Often, coin-operated laundries are safe ventures. This is because people have to wash clothes daily or weekly. They go to places where they can pay to have their clothes cleaned. These places use commercial-grade washing machines and dryers. To use these machines, you need coins to operate them. Places like these are known as coin-op laundries, Laundromats, or self-service laundries. They are usually called coin laundry. These ventures may also provide dry cleaning services.
