Engineered For The Job. Not The Laundry Aisle.
Three things make Blackwater different. None of them are 'fresh linen scent'.
Built For Mess
Engineered for diesel, grease, and shop grime — not yoga pants. Petroleum-cutting surfactants, enzymes for set-in sweat odor.
One Wash. One Cycle.
Concentrated formula cuts through embedded grime in a single load. Stop rewashing the same shirt.
Gear-Safe Formula
No bleach, no softener, no optical brighteners. Does not restore, confer, or guarantee FR. Follow the garment tag.
Everything Inside The Bottle.
The technical answers you'd ask if we were standing on a job-site.
Why Blackwater?
Comprehensive. Engineered for petroleum oils, embedded grease, smoke, and set-in sweat odor.
Gear-safe. No bleach, no softener, no optical brighteners — the three things that compromise FR ratings and degrade reflective tape.
Formula & Ingredients
Petroleum-cutting surfactants, enzymes for set-in protein soils (sweat, skin oil), pH-balanced builders to lift mineral grit (concrete dust, hydraulic fluid). No dyes, no synthetic florals, no fabric softeners.
FR & High-Vis Safety
Formulated without bleach, fabric softeners, or optical brighteners. Does not restore, confer, or guarantee FR. Follow the garment tag.
We leave out chlorine bleach, optical brighteners, and silicone-based softeners. Always follow the garment tag.
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.
Care & Storage
Store below 90°F out of direct sunlight. Shelf-stable for 24 months from manufacture date. Recyclable HDPE bottle (#2).
Sustainability
Concentrated formula means fewer trucks shipping water, less plastic per load. We're working toward refill pouches and a take-back program for empty bottles.
Any Last Questions?
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.
Will it actually get diesel and gas smell out?
That's the specific problem it was built for. Petroleum odor sticks because fuel bonds to fabric fibers — most detergents mask it with fragrance, so the smell returns as soon as you heat up and sweat. Blackwater's surfactants lift the petroleum out instead of covering it. For heavily contaminated gear, add the Grease & Odor Booster to the same load.
How many loads in a bottle?
32 loads from a 32 oz bottle at 1 oz per load. Subscribe & Save is 10% off. Because it's concentrated and cuts grease in one cycle, you also stop paying for the rewash.
Can I subscribe and save?
Yes. Choose Subscribe & Save on any product page — 10% off every order, delivered every 1, 2, or 3 months. Pause, skip, or cancel anytime from your account. No fees, no minimum number of orders.
Do I need the Booster too, or is detergent enough?
Detergent handles the everyday load on its own. Add the others when conditions call for it:
Grease & Odor Booster — in-wash additive for set-in diesel odor and embedded shop grease.
The Workwear Kit pairs detergent and booster at a discount if you want both.
Does it work in cold water and HE machines?
Yes to both. It's HE-compatible and works in any washer — front-loader, top-loader, or an old machine in the shop. It performs in cold, warm, or hot; you'll get the fullest surfactant action on warm. One capful per load, no extra rinse cycle needed.
What if it doesn't work on my gear?
30-day money-back guarantee — full refund on your first bottle, no return shipping games. If it can't handle what you put in front of it, we'd rather hear about it than keep your money.
