How TurboStone Works

TurboStone combines the abrasive action of pumice with the continuous rotation of a cordless drill. You guide the tool across stubborn mineral buildup while the drill supplies the repetitive scrubbing motion.

Reconstructed for Powered Use

TurboStone is made from selected pumice particles formed around an internal reinforcement and drive structure. A removable matched adapter connects the stone to a variable-speed cordless drill.

The current formulation holds the pumice together through sustained powered cleaning, providing substantially stronger shape retention than earlier TurboStone versions.

Water Throughout the Working Body

The reconstructed body contains connected spaces where water can enter and collect. Fully wetting TurboStone before use loads water into that porous structure.

During cleaning, water at the contact area helps carry loosened abrasive and mineral debris away. Keep both the stone and the surface wet, replenishing water as you work.

Durable Body, Active Working Surface

In extended, heavy-pressure demonstrations, the current formulation continued cleaning with much of its working body remaining. Gradual reshaping occurred where the stone contacted the surface.

A fine, cream-like pumice slurry can develop during use. This localized abrasive action allows the working surface to renew while the body retains its useful shape.

Put the Drill to Work

Fully wet TurboStone, establish contact at a comfortable drill speed, and adjust speed and pressure for controlled cleaning. Choose a shape that gives you access to the buildup and a useful contact area.

Check that the surface is appropriate for abrasive cleaning and test an inconspicuous area first. Keep the drill and battery out of the water.

Wet the stone. Guide the tool. Let the drill supply the motion.

Built Around a Familiar Cleaning Problem

TurboStone grew out of years of dealing with stubborn well-water mineral stains and looking for a practical way to put pumice on a drill.

That work developed into a family of cleaning shapes built around water uptake, durable construction, and access to difficult deposits—from concentrated toilet-bowl rings to broader areas of mineral buildup.

What Kind of Drill Should I Use?

TurboStone is designed for a standard variable-speed cordless drill. You do not need a special drill or professional-grade equipment.

The important part is control.

Fully wet the TurboStone, attach the included adapter, and use the speed and pressure that give you the cutting action you want. The newest formulation is built to tolerate real working pressure and retain its shape instead of rapidly shedding pumice grains.

Start at a speed that feels comfortable, then adjust from there. More speed can increase cutting action, while lower speed may give you better control in tight areas or around contours.

Avoid impact drivers. TurboStone is designed for smooth rotational power rather than hammering or impact action.

Keep the TurboStone and working surface wet during use. For pools and other wet areas, keep the drill and battery out of standing water.

The stone can take a beating.

The surface underneath it may not.
