Tip: Use Scrubbing Bubbles for Hard Water Spots

By FRANZ 1

My husband read so many solutions on removing hard water spots on windows, but nothing ever worked for him. The windshield on our motor home was so stained from the water that would run down it, that we tried everything on the market just like so many others. We bought so many products from acid wash, scrub with SOS, to Comet.

I always use Scrubbing Bubbles for everything in my house. I told my husband for so long to try Scrubbing Bubbles but he always told me, "No that isn't going to work", until one day when he was frantic, he did try Scrubbing Bubbles along with extra fine steel wool. He couldn't believe his eyes. The glass is crystal clear and just like new. Now he won't use anything else just like I won't use any other product except for Scrubbing Bubbles inside.

So every one who is at their worst with hard water spots please use this product. It really does work. I know this sounds like a infomercial, just try for yourself.

Scrubbing Bubbles Fan!

Question: Cleaning Hard Water Spots on Windows

I have four 10'X6' windows (all glass) and about 15 smaller windows of different sizes that get sprayed by water containing calcium, and various other minerals that will not wash off with soap or other washer solutions. I presently use dish soap and hot water and a bit of CLR added. I have used an ammonia solution, vinegar, and rubbing alcohol. Nothing really phases the stains even though the windows get clean, they still show those hard water stains.

We use ditch water to irrigate the lawn by a sprinkler system. Help! I also used automotive products and the products that you are supposed to put on and hose off. They definitely made no difference other than to clean.

I am not sure using CLR would be good for the environment, but as long as you keep it off the ground and wear gloves so you are protected... I can also suggest a razor blade to remove any remaining film/crust from hard water stains. Also found this: http://www.ehow.com/how_5412240_remove-hard-water-stains-windows.html

Tip: Rubbing Alcohol for Cleaning Hard Water Spots

By Karen B. 1 1

I was having trouble getting water spots off my windows until my neighbor suggested using alcohol. I used 91% rubbing alcohol from the drugstore that I already had in the house and paper towels. I didn't even have to scrub. The spots came off like magic.

    If you have hard water spots on your windows they will be hard to clean. Lime away does work but I don't like the harsh chemical. Spray your window with a window cleaner and use a scraper with a blade (the kind you use to remove paint on a window) to scrape over the hard water spots. Be careful to keep the blade flat and not scratch the window. Wipe the window and spray any spots you missed and scrape these away. If you have a huge build up, ammonia water works better than window cleaner but then again, you are dealing with harsh smelly chemical.

    What you are describing as water spots sounds more like Sticker spots. Sticker is a chemical that somewhat water proofs another chemical like fungicides. The make-up of this stuff is pretty simple it's like Elmers glue and dish soap, something I have used when landscaping in large complexes.

    To remove Sticker spots use alcohol, rubbing will work as will alcohol based hand sanitizers. You may also have to use a light abrasive like baking soda. Dampen a cloth with the alcohol or rub the sanitizer on the window and scrub ( you may want to let the sanitizer sit to work it's way into the stains) then polish with the baking soda and rinse. It may take more than one application to remove all this stuff.

    After you get the windows clean seal the glass with a rainex type product. Also check into having the golf course clean up their mess, if this has gotten onto your windows via a pesticide application they could be liable for the damage.

    I do not think there is any health concern as a Sticker product in not used with toxic chemicals.

    Tip: Hard Water Spots on Windows

    By Mary 1

    I have had very hard water spots on my windows from the irrigation system for a year. I just tried Colgate Toothpaste as suggested by Chris on ThriftyFun. My windows are now perfectly clear and it was so easy! I put a little Colgate Toothpaste on a damp paper towel, rubbed it on the glass in circular motions, then I rinsed with vinegar water (anything that would clean the paste off should work). and dried thoroughly. The glass is sparkling!

      Use the vinegar. I'd use a scrubby sponge though. Then after you get it clean, use a lemon oil furniture polish with a terry wash cloth to apply to the glass where the water hits it. You'll most likely have to re-apply every couple of weeks but it sure helps on our glass shower doors.

        Tip: Removing Hard Water Spots From Glass

        By jsruff08 1

        To remove hard water spots from glass, you'll need:

        1. glass cooktop cleaner
        2. non scratch scrubbing sponge
        3. wet rag
        4. microfiber towel

        First off let me say that nothing else worked. I tried everything from glass cleaner with vinegar to straight vinegar. I even tried Scrubbing Bubbles (as found here on this site), but nothing worked. Then the light bulb! I grabbed the above listed items and tried one window - beautiful.

