If they are not too bad here's what you do:
Mix about 1:6 white vinegar and water (one part white vinegar to 6 parts water) in a spray bottle. Add a small amount of joy or dish washing liquid to the mix. Spray the class, let sit for a few minutes. It should come clean.
If it needs more work, you may use a 000 steel wool. It will not scratch the glass and aid in the removal process.
You can use 20 Mule Team Borax. It is still available today. Some people should wear gloves when using this product.
Fill your coffee pot with white vinegar and leave it until morning. Than, use magic eraser, wash it with soapy water (ordinary dish detergent) and rinse it with warm water.
If you have hard water you should get a water filter. You can get a brita water pitcher for around 20 to 30$ and then use that water for coffee.
No, hard water is in the water, it is not caused by the type of pipe.
Hard water could combine with your creamer and cause tiny ceam floaters in your coffee. If your a coffee purest, try distilled water for a constant creamy cup.
Boil some water in a pot and dump the stuff in there. Have some friends over to share it with you. Or buy a new thing of it.
Kaboom! Kaboom!
Try the Magic Eraser. That usually gets rid of a lot of hard to remove marks.
The issue is that the product has dried on the window. This creates a nasty streaky look that is hard to remove. There are two options to remove this problem. Fist the natural way you can try Apple Cider vinegar on the marks. If this does not work there is a product at Auto Parts stores call Dura-Gloss Water Spot Remover. This product will take the streaks right off
Reverse osmosis water filter do indeed remove hard water minerals - up to 95% of calcium and magnesium ions. These are the ones that cause hard water problems.
If this particular model has a reservoir for the water, you simply fill the reservoir half and half with white vinegar and water and brew it through an empty filter. After that runs through, run a full reservoir of fresh water through unless you enjoy pickle-flavored coffee. Do this quarterly if you have extremely hard water. If you use distilled water, you'll never need to de-scale the coffee maker and your coffee won't be tainted by off-flavors from the tap water. If your coffee maker does not have a reservoir, but is plumbed into a supply line, you'll need to follow the manufacturer's recommendations--which probably involves breaking the connection and pumping vinegar water through the coffee maker.
Umm... i think it would be... hmmm... i dont really no. Maybe you should just wipe with water? (remember i said Maybe) Water will not remove wax. If these were was crayaons. The front of the LCD is a thin layer of glass so many solvents that will remove wax (and other marks) will not affect the glass but will damage any plastic (around the edges) so be real careful. Do not push hard the glass is very thin. I read (BUT HAVE NOT TRIED) the following: Use spray insect repellent and a rag to remove the wax / crayon marks. then common window spray to clean the glass.
The glass could have traces of magnesium in it which when combined with hard water would create magnesium-oxide. This chemical change would turn the water black.
Often, just a dry brushing will do the trick. Use a very clean toothbrush, and just buff the stains and the area around it. If that doesn't do the trick, you may need to run it up to a dry cleaner.
