There is no one-size-fits-all answer to this question, as the best way to clean carpets depends on the dirt, dust, pet dander, and allergens present in the carpeting. However, one approach that may be effective is steaming. This method heats water in a steam cleaner and then uses it to clean the carpeting. It is a gentle way to clean your carpets and can also remove dust, pet dander, and other allergens.
