There are a few methods for removing blue-green stains with everyday household items. White vinegar is an effective cleaning solution, especially when combined with an abrasive material like table salt.
White Vinegar works wonders on hard water stains. I use it for showers, old fish tanks, etc. Spray it on a few times over 30 minutes or so, then use a brush attachment for a drill to make the scrubbing easier.
Baking Soda/Peroxide Method
Be sure to use a soft brush on porous or marble tile so it won't scratch the surface. You can also make a paste of two parts baking soda mixed with one part water. Apply the paste to the stain, let it stay overnight, and then scrub the stain with a soft nylon brush.
Vinegar and Baking Soda: One of the most effective ways to remove hard water stains from tiles is by using a combination of vinegar and baking soda. Mix equal parts of vinegar and water in a spray bottle, then spray the solution onto the affected tiles.
Hydrogen Peroxide Mixture
This mixture works as an effective bleaching agent that can remove dirt and grime from your tiles, while the liquid soap helps dissolve grease. To create this cleaning solution, mix one part hydrogen peroxide, three parts baking soda, and one tablespoon of liquid soap to create a paste.
In most cases, blue/green tinted stains are caused by the water flowing through your pipes having a low (acidic) pH. Chances are your water pipes are made of copper and the blue discoloration is the result of the insides of the pipes being attacked by the aggressive low pH water.
This discoloration is surprisingly difficult to remove–a regular cycle with bleach is usually not enough. Instead, try presoaking with ¼ cup Clorox® Disinfecting Bleach added to 1 gallon of water for 5 minutes, and then machine wash the items again.
Clean the grime off your tub, shower or tiles
You can also combine Dawn with vinegar for stronger cleaning power, especially when tackling hard water stains. Just combine them in a spray bottle, spray down your tub or shower and let it sit for a few minutes, then scrub it down.
Additionally, a paste made from baking soda and water can be effective for natural fabrics like cotton or linen. Apply the paste to the stain, let it sit for a few minutes, and then rinse thoroughly. When used correctly, these techniques can significantly reduce or eliminate blue dye stains from your clothes.
Mix 1/4 cup of white vinegar, 1 tbsp. of dish soap, and water in a spray bottle. Spray the area liberally and let soak for 5-10 minutes and then blot again with a clean, dry towel until stain is removed.
Hydrogen peroxide is a very effective stain remover for protein- and plant-based stains. It works well in treating blood, mildew, fruit and vegetable, and dye-transfer stains.
To remove tough stains from ceramic and porcelain tiles, you can use a mixture of baking soda and water or a paste made of hydrogen peroxide and baking soda. Apply the paste to the stained area, leave it for a few minutes, and then scrub gently with a soft brush. Rinse thoroughly afterwards.
Mix a Poultice: Combine baking soda with water to create a thick paste. Apply on the Stain: Cover the stained area on the marble surface with the paste. Cover and Let Sit: Cover it with plastic wrap and let it sit for 24 hours to draw out the stain.
The primary source of blue or green staining in plumbing fixtures is the corrosion or dissolving of copper pipes and fittings. Such corrosion is predominantly driven by water that exhibits a high degree of acidity. Specifically, when water has a pH level below 7 or a Total Dissolved Solids (TDS) measure below 100 mg/l.
However, you can go blonde after bleaching your blue hair. Does blue hair fade to green? Yes. Blue hair fades to unpleasant hues of green because of the yellow undertones of bleaching that react with blue and turn green.
Soak stained fabric in a mix of one part hydrogen peroxide and two parts water for about 30 minutes before washing. It aids in lifting off the stains, making the washing process a breeze. Apart from these applications, hydrogen peroxide is also an effective deodorizer.
Just mix vinegar and baking soda into a paste, apply to the stains and wait about 10 minutes before wiping off. To prevent these stains, you'll want to have your water tested to see what is making your water so corrosive. Depending on your particular problem (low pH levels, level of salt in water, etc.)
Put the shower head in a bucket or plastic container and cover it with white vinegar. Leave it to soak in the vinegar for at least 30 minutes, preferably around an hour. Don't leave brass shower heads in vinegar for longer than 30 minutes. Take the shower head out of the vinegar and rinse it with water.
Try isopropyl alcohol! I stain microscope slides at work and methylene blue is one of the stains we use. When we spill it on the floor or counter we pour alcohol on it, let it sit, wipe with paper towel and repeat.

White vinegar is a natural, non-toxic cleaning solution that is generally safe on most tile surfaces. It is also an affordable and easily accessible alternative to commercial cleaning products, which can be more expensive and potentially harmful to the environment.
