Radiator Cleaning Kit for Custom Loops

The PrimoChill Rad Clean kit provides a water-based, non-toxic concentrate for flushing new or used radiators before they enter a custom cooling loop. It includes a 2oz bottle, two plastic fittings with O-rings, and a threaded funnel for straightforward preparation.

Usage Limits and Metal Compatibility

The solution is formulated for the internal metals found in radiators only and must not be used on nickel-plated components. Each treatment requires mixing half the bottle with 32oz of distilled, RO, or DI water, then shaking the sealed radiator and letting it sit for one hour.

Replaces Manual Flushing and Harsh Chemicals

This kit replaces time-consuming manual rinsing and aggressive chemical cleaners that can damage seals, acrylic, or other loop parts. The jump is worth it when building a new loop or servicing an existing one where a thorough, component-safe interior scrub is needed without special protective gear.

Questions about this item

Which size of the PrimoChill Rad Clean kit should I pick?

The kit is supplied as a single 2oz bottle that is designed to be mixed with 32oz of distilled or DI water, so there is only one capacity to choose.

What does the 32oz mix volume mean when I use the cleaner in my loop?

You dilute half the bottle into 32oz of distilled or DI water, fill the radiator, seal it with the included plastic fittings, shake, let it sit for one hour, then drain and flush thoroughly.

What interface or standard does the cleaning kit use and what does it limit?

The kit includes two plastic fittings with O‑rings and a threaded funnel that connect to standard radiator ports; the cleaner is compatible only with radiator metals and must not be used on nickel‑plated components.
