Radiator cleaning solution

PrimoChill Rad Clean is a water-based treatment for flushing new or used radiators before they enter a custom loop. The concentrate mixes with distilled water to remove manufacturing residue and debris without attacking seals, acrylic or internal metals. It is supplied as a 2 oz bottle intended for DIY cooling builds.

Builders preparing a custom loop

The fluid suits anyone assembling a water-cooling circuit who wants a non-toxic, glove-free way to pre-clean radiators. It is not compatible with nickel-plated parts or aluminium water-cooling components, so builders using those materials should look at something else.

Mix ratio decides the fill

One half of the bottle is diluted into 32 oz of distilled, RO or DI water to create the cleaning mixture. This single proportion determines whether the volume you prepare will fill your radiator completely.

Questions about this item

What comes in the box and do I need to buy anything else to use it?

The box contains a 2 oz bottle of Rad Clean concentrate. You must supply 32 oz of distilled, RO or DI water and two plastic fill-port plugs to seal the radiator during the soak.

There is only one bottle size listed; how do I know it is the right amount for my radiator?

The single 2 oz bottle is dosed at half a bottle per 32 oz of water, which treats one radiator at a time regardless of its internal volume.

What does the half-bottle-to-32-oz ratio actually do inside a radiator?

That dilution creates a non-toxic, water-based solution that safely dissolves manufacturing residue and flux from the radiator's internal metal surfaces in one hour without harming seals or acrylic.
