We clean it by a special vacuum cleaner for bed / mattress, called RAYCOP. It is a special product for UV disinfection and dust removal.
However, it is difficult to remove the stains on the mattress / carpet. Also please note that only fabric sofas can be cleaned.
If you ordered this special service, if you can put alcohol (disinfectant alcohol, soju, vodka, etc.) in the sprayer and spray it on carpet, mattress, or sofas on the day before the service, all the house mites that are breeding inside will die. After that if we use RAYCOP vacuum cleaner, it is almost possible to exterminate house mites.
