Breathe new life into yellowing cushions:

My initial approach involved using 1 cup of hydrogen peroxide as a bleach replacement.

I also added 1/2 cup of vinegar to the mixture. Vinegar is a powerful natural cleaner that not only removes stains, but also acts as a fabric softener.

Note to readers: The use of hydrogen peroxide and vinegar is mentioned in this article. It is safe to use them in series, but mixing them directly in the same container can lead to the formation of paraacetic acid. It is a corrosive acid that can damage the skin, eyes, nose, throat and lungs.

Then I poured in a quarter cup of lemon juice. Like vinegar, lemon juice has acidic properties that break down stains and leave behind a fresh lemon scent.

Once the pillows are completely submerged in water, let them soak for 30 minutes. Flip it over to make sure it's soaked well on both sides, and let it sit for another 30 minutes.

After the first half hour I wasn't completely satisfied with the progress. Keeping in mind that my washer is quite large, I decided to add another cup of hydrogen peroxide. Everyone's machine sizes are different, so adjust quantities according to your needs. (In all, I used 2 cups hydrogen peroxide, 1/2 cup vinegar, and 1/4 cup lemon juice).

Continue adding your favorite laundry detergent and run the standard wash cycle.

After washing, check your pillows. If they reach the desired level of cleanliness (like mine), you can dry them. If not, you may need to repeat the process or explore another method described below.

I set the dryer on a low setting and it took about 30 minutes for the pillows to dry.

Right out of the dryer, the pillows were a feast for the eyes and I was very happy with the results.

What other methods have you tried? (this is the safe color)

Let's move on to the next batch of pillows, which have also been pre-washed and dried. I soaked it in a mixture of 1 cup laundry detergent, 1 cup baking soda, 1 cup borax, and 1 cup castile soap. After a similar soaking and flipping process as before, I ran the wash cycle.

The change was noticeable, but one pillow remained more yellow than I would have liked.

In conclusion, these methods provide great bleach-free alternatives for anyone who wants to avoid harsh chemicals. Works effectively on pillows, pillowcases, and mattress toppers.
