You can clean painted walls with warm water and an all-purpose cleaner, but to get rid of smoke stains and smells from the wall, you should spray warm vinegar on the stains or ammonia mixed with water. For tough cigarette stains, use trisodium phosphate to get rid of them.
Detailed maids came to clean a unit right before I staged it to be sold. They cleaned the appliances, cabinets, blinds, floor, etc. They were diligent and detail-oriented. Would recommend them.
Isabella and Samantha did SUCH an amazing job cleaning my condo to prep it for my sale. They were efficient and so friendly. They really made it sparkle. Would definitely recommend 10/10. Thank you!!
