Interestingly enough, some people have allergic reactions to carpets after they have been cleaned. The risk is higher when you clean the carpets on your own with harsh cleaning chemicals, allergy-causing fumes, and rough methods. Some people have allergy reactions to regular cleaning detergents with perfumes, so hiring professionals is wise because they can use hypoallergenic compounds. An allergic reaction could happen when you react to loose carpet fabric particles ripped off throughout the cleaning procedure. It’s not common, but it does happen if rough cleaning techniques are used with fragile fibers.
