WHY IT WORKS

The stonewash effect, without pumice sludge.

HMS Original is made to keep the abrasive character of pumice while reducing the waste and process issues that come with it.

It is hydrophobic, durable, and porous. This allows it to create consistent abrasion while reducing water absorption and sludge formation.

No pumice sludge

Reduces sludge handling and waste treatment pressure.

Lower water levels

Can be used with less water than pumice because it does not absorb water in the same way.

Consistent abrasion

Internal and external porosity helps it keep working as it wears down.

Longer-lasting

Designed for repeated industrial use.

Less garment dust

Reduces the need for heavy rinsing caused by pumice dust.

Cold-water compatible

Can support lower-energy recipes where the process allows.

Proven across different wash challenges:

Shirt-weight fabric

Using HMS Original #0, Bossa achieved clean, even abrasion on lightweight shirting fabric without compromising fabric integrity.

Lycra blend wash

High-Lycra denim can be difficult to stonewash because elastic fibers may break under physical abrasion. With HMS Original #1, both indigo and sulfur-dyed Lycra blends achieved strong stonewash effects with no fiber breakage and strong post-wash fabric strength.
