If your home is dealing with hard water problems that have probably stayed for years, cleaning it without the proper hard water solution will become ineffective and cannot give you the best results, because a normal detergent soap cannot clean the chalky white mineral deposits built up on shower heads, drains, and soap scum that stick around your tiles, your laundry that always feels dull, and your dish plates that have white spots on them.

If your home has high concentrations of calcium and magnesium, detergent alone or even mixed with hot water cannot clean it. But there are homemade effective cleaning tools that you can make in bulk and keep aside to use for your everyday cleaning.

Homemade cleaning solutions for removing hard water on tiles, shower faucets and glass doors

Hard water makes your home look dirty — even though you clean it, your glass doors and walls still show that chunk of white spots all over. The best homemade solution for the hard water effect you mix for cleaning your shower head, glass doors and tiles — for stone tiles you need a completely different product mix, which I will explain later on.

Mixing white vinegar and highly liquid soap are the two effective products you need, because the acid in vinegar breaks down the mineral and calcium deposits, then pairing with a liquid soap makes it thicker, cutting through the grease that clings to the surface.

• Preparation: Before you mix the two, warm the vinegar without boiling it, so when you pour the thick liquid soap in it, it will blend smoothly into the liquid. Then pour them into a spray bottle and shake until completely combined.

• Application: Spray the solution over your tiles, shower heads, and glass doors. Let it sit for 5 to 10 minutes to give the vinegar time to break down the hard water bonds. Then wipe and rinse thoroughly with water, but if you have heavier buildup that has lasted longer, leave it for 30 minutes, then scrub with a soft sponge and rinse. After showering, always clean the shower faucet with it.

How to remove hard water stains on stone tiles

Stone tiles need a different mixture to remove hard water stains, because vinegar cannot be used since it is highly acidic — as the Natural Stone Institute Care & Cleaning Guide states, vinegar or lemon juice, or other cleaners containing acids, should not be used on marble, limestone, travertine, or onyx surfaces. No matter how much liquid soap you mix with the vinegar, it will make the stone dull and discolored.

The most effective homemade cleaning solution for stone tiles that you can use every day is distilled water, which will prevent adding more minerals to your tiles, mixed with 70% isopropyl rubbing alcohol and a milled dish soap. Pour all the ingredients into a spray bottle and shake to mix. The smell could be strong, so you can add an essential oil for a clearer scent.

Homemade solution for hard water laundry stains

Hard water makes your clothes, sheets and towels feel dull and rough. Even if you use a lot of detergent, it won't give you the clean result your clothes need, because soaps don't work well with hard water — they turn into soap suds. To keep your laundry fresh and strong, and to remove the hard water stiff stains on your clothes that don't wash away, you will need to buy soap paired with a water softener, or make your own homemade detergent that has a water softener in it.

Borax can work as your water softener when making the soap, because it helps erase residue and enhances stain removal, paired with washing soda and grated Castile soap. Mix them thoroughly in a large bowl, then transfer to a glass jar or airtight container, and keep away from humidity. When washing, apply two tablespoons directly to the washing machine drum per load. If you are washing whites, add a splash of vinegar to the fabric softener to break down mineral stiffness during the rinse cycle.

Homemade solution for hard water stains on plates and dishwashers

Hard water leaves white spots and a chalky look on glasses and ceramic plates, making the plates look cloudy or dirty when they're actually clean. To prevent hard water spots from forming during the drying cycle, your solution is mixing washing soda — which helps dissolve grease and target water hardness — with borax, kosher salt and citric acid powder.

• Preparation: Mix the washing soda, borax, and salt first, then add the citric acid powder last so it doesn’t react with moisture in the air and cause the powder to clump up. Store it in a tightly sealed jar in a dry place.

• Application: If you are using your hands to wash the plates, add a splash of plain white vinegar directly to your final rinsing basin so plates can dry completely spot-free. If you are using a dishwasher, add 1 and a half tablespoons directly into your dishwasher detergent compartment per cycle.
