We had a house move in service. To be honest, the house was quite clean before we move in, but we still need some cleaning for the bathrooms and kitchens, especially the kitchen ventilator. However, after three hours of two people's working, the ventilator is still greasy, even on the outside. They wiped the kitchen counter, but after they left, I used my finger to wipe the counter to test, my finger is black and covered with l dust. They must use dirty water yo clean the counter. The couter was even cleaner before they did anything. It is a empty house, nothing is in the kitchen at all. I did not see any progress of cleaness in thr kitchen.
