In most laundromats, public washers typically do not use the same detergent for everyone's clothes. Each customer is responsible for bringing their own laundry detergent or purchasing detergent from the laundromat on-site.
Laundromats usually provide commercial-grade washing machines, which are designed to handle a variety of detergent types, including powder, liquid, or pods. Customers are free to use their preferred detergent and follow the manufacturer's guidelines for the appropriate amount to use based on the size of their laundry load.
Using personal detergents ensures that customers can choose products that meet their specific laundry needs, such as those suitable for sensitive skin, hypoallergenic options, or eco-friendly detergents.
It's important to note that while the laundromat provides the washing machines and often offers vending machines or detergent dispensers, customers are generally responsible for bringing their own detergent and other laundry products.
