Stubborn stains are all too common. Often if we can’t get the stain out on the first few tries, we let the stain become a permanent fixture of the carpet. If you have stains that won’t budge, try a baking soda and vinegar solution to remove old stains from your carpet.

How to Prepare the Baking Soda-Vinegar Mix

  1. Mix equal parts white vinegar and water in a spray bottle
  2. Add a few drops of liquid dishwashing soap to enhance the solution’s cleaning power
  3. Sprinkle baking soda generously over the stained area, ensuring full coverage
  4. Spray the vinegar solution onto the baking soda-covered stain until it starts fizzing

Application Process for Different Types of Stains

  • Coffee Stains: Let the fizzing reaction work for about five minutes before gently scrubbing with a microfiber cloth or soft-bristled brush. Then, blot the carpet dry with paper towels afterward.
  • Pet Stains: Let the solution sit longer—10-15 minutes—for urine-based stains to allow enzymes to break down proteins. Use an old toothbrush to agitate fibers during the final rinse step and ensure thorough removal of all traces. Finally, blot excess moisture away using clean towel sections as needed.

Hydrogen Peroxide Treatment for Light-Colored Carpets

Eliminate stubborn carpet stains with hydrogen peroxide and a steam vacuum machine

Hydrogen peroxide is another powerful cleaning tool that can help you remove old stains from carpet. However, before you use hydrogen peroxide to clean your carpet, there are some safety precautions you need to follow.

Safety Precautions When Handling Hydrogen Peroxide

  • Wear gloves and eye protection to avoid skin irritation and eye damage
  • Dilute the solution to no more than 3% concentration to prevent bleaching or damage to carpet fibers
  • Ensure proper ventilation by opening windows or using fans

Once you’ve taken care of these safety precautions, you are ready to eliminate those old stains.

Steam Vacuuming & Hydrogen Peroxide Treatment

  1. Mix equal parts water and hydrogen peroxide (no more than 3% concentration) in a spray bottle and shake well.
  2. Spray the stained area generously but not excessively.
  3. Gently agitate the stain with a soft-bristled brush or microfiber cloth, working from the outside edges towards the center of the spot.
  4. Let sit for about five minutes to allow the solution to penetrate the stain.
  5. Extract the solution and stain from the carpet fibers using a steam vacuum machine.

In addition to being an excellent carpet cleaning solution, hydrogen peroxide is also useful for a number of household remedies.

Using Club Soda as a Stain Remover

Club soda can remove old stains from carpet, including pet accidents and red wine spills

Club soda is found in almost every home and grocery store—which makes it one of the most accessible cleaning methods out there. Club soda is surprisingly effective when it comes to removing old stains from your carpet. Let’s explore how you can use club soda to remove stains that just won’t go away with other cleaning strategies.

How to Use Club Soda to Clean Carpet Stains

After pouring a small amount of club soda onto the stained area, wait 10-15 minutes—depending on the stain’s severity—before blotting with a microfiber cloth or paper towel.

  • Mild stains: Wait 1-2 minutes before blotting
  • Moderate stains: Wait up to 5 minutes before blotting
  • Tough stains: Apply multiple applications of club soda and wait up to 15 minutes before blotting

Club soda won’t harm your carpet material, making it a great alternative to harsh chemicals. Remember to always test any cleaning solution on a small, inconspicuous area of your carpet before applying it to the entire stained area.

Removing Red Wine Spills With White Wine

Don’t cry over spilled red wine, neutralize it with white wine

Applying white wine over affected areas helps neutralize stain-causing tannins found within red wine, making it easier to remove. Though it may sound counterintuitive, this is an excellent method to get rid of old red wine stains.

Steps for applying White Wine on Red Wine Stains

  1. Pour white wine onto the stained area to dilute and break down the pigments in the red wine.
  2. Gently blot the stain using a clean microfiber cloth or paper towel.
  3. Repeat steps one and two until you see significant improvement in the appearance of your carpet stain.

Rinsing and Blotting

Once you’ve successfully removed most of the red-wine pigment from your carpet material, follow these rinsing tips:

  • Mix equal parts water and liquid dishwashing soap in a spray bottle.
  • Lightly mist this solution onto any remaining traces of discoloration before gently dabbing away excess moisture with another clean cloth or paper towel.
  • If needed, consider employing a steam vacuum cleaner specifically designed for commercial carpets to ensure complete removal without causing further harm to your flooring investment.
  • The Whittaker line offers various options suitable for schools, hotels, and other large-scale establishments seeking reliable equipment capable of tackling even stubborn grape juice residue.

Borax: An Effective DIY Carpet Cleaning Solution

Looking for a DIY carpet cleaner that’s gentle on your flooring material but will remove old stains from carpet? Look no further than borax.

Borax is a safe-to-use, slightly alkaline substance that is able to break down carpet stains. It does not contain any harmful chemicals, though it still should be stored and administered carefully.

How to Prepare Borax Solution for Stain Removal

  1. Mix equal parts borax and warm water in a spray bottle until fully dissolved.
  2. Add a few drops of liquid dishwashing soap to enhance the cleaning power.
  3. Gently shake the mixture before applying it to the stained area.

Applying Borax

  • Spray the solution onto the carpet stain, working from outside towards the center to prevent spreading.
  • Let it sit for 10-15 minutes to penetrate and break down stubborn particles.
  • Rinse the stain with icy H2O and blot away wetness utilizing paper towels or a microfiber cloth.
  • Air out your flooring to ensure proper drying and avoid residue.

For tough stains like grape juice or pet stains, borax is a great alternative to other carpet cleaners. It’s easy to make and won’t damage your carpet fibers.
