How Does Hard Water Affect Detergent?

What exactly is hard water though? The area you live in affects the quality of your water.

Your water is “hard” if it has a high mineral content, including calcium and magnesium (2). The water has collected these mineral particles from rock and soil that it passes through. Soft water, the opposite, is water that contains less of these minerals.

Unfortunately, hard water can affect your laundry and make it harder to deal with. What hard water can do to laundry and detergent:

  • It makes it hard to mix the detergent: Hard water isn’t great for laundry because it stops the water from mixing with your detergent (3).
  • It leaves behind soap residue: If the detergent doesn’t mix well, you’re left with a soapy residue on your clothes. Not pretty. If you’ve ever noticed chalky, streaky stains on your clothes, you could have hard water!
  • Your clothes will be stiff: Hard water can leave clothes stiff and rigid. We’ve all had that one towel that is scratchy and icky after a spin in the washing machine. This is unsightly and very uncomfortable to wear.
  • It doesn’t clean your clothes properly: As opposed to soft water, hard water doesn’t end up cleaning your clothes properly since the detergent doesn’t mix well. That’s not what we want at all.

Choosing the Best Laundry Detergents for Hard Water

Which is best for hard water? Powder, liquid, or even homemade detergents?

Regular powder detergent doesn’t mix well with hard water. Therefore, you might find yourself using hotter water and more laundry detergent to clean your clothes properly. This is a waste of energy. Plus, it’s not as kind to the environment.

However, we can recommend some good powder detergents specially formulated for hard water.

Liquid detergent, on the other hand, is generally easier to use with hard water. Liquid laundry detergents are better at mixing with hard water. This is because of the nonionic surfactants which can resist water hardness better (4).

Perhaps you want to go down the route of making your own laundry detergent. Unfortunately, this might not always be the best option. Soap doesn’t do well with hard water. If you do still make your own laundry detergent, you can increase the amount of Borax by at least one third for better results.

Take Note

If making your own laundry detergent, test it each time to make sure it’s performing well. Clean clothes are the goal here!

How to Do Laundry With Hard Water

If you’ve discovered you’re unlucky enough to live in a hard water area, how in the world are you supposed to do laundry? Fear not, because there are many ways to battle this issue with as little effort as possible.

  • Use the right amount of detergent: Once you’ve found the best laundry detergent for hard water, read the instructions carefully. Too much or too little detergent could end up being pointless for cleaning your clothes.
  • Get a water softener: You can easily add a water softener to your clothes. This will help remove the minerals that your hard water brings.
  • Keep your washing machine clean: To prevent mineral build-up, regularly clean your washing machine. Every washing machine has different cleaning instructions, so follow yours carefully.
  • Don’t do extra rinses: It’s tempting to rinse your clothes again if they feel stiff or unclean. But all that does is put more hard water minerals into the clothes, sending you back to square one!
  • Wash clothes in warm water: Not too hot, and not too cold. Wash your clothes at 90 degrees Fahrenheit. This will help keep the hard water minerals at bay.
  • Use good detergent: Make sure you use a good detergent for hard water. This will be the key to getting clean and soft laundry.

Removing Hard Water Stains

It’s time to start fresh with your hard water laundry techniques. But what if you have hard water stains on your clothes right now? We can give you some helpful tips to remove hard water stains so that your clothes look brand new again.

  • Baking soda and vinegar: You can make a paste using vinegar and baking soda. Rub the paste over the stain and let it sit for 15 minutes. Scrub clean and rinse with cold water. Wipe dry and wash as normal.
  • Lemon juice: Lemon juice is a natural and powerful tool for removing stains. Spray lemon juice onto the stain and leave for 10 minutes. Rinse, and check if the stain has gone.
  • Distilled white vinegar: If you don’t already have this product in your laundry room, it’s time to start. You can put one cup of vinegar into the detergent compartment of your washing machine and run the machine on the rinse cycle. Make sure to wash at a low temperature. Repeat until the stain has gone. Air dry when done.

You can rely on these tips to help you remove hard water stains.

Don’t Let Hard Water Win

It’s definitely annoying to live in a hard water area. Tap water tastes different, your bathtub needs vigorous cleaning, and your clothes might feel stiff and unclean. But there’s no need to fear now that you know the best laundry detergents to use.

Make sure to use the correct amount of detergent as recommended on the bottle for the best results. Keep your washing machine clean, use cool or warm water, and if all else fails, get a water softener to aid your detergent.