        How to: pretty straight forward - pour cooktop cleaner onto non scratch scrubbing sponge (I used Weiman cooktop cleaner and a Weiman scrubbing pad - red). Work in a circular motion covering the window. Use the wet rag to wipe clean the edges of the window frame. Buff the window with the microfiber towel. Presto!

            Are they water spots caused by hard water, such as that from a sprinkler, hitting your window? If so, vinegar should remove them. Do not dilute when you use it. I would put it in sprayer, and spray on full strength.

              I've tried the vinegar and that does not work. I don't think the owner before ever washed the car. So I'm worried I will not find anything to work on something this severe.

              Tip: Cleaning Water Spots Off Windows With Household Products

              By doggismycopilot 1

              My car windows were covered in hard water spots after mistakenly parking near a sprinkler at work on a hot summer day. I have washed my car three times and paid close attention to the windows, but had no luck getting the spots off. Today I decided to see what I could do with household products.

              Here's what I used:

              1. Crest toothpaste (the non-whitening kind, just simple paste) and paper towels for "buffing".

              2. A mixture of white vinegar (3 parts), distilled water (1 part), and a bit of Dawn dish soap, in a small bottle and shaken slightly to mix.

              3. microfiber car towel

              Here's what I did:

              Step 1: Use a small amount of toothpaste, rubbed onto the worst of the water spots, and buff with a dry paper towel. Pay close attention to the areas where the spots are the worst. If necessary, dampen the paper towel a little once the tooth paste gets too dry. I didn't get the paper towel TOO wet because I didn't want to drip tooth paste onto the body of the car. Not sure what that would do to the paint job.

              Step 2: Dampen the microfiber towel with the mixture of vinegar/water/dish soap, and use it to clean the window overall. Use a little extra elbow grease where you can still see the spots.

              Step 3: Once you have gotten the toothpaste up, flip the towel over and wipe until the streaks are gone.

              After following these three steps, my windows are spot-free and shiny! Now, I'm going to go back and put on some Rain-X on my windows to prevent this from happening again.

                Tip: Use Razor Blade for Water Spots on Windows

                By Cathy Mantello 1

                I water my lawn with very hard water in a very windy area. There is almost no way to keep the water off my windows every time I water. In the past, I had used ammonia to wash the windows and vinegar to get rid of the hard water stains.

                Then last year I broke my arm and missed a whole year of washing windows. This spring the hard water stains seemed to have become part of the glass. Then I thought about the way I clean my cooktop.

                I first washed the windows with ammonia/water solution, then wiped vinegar on a section of the window. I then scraped the glass in that section with a single-edged razor blade. The stains were removed with very little effort.

                  Whink

                  I work on a private yacht, therefore spots are a common thing with all the salt water/negligent crew previous to me. Obviously the darn thing has to look perfect so here's my secret:

                  Use Whink. I put some on a rag and rub it in a circular motion on a 12" by 12" square. I rinse and soap once a square is done and keep going. It's important to rub it good so it looks even because at first whink will sort of stain the window, so rub in well until it looks even (elbow grease needed here). Once the whole window is done, soap it again, dry and put two coats of rain x on it.

                  1) Clean the window with regular window cleaner to get regular surface dirt off.
                  2) Apply the SB Cook Top Cleaner using the provided handle. You'll have to apply some elbow grease, but not nearly as much as the steel wool technique requires. It has a flat pad, so it works great on house windows but I believe it will work on curved car windshields as well.
                  3) The SB pads leaves an oily film behind, so you'll need to clean your windows a second time to remove that film.

                  Archive: Removing Water Marks on Windows

                  I have water marks on my windows and can't seem to get rid of them. There is also a substance that I think is paint, but I am not sure. I have tried vinegar window cleaners, but with no results. I would appreciate all ideas. I just moved into this house and am a fanatic about clean windows .

                  Newspaper and Alcohol

                  I have used newspaper and a sprayer full of alcohol or alcohol and water with excellent results to get smoke haze off the inside of car windows and smoke haze is hard to remove! It should work on the windows, or try vinegar and water instead. As for the paint, get a widget; hold the blade at about a 45 degree angle to the glass and push it toward the paint dots, should scrape them right off. Just be careful!

                  Doobie Pad

                  I had something that sounds similar on my windows and had to resort to a Doobie pad. It's a nylon scrubber with a sponge inside. I used various window cleaners and just scrubbed until all the spots were off then cleaned as usual with clean cloths. I don't like using newspapers, but many people swear by it.
