Metra Pumice Cleaning Stone with Handle 4 Pack

Metra Pumice Stone Four-Pack

The Metra pumice stone four-pack supplies four natural abrasive blocks each fitted with a heavy-duty plastic handle. The stones measure 5.25 by 1.5 by 1.5 inches and weigh 0.13 pounds each. They are intended for household buyers who need a chemical-free way to remove calcium, lime and hard-water deposits from porcelain, pool tile, barbecue grills and steel fixtures. The set is not suited for anyone who requires a powered scrubber or a liquid descaler for large commercial installations.

Sustained Cleaning Action

Because the pumice wears down gradually, each stone maintains its abrasive surface through repeated sessions without the performance drop-off seen with single-use pads. The finer grit reduces the risk of scratching delicate glazing during extended use on toilet bowls or pool walls. The handle keeps hands clear of the residue so the user can maintain consistent pressure for the duration of the job. The stone can also be reshaped on the fly to reach tight corners that otherwise stay dirty.

Natural Pumice Limits

The 100 percent natural pumice contains no added scent or synthetic binder, so it dissolves harmlessly in water and is safe for plants and animals. Its gentle abrasive action works only on surfaces harder than the stone itself; softer acrylics or polished marble can be marked if pressure is excessive. The block cannot dissolve heavy scale instantly — stubborn rings require multiple gentle passes rather than a single aggressive scrub. The plastic handle is not heat-rated, so the tool must not be used on hot grill grates.
