01

Why the full 48 hours

It pulls residue and dye staining back out of the surfaces it plated onto. That needs the full run time.

0 h48 hLonger is fine

Cut short

Residue stays behind and becomes a contaminant in your next fill.

48 hours or more

Normal use during the window is fine.

After an opaque fluidBudget for several extra flushes to clear the foam.

Use it in five steps

  1. 1

    Drain the old coolant

    Catch it in a clear bucket. It tells you what the last fill did.

  2. 2

    Mix the whole bottle

    Into a gallon of DI or distilled, or straight into the reservoir.

  3. 3

    Fill, bleed, run 48 h

    Tilt the case to clear air, then let it circulate.

  4. 4

    Flush to zero foam

    Expect extra passes after Vue or another opaque fluid.

  5. 5

    Fill next, right away

    PrimoPrep or your coolant. Never leave it on plain water.

The full story

A flush-style cleanser for a loop that has already run coolant and needs to come back to zero without a teardown. It removes debris and residue and, the part no general cleaner does, lifts colour back out of components stained by a previous fluid, leaving the system clean, clear and ready for any type of coolant.
