How to Remove Diesel & Fuel Oil Stains from Clothes

Diesel is a high-flash hydrocarbon that bonds tightly to cotton, polyester and denim fibres — and the smell can linger for weeks after a normal wash. Luniva Pro Formula is a heavy-duty solvent-action degreaser engineered for fuel, oil and grease on workwear, overalls and chef whites. It dissolves the hydrocarbon carrier in 1–3 minutes so a standard 40°C wash flushes the residue out cleanly. Bleach-free, colour-safe on most workwear fabrics.

Why diesel resists normal detergent

Diesel is a long-chain hydrocarbon. Water-based detergents simply slide off it, and the wash cycle smears the fuel across the whole garment — leaving the stain plus the odour. You need a solvent-action degreaser that breaks the hydrocarbon bond before the wash starts. That is exactly what Pro Formula is built for.

How to use Luniva on diesel & fuel stains · pro formula

Step 1 — Spray Pro Formula directly: Saturate the diesel stain until visibly wet. Work in a ventilated area. No rubbing.
Step 2 — Wait 1–3 minutes: Pro Formula's solvent-action chemistry dissolves the diesel carrier so it lifts away from the fibre.
Step 3 — Wash separately as normal, following the garment care label: Wash the garment on its own (never with non-workwear). Air-dry first; inspect before any tumble-dry.

Compliance note: Based on controlled laboratory testing. Performance may vary by stain age, fabric type and wash conditions.

Frequently asked questions

Does Luniva Pro Formula remove the diesel smell as well as the stain?

Yes. Pro Formula dissolves the hydrocarbon carrier itself, which is what holds the smell. Spray, wait 1–3 minutes, wash as normal, following the garment care label, and air-dry — the odour lifts with the stain.

Is Pro Formula safe on hi-vis workwear?

Yes on standard hi-vis polycotton. For garments with reflective tape or membrane coatings, spot-test on a hidden seam first and avoid spraying directly onto the tape.

Can I use Pro Formula on red diesel and heating oil stains?

Yes. Red diesel and home heating oil are the same hydrocarbon family — treat exactly as standard diesel: spray, wait 1–3 minutes, wash separately as normal, following the garment care label.

Why is Pro Formula different from your pink Enzyme bottle?

The pink Enzyme bottle is built for everyday protein and food stains (blood, sweat, curry, coffee). Pro Formula is a solvent-action degreaser engineered for oil, grease, diesel and workwear. Two different stain families, two different chemistries.

Do I need to wash diesel clothing separately?

Yes — always. Even after Pro Formula treatment, washing diesel garments on their own protects your other laundry from any trace residue in the drum.
