AR Blue Clean AR64511 Pump Saver 16 oz

Pump Saver for Plunger Pumps

The AR Blue Clean AR64511 Pump Saver is a 16 oz formula designed to protect pressure washer plunger pumps during storage. It prevents internal corrosion and freeze damage while keeping seals lubricated. The plastic bottle includes an applicator for direct connection to the pump inlet. It is intended for owners of pressure washers who store equipment seasonally.

Replaces Seasonal Drain-Only Routines

Using this fluid upgrades a basic drain-and-store method by adding active corrosion inhibition and lubrication. The jump is worth it when the pump sits idle for weeks or months in unheated spaces where residual water could freeze. It protects metal surfaces and seal elastomers that plain draining leaves exposed to air and moisture. The fluid is rated for a maximum temperature of 160 degrees F.

Check Inlet Thread and Pump Type

Before ordering, confirm the pressure washer uses a plunger pump with a 3/4 in female NPT inlet thread. The applicator connects directly to this fitting. Verify the pump materials are compatible with the fluid and that the unit can be flushed before the next use. This product is not for buyers who need a cleaner or descaler rather than a storage protectant.
