have gone through a lot due to my Glass shower doors. We have applied this and have no problems as long as you follow the instructions as stated which are very easy to follow. You will not have problems with water stain, talk about being able to remove water stains. This is a product you must buy for your car windows as well.
