How to Do Laundry with Hard Water

How to Do Laundry with Hard Water. Hard water is rough on your clothes because the calcium and mineral deposits in the water stay in the fabric, causing them to wear faster and fade. These minerals also trap dirt and soap in the clothing, leaving them looking yellow and dull. Proper laundering helps your clothes last longer and leaves them looking newer longer.

Step 1

Choose detergent-based products for your laundry rather than soap-based products. Detergent-based products work better in hard water, whereas soap-based products don't clean as well. Choose a heavy duty liquid detergent or low-sudsing phosphate detergent.

Step 2

Read the label on your detergent to see how it performs best in hard water. Follow the recommendations on how much to use.

Step 3

Reduce the temperature of your boiler to 55 degrees Celsius to reduce the amount of mineral build-up in your pipes and tanks. The lower the mineral deposits in your pipes, the more efficient your washer will run.

Step 4

Add a water softener to your laundry such as Calgon Water Softener. Calgon removes hard water minerals in the fabric of your clothes that hard water can cause, which leaves your clothes looking brighter and cleaner, while at the same time helping them to last longer. You can buy this product in liquid or powder form.
