PrimoChill System Soap DIY Cooling Loop Cleaner

SKU CH-SHNF-RP5G6

A non-toxic, multi-purpose soap for cleaning water-cooling parts, lubricating rigid-tube bending and flushing coolant residue from loops

  • Product typeCPU Block
  • Cleans water-cooling parts before assembly with a few drops in warm water
  • Lubricates rigid-tube bending cord for smooth insertion without oil residue
  • Gentle non-toxic formula removes stubborn coolant deposits inside a filled loop
  • Safe hand soap for post-build cleanup after long sessions
  • Multi-purpose tool-box addition for DIY liquid-cooling maintenance

Multi-Purpose Loop Maintenance Fluid

PrimoChill System Soap is a concentrated cleaning and lubrication agent designed for custom water-cooling builders. It prepares new components, assists rigid-tube bending and flushes aged coolant residue from an assembled loop. The non-toxic formula also doubles as a hand cleaner after a build session.

Build-Phase Utility

A few drops in warm water create a scrubbing solution that removes manufacturing oils from blocks, radiators and fittings before first use. The same mixture lubricates bending cords so they slide inside rigid tubing without leaving petroleum residue. During a loop flush, adding drops to heated distilled water while the pump runs dislodges stubborn coolant deposits.

Material Compatibility Limit

The product is explicitly not compatible with aluminium water-cooling parts, so loops containing aluminium radiators or blocks must avoid it. Over-dosing during a flush creates excessive foam that can impair pump operation. It is a consumable maintenance fluid, not a coolant, and offers no corrosion inhibition or biocide action for long-term loop filling.

Questions about this item

How long does the PrimoChill System Soap last before I need to replace the bottle?

A single bottle provides enough concentrate for many cleaning sessions because only a few drops are required per use, whether pre-cleaning components, lubricating bending cord, or flushing a loop.

What limits how effectively the soap can clean a heavily contaminated loop?

The product is described as a gentle, non-toxic cleaner; heavy or baked-on coolant residue may require multiple hot-water flush cycles with fresh drops added each time to fully clear the system.

Does the soap create foam or heat issues when circulating through the pump all day?

The manufacturer warns that adding too much soap while the pump runs will cause a foam fest, so only a couple of drops should be used during a heated flush to avoid excessive foaming.
