We had some blinds on our windows that had been up for 10 years and had never been cleaned. We tried cleaning them and it was ridiculous, it was getting all kinds of dust in the air. So we decided to call someone to do it. They called to ask if we had water available and we didn't really, only in the bathrooms. So they took the blinds down, took them with them, and brought them back 2 days later. They had the blinds looking and operating like new. We were in and out quickly, without disrupting anything.
