Saltwater Pools Eat Cleaner Bearings and Pins First

In saltwater pools, the bearings and pivot pins on a pressure-side cleaner are the first things to corrode — even if the pool is perfectly bonded.

Saltwater is a great electrolyte. That means any two different metals on the cleaner form a tiny battery. Bonding stops big dangerous voltage differences in the pool, but it doesn’t stop small galvanic corrosion happening right inside a brass bushing or around a stainless pin. Add chlorine and low pH to the mix
