How to Remove Grease Stains with Lestoil: A Step-by-Step Guide for Tough Oil and Grease
Grease stains are among the most stubborn laundry challenges you’ll face. Whether it’s a splash of cooking oil, a smear of motor grease from a DIY project, or butter from dinner, grease clings to fabric fibers in ways that ordinary detergent can’t touch.
That’s where we come in. For decades, Lestoil for grease stains has been the go-to solution for tough oil-based marks that other products leave behind. Our heavy-duty formula breaks down petroleum-based and organic greases at the molecular level, lifting them out of fabric instead of just spreading them around. In this guide, we’ll walk you through exactly how to use Lestoil to tackle grease stains on clothing, upholstery, and other washable fabrics—so you can save your favorite garments instead of throwing them out.
Why Grease Stains Are Different from Other Stains
Grease doesn’t dissolve in water the way food dyes or dirt do. Oil molecules repel water, which means tossing a greasy shirt into the wash with regular detergent often just sets the stain deeper into the fibers.
Successful grease removal requires a solvent-based cleaner that can break the molecular bonds holding oil to fabric. Lestoil’s petroleum distillate formula does exactly that—it penetrates the grease, emulsifies it, and allows water to carry it away during the wash cycle. That’s why pre-treating with a product specifically designed for oil-based stains makes all the difference between a clean garment and a permanent mark.
The Lestoil Pre-Treatment Method for Grease Stains
Start by laying the stained garment flat on a clean work surface with the stain facing up. Pour a small amount of Lestoil directly onto the grease mark—enough to saturate the fabric but not soak through to the other side.
Work the Product Into the Fabric
Use your fingers or an old toothbrush to gently work the Lestoil into the stain using circular motions. You’ll notice the product beginning to break down the grease almost immediately. Let the treated garment sit for at least 15 minutes; for older or set-in stains, allow 30 minutes to an hour.
Wash as Usual
After the pre-treatment period, launder the item in the hottest water safe for the fabric according to the care label. Add your regular detergent to the machine—the combination of Lestoil’s grease-cutting power and detergent’s cleaning action will lift the stain completely. Check the garment before drying; heat can set any remaining traces, so if a faint shadow remains, repeat the treatment and wash again.
What Types of Grease Stains Lestoil Handles Best
We’ve seen Lestoil work on everything from bacon grease and salad dressing to automotive oil and chain lube. Cooking oils—olive oil, vegetable oil, butter—respond especially well because they’re relatively fresh and haven’t had time to oxidize deeply into fibers.
Motor oil, hydraulic fluid, and bike chain grease are tougher but still manageable with our formula. The key is treating them as soon as possible. The same principles that make using Lestoil for laundry stains effective across categories apply here: the cleaner needs contact time with the oil, and pre-treatment always outperforms throwing a stained item straight into the wash. Even old grease marks that have been through the dryer can sometimes be salvaged with a concentrated Lestoil application and a long soak before washing.
Tips for Treating Grease on Delicate and Non-Washable Fabrics
Not every greasy item can go straight into the washing machine. For delicate fabrics like silk or wool, test Lestoil on an inconspicuous seam or hem first to ensure colorfastness.
If the fabric tolerates the product, apply a small amount to the stain, blot gently with a clean white cloth, and then sponge the area with cool water to rinse. Repeat as needed, working from the outside of the stain inward to avoid spreading. For upholstery or items labeled dry-clean-only, consider spot-treating with Lestoil and then taking the piece to a professional cleaner—mention that you’ve pre-treated it so they know what they’re working with. According to stain removal research, solvent-based treatments are consistently more effective on oil-based marks than water-based detergents alone, which is why our petroleum distillate formula performs where others don’t.
Get Grease Out for Good
Grease stains don’t have to mean the end of your favorite shirt or work pants. With Lestoil’s proven solvent-based formula and the right pre-treatment technique, you can lift even stubborn oil and grease from fabric and restore your laundry to like-new condition.
The key is acting quickly, giving the product time to work, and washing in hot water when the fabric allows it. We’ve spent decades refining our formula to tackle the toughest cleaning jobs, and grease removal remains one of our core strengths. Keep a bottle in your laundry room, treat stains as soon as they happen, and you’ll save more clothes than you thought possible.
Notes
Yes, Lestoil is safe for colorfast fabrics. We recommend testing on a hidden seam first if you’re concerned about a particular garment. The product is designed to target grease, not dyes, so it won’t bleach or discolor properly set colors.
Always follow the care label’s temperature guidelines when washing treated items.
For fresh grease stains, 15 to 20 minutes of contact time is usually sufficient. For older or set-in stains, let the product sit for 30 minutes to an hour.
The longer contact time allows the solvent to fully penetrate and emulsify the grease. Just make sure the fabric stays damp with product during that period—if it dries out, add a bit more Lestoil.
No, Lestoil rinses away completely during the wash cycle when used as directed. Apply it only to the stained area before loading the garment into the machine, and wash with your regular detergent.
The product is formulated to break down and disperse in water, so it won’t coat your machine’s drum or leave buildup on other laundry items.
Yes, though heat-set stains are more challenging. Saturate the stain thoroughly with Lestoil and let it sit for at least an hour, working the product into the fabric with a brush.
Wash in the hottest water safe for the garment and check before drying again. You may need to repeat the treatment, but many heat-set grease stains can still be lifted with persistent pre-treatment.
Lestoil is a strong cleaner and should be used with care. Keep it out of reach of children and pets, and use it in a well-ventilated area.
Once a treated garment has been washed and rinsed thoroughly, it’s perfectly safe to wear. Always follow label instructions and avoid direct skin contact with the concentrated product—wear gloves if you have sensitive skin.
