There are two primary styles of hoses suitable for car cleaning traditional rubber hoses and newer lightweight options like expandable or PVC hoses. Rubber hoses are durable and can withstand high pressure, making them a great choice for heavy-duty washing. However, they can be cumbersome to handle. On the other hand, expandable hoses offer the advantage of portability and ease of storage. They expand when filled with water and retract when empty, making them ideal for those with limited storage space.

Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.
