For Farmers & Ag

Hydraulic Fluid, Diesel, And The Barn. All In One Load.

A busted hose on the combine, diesel down the leg at the fuel tank, grease from the driveline, silage, and whatever the barn added. Then it all goes in together — usually during the two weeks you have the least time to deal with it.

Blackwater is built for petroleum and organic soil in the same load, and it rinses clean — no softener film holding odor in the fiber.

  • Hydraulic fluid, diesel, grease, manure, and silage
  • Cuts barn odor at the source instead of covering it
  • Safe on coveralls, insulated bibs, and duck canvas
  • 160 oz refill sized for harvest

What You're Actually Fighting

Three Things Killing Your Coveralls.

None of them are solved by a stronger scent.

02

Hydraulic Fluid & Diesel

Equipment oil is the hardest soil on the farm. It soaks into canvas, survives a normal cycle, and comes back to the nose the moment the fabric warms up.

03

Barn & Silage Odor

Manure and silage odor come from organic soil left in the weave. Fragrance covers it for an hour, then body heat brings it straight back.

04

Everything At Once

Farm laundry is petroleum and organic soil in the same load — the exact combination household detergent handles worst.

How to wash farm work clothes

Farm laundry is the hardest mix there is: petroleum from equipment, organic soil from livestock and silage, plus mineral dust from the field — frequently in the same pair of coveralls.

1. Separate the chemical clothes

Clothing worn while handling crop-protection products should always be washed separately from everything else — separate from family laundry and separate from your other work clothes. This is standard guidance from extension services and product labels. Follow the specific instructions on the product label you were handling; some garments are designated for disposal rather than laundering.

2. Shake out dry material outside

Field dust, chaff, and dried mud come off easier dry. Wetting them first sets the soil into the weave.

3. Pre-treat hydraulic fluid and grease

Equipment oil is the soil most likely to survive a cycle. Hit it with degreaser, work it in, and wait 5–10 minutes before washing.

4. Wash warm with a clean-rinsing detergent

Warm water releases petroleum so the surfactants can carry it out. Skip fabric softener — it coats the fiber and traps barn odor rather than removing it.

5. Air dry and check before heat

If diesel or barn odor is still there after air drying, the soil is still in the fabric. Rewash with the Booster before it goes anywhere near a dryer — heat sets both.

Harvest volume

During harvest you are not doing laundry twice. The 160 oz refill runs roughly 320 loads — the right buy heading into a season where the machine runs every night and nobody has time to babysit a stain.

Barn odor is trapped soil

Manure and silage odor persist because organic material is still in the fiber. Enzymes and real surfactants break it down; fragrance just layers over it. That is why the smell reappears the moment you warm up in the cab.

Built for equipment oil and the barn. In the same load.

Hydraulic fluid, diesel, grease, and organic soil — out in one cycle, with nothing left behind to hold odor.

Farm Questions.

Will it get hydraulic fluid out of my coveralls?

Yes — that's the soil it was built for. Pre-treat the spot with the Degreaser, give it 5–10 minutes, then wash warm. Air dry and check before any dryer heat, since heat sets whatever is left.

What about clothes worn while spraying?

Always wash them separately — from family laundry and from your other work clothes — and follow the instructions on the specific product label you were handling. Some garments are designated for disposal rather than laundering.

We want to be straight with you: Blackwater is a detergent, not a decontamination product. We make no claims about removing crop-protection chemicals. For that, the product label and your extension service are the authority.

Why does barn smell come back after washing?

Because the organic soil is still in the fiber. Fragrance covers it until body heat in the cab releases it again. Enzymes and real surfactants break the soil down instead — add the Booster for a week's worth of barn work.

Is there a size that makes sense for harvest?

The 160 oz refill runs about 320 loads. If the machine is running every night for six weeks, that's the one to have on the shelf before you start.

How many loads in a bottle?

32 loads from a 32 oz bottle at 1 oz per load. Subscribe & Save is 10% off. The 160 oz refill is available for bigger runs.
