How to wash work clothes after sewage or septic work
This is the one trade where the laundry routine is about the household as much as the garment. The goal is simple: get the soil fully out in one cycle so nothing is left to transfer.
1. Keep it fully separate
Contaminated workwear should never share a load with household laundry — not with towels, not with the kids' clothes, not with anything. Bag it separately if it is riding home in the van.
2. Do not let it sit wet
Wet, soiled workwear sitting in a bag or a hamper multiplies odor fast. Wash it the same day when you can.
3. Pre-treat pipe dope, flux, and trap grease
These are different soils than the organic material. Hit petroleum spots with degreaser and give them 5–10 minutes before the cycle.
4. Wash warm with a clean-rinsing detergent
Warm water plus real surfactants releases organic soil and grease. Follow the garment care label — especially for FR-rated or hi-vis gear.
5. Run an extra rinse
The extra rinse is what carries the loosened soil out of the drum instead of leaving it behind. This is the step most people skip and the one that matters most here.
6. Air dry and check
If any odor remains after air drying, the soil is still in the fabric. Rewash with the Booster before it goes near dryer heat.
Keeping the machine clean
After a genuinely bad load, run an empty hot cycle before household laundry goes in. Wipe the door seal and gasket — that is where residue collects on front-loaders. A detergent that rinses clean rather than leaving softener film makes this far less of a problem.
Why fragrance is the wrong answer
Heavy-fragrance detergent is especially bad for this trade. It layers scent over organic soil that is still in the fiber. The shirt smells fine in the closet and sour an hour into the next call, because body heat releases what was never removed.
