      Aspirin is often used to treat headaches, fevers, or aches. But it also has many alternative household uses. One such use is in laundry, where it is said to remove stains and brighten white clothes.​

      It not only whitens clothes but also removes unwanted odors. This article explains how to use aspirin in laundry.

      Why Use Aspirin in Laundry?

      Aspirin can be very effective at breaking down stains, as it contains acetylsalicylic acid, an active ingredient that helps remove stains and brighten. It can tackle mold spores that could be present in fabrics.

      It is very helpful to those dealing with yellowed shirts, sweat stains, or mildew smells on towels. In addition, it is cost-effective to use as a laundry hack. It is also eco-friendly, making it a more sustainable choice free of chemicals or artificial whiteners.

      Aspirin also has the least possibility of damaging the fabric. Unlike bleach, which can weaken fibres, aspirin is much gentler on clothes.

      How to Use Aspirin for a Full Wash Load?

      Using aspirin to brighten an entire load of laundry takes a bit of preparation. For this process, you will need two gallons of water and five aspirin tablets. Start by dissolving five aspirin tablets in about two gallons of hot water in a bucket or basin. Once the tablets are fully dissolved, add clothes and allow them all to soak overnight.

      The next day, move the clothes to the washing machine. Add 3 more aspirin tablets to the load, then run a normal wash cycle. For an extra-brightening effect, skip the dryer and hang the clothes outside in direct sunlight.

      This method can be repeated regularly to brighten whites, but it is more time-consuming than simply adding bleach to the load. For people with sensitive skin, it is better to avoid bleach and use aspirin as a gentler alternative.

      How to Use Aspirin for Stains?

      For direct stain treatment, aspirin can be applied directly to the spots on the fabric. To follow this method, grind 3.25 tablets into a fine powder, then add a small amount of water. Next, mix this paste and spread it over the stained areas.

      After letting it sit for a few hours, wash the clothes as usual without any bleach. Once the wash is done, hang the clothes outside to dry.

      This method maximises the use of aspirin by targeting the stains directly. However, the results may vary depending on how tough the marks are.

      How to Use Aspirin Directly in the Washing Machine?​

      Aspirin is also effective for laundry when placed directly in the washing machine. Take about 8 to 15 aspirin tablets and put them at the bottom of the drum. To this, add dirty or stinky laundry and preferred detergent as usual.

      Depending on the fabric and its sensitivity, set the machine to either a warm or a hot wash cycle. For sensitive clothes, it is better to use a warmer cycle. Using aspirin will help reduce odors and give the laundry a much fresher feel.

      How to Use Aspirin to Get Rid of Blood Stains?

      In addition to various types of stains, aspirin is very effective at removing stains, especially from lighter-coloured fabrics. To use this hack, dissolve aspirin tablets in cold water, which will help fade stains like sweat stains, blood stains, etc.

      It is important to ensure that the water is cold, because hot water can set the proteins in the blood deep into the fabric. This will make it hard to remove the stains.

      ​Alternatively, you can soak the clothes in cold water, crush an aspirin, and rub the powder into the stain. After letting it sit for a few hours, wash the clothes as usual. This method will not be effective on its first use, so it is important to repeat the process until the spot vanishes.

      Conclusion

      Laundry is a tedious daily task, especially when it comes to light-coloured clothes and stains. To ease the laundry process, it is important to use several hacks, such as adding aspirin to the laundry. This is cost-effective and is a gentler option when compared to bleach.  While it may take more time and effort, it can be worth trying for those who want to avoid harsh chemicals.
