Lestoil Heavy Duty Degreaser — Original Multi-Purpose Cleaner
Lestoil degreaser is a concentrated petroleum-based cleaner designed to tackle the toughest grease, oil, tar, and grime. We’ve been making this original formula since 1933, and it remains one of the most effective degreasers for laundry pre-treatment, floor cleaning, engine parts, tools, and industrial equipment.
Pour Lestoil directly onto grease stains, oil spots, or heavily soiled areas of work clothing before washing. Let it sit for five to ten minutes so the petroleum solvents can penetrate the fibers and break down the oil. Then launder as usual with your regular detergent — the stain lifts away in the wash cycle.
Dilution ratios for floors and hard surfaces
Mix one-quarter cup of Lestoil per gallon of warm water for routine mopping on tile, vinyl, or sealed concrete. This ratio cuts through kitchen grease, tracked-in oil, and everyday dirt without leaving residue. For garage floors or workshop concrete with heavy oil stains, increase the concentration to one-half cup per gallon and scrub with a stiff brush.
Lestoil does not require rinsing on most surfaces, but if you’re cleaning areas where pets or children play, a quick rinse with plain water gives extra peace of mind. The pine scent fades as the surface dries, leaving no sticky film. We use the same multi-purpose cleaner formula across all bottle sizes, so dilution guidelines stay consistent whether you buy the 28 oz or 48 oz bottle.
Engine degreasing and automotive cleaning
Underhood degreasing
Apply Lestoil full-strength to engine blocks, transmission cases, and undercarriage components to dissolve caked-on grease and road grime. Spray or brush it onto the surface, let it dwell for ten minutes, then rinse with a pressure washer or garden hose. The petroleum base cuts through oil films that water-based cleaners leave behind.
Tools and equipment
Soak wrenches, sockets, and metal parts in a bucket with one part Lestoil to four parts water. After fifteen minutes, scrub with a brush and rinse — the degreaser lifts rust preventatives, cutting fluids, and shop grime. Lestoil also cleans paint rollers, brushes, and spray equipment when you’re working with oil-based coatings.

Common questions about Lestoil heavy duty degreaser
Yes. Add one-quarter cup of Lestoil to the wash water along with your regular detergent for heavily soiled loads, or apply it directly to stains as a pre-treatment before washing. Do not pour it into the bleach or fabric softener dispenser — add it to the drum with the clothes. Lestoil is safe for septic systems when used as directed.
Lestoil works on tile, vinyl, sealed concrete, and most hard surfaces. Avoid using it on unsealed wood, marble, or natural stone, as the petroleum solvents can damage porous materials. Always test in an inconspicuous area first if you are unsure about your flooring type. For best results, dilute one-quarter cup per gallon of warm water.
Dish soap is a surfactant-based detergent that works well on fresh grease and light oils. Lestoil is a petroleum solvent that dissolves set-in grease, motor oil, tar, and industrial grime that detergents cannot break down. If dish soap leaves a residue or fails to remove the stain, Lestoil will cut through it because it attacks oil-based contaminants at a molecular level.
Rinsing is not required on most surfaces when you use the recommended dilution of one-quarter cup per gallon. The product dries residue-free. If you are cleaning areas where children or pets spend time on the floor, you may rinse with plain water for extra peace of mind. For heavy-duty jobs with higher concentrations, rinsing helps remove any remaining solvent film.
Yes. Lestoil dissolves many types of adhesive residue, tape marks, and dried latex paint. Apply it full-strength, let it sit for a few minutes, then scrub with a brush or rag. For stubborn adhesives, repeat the application. It also cleans up wet oil-based paint from tools and equipment, though mineral spirits may work faster for large paint cleanup jobs.
Lestoil is manufactured in the United States. We have produced this original petroleum-based formula domestically since 1933, and the product remains a trusted choice for heavy-duty cleaning across households, workshops, and industrial facilities.
A 48 oz bottle lasts several months for most households because you dilute it for nearly every task. One-quarter cup treats a load of laundry or cleans a gallon of mop water, so you get dozens of uses per bottle. If you are using it full-strength for engine degreasing or stain pre-treatment, consumption increases, but even then one bottle handles many jobs before you need to reorder.
