It is tough to prevent white linen from yellowing, (and I am definitely one of the majority who is easy to get clothes dirty) So here I offer the tips to whiten a white linen blazer, and you should note that always be careful and wear gloves when you practice.
10 Ways To Whiten Linen Blazer At Home

1. Vinegar
To use vinegar to whiten a white linen blazer:
Firstly, fill a sink or basin with warm water and add about 1/2 cup of white vinegar.
Place the blazer in the water and let it soak for about 30 minutes.
After soaking, gently agitate the blazer in the water to help loosen any dirt or stains.
Rinse the blazer thoroughly under cool running water.
If the linen blazer is still not as white as you’d like, you can repeat the process, or you can try gently scrubbing any remaining stains with a mixture of equal parts vinegar and water.
Once the blazer is clean, hang it to dry or lay it flat on a clean, dry towel. Avoid wringing or twisting the blazer, as this can cause the linen to become misshapen.
Once the blazer is dry, you can press it with a warm iron to give it a crisp, fresh appearance.
Keep in mind that vinegar can be a strong and potentially damaging cleaning agent, so it’s important to use it carefully and in moderation. If you’re concerned about damaging the blazer or if you’re not sure whether it’s safe to use vinegar on the fabric, it’s always a good idea to test a small, inconspicuous spot before proceeding with the entire garment.
2.Baking Soda
To whiten a white linen blazer using baking soda, you can follow these steps:
Fill a large basin or tub with warm water and add 1 cup of baking soda. Mix the water and baking soda until the baking soda is fully dissolved.
Place the white linen blazer in the water and use your hands to gently agitate the fabric to ensure that the baking soda solution is evenly distributed.
Let the blazer soak in the solution for at least one hour. For tougher stains, you can soak the blazer for up to 8 hours.
After the blazer has finished soaking, gently wring out the excess water and rinse the blazer under cold running water.
To remove any remaining baking soda residue, soak the blazer in a solution of 1 quart of warm water and 1 tablespoon of white vinegar for 5 minutes. Rinse the blazer again under cold running water.
Hang the blazer to air dry, or if it is particularly wrinkled, you can iron it on the lowest heat setting.
3.Oxygen Bleach
To whiten a white linen blazer using oxygen bleach, just follow these steps:
Fill a sink or basin with lukewarm water and add a scoop of oxygen bleach according to the package instructions.
Place the blazer in the water and gently agitate it to help the oxygen bleach dissolve and penetrate the fabric.
Let the blazer soak for at least 30 minutes or up to several hours, depending on the level of discoloration and the manufacturer’s recommendations.
Rinse the blazer thoroughly with cool water to remove any remaining oxygen bleach and dirt.
If the blazer is heavily soiled or has stubborn stains, you may need to repeat the soaking and rinsing process.
Once the blazer is clean, hang it up to air dry or tumble dry on a low heat setting. Avoid exposing the blazer to direct sunlight or heat, as this can cause yellowing or fading.
Note: Oxygen bleach is a gentle, non-toxic alternative to chlorine bleach, but it may not be suitable for all fabrics.
4.Sunshine
Hang the blazer outside on a clothesline or hanger in direct sunlight for a few hours. The sun’s UV rays can help to naturally bleach and whiten the fabric.
5.Lemon Juice
To whiten a white linen blazer using lemon juice, you will need the following supplies:
Lemon juice
Water
A small bowl or cup
A clean, white cloth
A toothbrush or a small, stiff-bristled brush
Here is a step-by-step guide on how to whiten your white linen blazer using lemon juice:
Mix equal parts lemon juice and water in a small bowl or cup. The amount you need will depend on the size of your blazer and the stains you are trying to remove.
Dip the clean, white cloth into the lemon juice mixture.
Gently rub the stained areas of the blazer with the lemon juice-soaked cloth, using a circular motion.
Allow the lemon juice to sit on the stains for a few minutes.
Use the toothbrush or small brush to scrub the stains, applying a moderate amount of pressure.
Rinse the blazer thoroughly with cold water to remove the lemon juice and any dirt or stains that have been lifted.
6.Hydrogen Peroxide
To whiten with hydrogen peroxide, just follow these steps:
Fill a sink or basin with cold water and add a few tablespoons of hydrogen peroxide. The concentration of hydrogen peroxide should be about 3%.
