How To Use
Heavy soil: 1 capful per load (HE compatible, all washer types).
Pre-treat: For set-in stains, apply a small amount direct to the stain and wait 5 minutes before washing.
Cold water OK: Works in cold, warm, or hot — runs best with full surfactant action at warm.

How is this different from household detergent?
Household detergent is tuned for household soil — food, dirt, body oil. Blackwater is built for workwear soil: diesel, motor oil, hydraulic fluid, machine grease, plus concrete dust, smoke, and sweat-set odor.
Is it formulated for FR and high-vis gear?
Formulated without bleach, fabric softeners, or optical brighteners. Does not restore, confer, or guarantee FR. Follow the garment tag and your employer care instructions.
How many loads in a bottle?
32 loads from a 32 oz bottle at 1 oz per load. Subscribe & Save is 10% off.
Will Subscribe & Save be available?
