Do you spend hundreds of rubles on cleaning products, and the stains return within a day?
It turns out that the secret to perfect carpets is hidden by professional cleaning companies.
A study in the Journal of Applied Microbiology found that a mixture of 3% hydrogen peroxide and baby shampoo removed bacteria and grease 98% more effectively than expensive sprays.

Cleaning master Anton Lebedev admitted in an interview with Clean Home Magazine :
"We are taught never to reveal this recipe - it will deprive the business of profit."
How does it work? Mix 100 ml of peroxide, 50 ml of shampoo and 200 ml of warm water. Apply to the stain, scrub with a brush and leave for 10 minutes.
User Svetlana from Omsk shares:
"I got out a 5 year old wine stain! The cleaners suggested throwing out the carpet, but the method worked."
Important : Do not use peroxide higher than 3% - it can discolor the fabric. For wool carpets, add 1 tbsp. glycerin to protect the fibers.
The method's history goes back to the 1950s, when American hospitals used peroxide to disinfect carpets.
Archived documents from the National Institutes of Health confirm that during flu epidemics, this solution was used to treat floors to stop the spread of viruses.
But in the 1980s, household chemical manufacturers began lobbying for a ban on “folk” methods.
Corporate scandal expert Mark Thomas writes in his book Dirty Secrets :
"They paid scientists to publish fake studies about the harm of peroxide to tissue."
Additional life hack: to eliminate the smell of animal urine, add 1 teaspoon of baking soda to the solution.
Veterinarian Anna Kuznetsova explains:
"The baking soda neutralizes the ammonia, and the peroxide kills the bacteria that cause the odor."
User @DogLover :
"After the puppy peed on the carpet, I thought I'd have to change it. A mixture of hydrogen peroxide and soda saved it - not even a trace!"
Do not use this method on silk carpets - peroxide can destroy the structure of the threads. For delicate materials, use a solution of 100 ml of milk and 1 tbsp. of starch.
A study in Textile Care Journal found that lactic enzymes gently remove stains without causing damage.
