MirrorXponge is a revolutionary polishing tool independently developed by Cool Tech.
Traditional polishing methods rely on compounds (abrasives and polishing agents), which often result in cloudy finishes and surface contamination.
Mirror Sponge achieves mirror finishes using only water by utilizing a unique structure and material composition.
This reduces polishing defects and contamination, helping to improve both surface quality and production efficiency.
Mirror Polishing with Water Only MirrorXponge

What is MirrorXponge?

Polishes with Just Water
Mirror Sponge achieves a mirror-like finish without the need for compounds, paste, or buffing agents.
It leaves no residue on the surface, has no chemical odor, and poses no health risks to users.
Boosts Productivity by Reducing Steps
With its high-performance polishing ability, Mirror Sponge dramatically shortens polishing time.
It is resistant to clogging and keeps itself clean, reducing both setup and cleanup time,
making process improvements easier to achieve.
Removes Rust and Grime Without Scratching the Surface
Conventional methods often scratch the underlying material when removing rust or stains.
Mirror Sponge gently eliminates rust and grime while enhancing the surface gloss —
all without damaging the base material.
MirrorXponge polishing data
Comparative tests were conducted using MirrorXponge and traditional buffing tools, evaluating changes in surface roughness and gloss over polishing time.
・MirrorXponge demonstrated a gloss level difference of over 50° after just 60 seconds compared to untreated surfaces.
・It achieved the final surface roughness level of competing products in only one-fourth of the time, significantly improving process speed.