Place the white linen blazer in the water and let it soak for at least 30 minutes.
After soaking, gently scrub the blazer with a soft-bristled brush or a cloth to help remove any dirt or stains.
Rinse the blazer thoroughly in cold water to remove the hydrogen peroxide.
Hang the blazer to dry in a well-ventilated area. Do not put it in the dryer or expose it to direct sunlight, as heat and sunlight can cause the linen to fade or yellow.
7.Laundry Blueing
To whiten a white linen blazer using laundry bluing, you will need the following supplies:
Laundry bluing
A large bucket or basin
Cold water
A clean, white cloth
Here is a step-by-step guide:
Fill the bucket or basin with cold water.
Add a small amount of laundry bluing to the water, following the instructions on the package. The amount of bluing you need will depend on the size of the bucket and the amount of water you are using.
Stir the water until the bluing is fully dissolved.
Place the white linen blazer in the bucket or basin and soak it in the bluing solution for at least 30 minutes.
Remove the blazer from the solution and gently wring it out. Do not wring it too hard, as this could damage the fabric.
Rinse the blazer thoroughly under cold running water. Make sure to rinse until the water runs clear and there is no trace of bluing left on the fabric.
Lay the blazer flat on a clean, white cloth to dry. Do not hang the blazer to dry, as the weight of the water could cause it to stretch and lose its shape.
Note: Laundry bluing is a chemical solution that is used to whiten and brighten white laundry. It works by reflecting light in a way that makes the fabric appear whiter. However, it is important to use caution when using bluing, as it can cause skin irritation and should not be ingested.
8.Ammonia And Water
It is not recommended to use ammonia to whiten a white linen blazer as it can be damaging to the fabric and may cause discoloration or fading. Instead, you can try the following steps to safely whiten your white linen blazer:
Wash the blazer in cool water with a mild detergent, using the gentle cycle on your washing machine.
Add a cup of white vinegar to the rinse cycle to help brighten and whiten the fabric.
After washing, hang the blazer to dry in a well-ventilated area, away from direct sunlight.
If the blazer is still not as white as you would like, you can try using a non-chlorine bleach, such as oxygen bleach, to gently whiten the fabric. Follow the instructions on the bleach product to ensure that it is used safely and effectively.
Avoid using hot water or heat to dry the blazer, as this can cause shrinkage and damage to the fabric.
Remember to always test a small, inconspicuous area of the blazer before applying any cleaning or whitening products to ensure that they do not cause any discoloration or damage to the fabric.
9.Aspirin
To whiten a white linen blazer using aspirin, you will need the following materials:
Aspirin tablets (2 tablets per quart of water)
Cold water
A clean bucket or sink
A clean, white cloth
Here are the steps to follow:
Crush the aspirin tablets into a fine powder using a mortar and pestle or the back of a spoon.
Fill a clean bucket or sink with cold water.
Add the crushed aspirin to the water and stir to dissolve.
Place the white linen blazer in the water and gently agitate it to ensure that the water and aspirin solution covers the entire garment.
Let the blazer soak in the solution for at least an hour.
Rinse the blazer thoroughly with cold water to remove the aspirin solution.
Hang the blazer to dry in a well-ventilated area out of direct sunlight.
Note: Aspirin can be effective at whitening and brightening fabric, but it may also cause discoloration or fading if left on the fabric for too long.
10.Potassium Permanganate
Potassium permanganate is a strong oxidizing agent that can be used to bleach and whiten fabrics. However, it can also be harmful to fabrics if not used properly. Here’s how you can use potassium permanganate to whiten a white linen blazer:
Fill a large bucket or basin with cool water and add a few drops of potassium permanganate. The amount you use will depend on the size of the bucket and the severity of the stains.
Stir the solution until the potassium permanganate is fully dissolved.
Soak the white linen blazer in the solution for at least an hour.
Rinse the blazer thoroughly under cool running water until all traces of the potassium permanganate have been removed.
Wash the blazer in a washing machine with a mild detergent and warm water.
Hang the blazer to dry in a well-ventilated area.
It’s important to be cautious when using potassium permanganate, as it can cause irritation to the skin and eyes. Wear gloves and eye protection when handling the solution. Additionally, be sure to rinse the blazer thoroughly to remove all traces of the potassium permanganate.
