Meguiar's D10801 Super Degreaser, 1 Gallon Review (2026)

What Meguiar's Super Degreaser Is

Meguiar's D10801 Super Degreaser, part of the brand's professional D108 line, is a concentrated cleaner sold here in a 1 gallon jug rather than a ready to use spray bottle. Meguiar's positions it as a fast acting formula that breaks down tough grease, grime, and dirt, and the product is designed to be diluted rather than sprayed straight from the jug. Because it ships as a concentrate, buying the gallon size mainly makes sense for anyone who plans to refill a spray bottle repeatedly, such as a detailer or an owner who cleans engine bays and wheels on a regular schedule rather than once a year.

What It Is Meant to Clean

Meguiar's markets Super Degreaser for grease and grime on engines, tires, and wheels, the kind of buildup that a normal car wash soap is not strong enough to cut through. Meguiar's own product documentation lists it for exterior surfaces, so the safest approach is to treat it as an outside the cabin cleaner for engine bays, wheel wells, tires, and similar grease prone areas rather than assuming it is meant for interior fabric or upholstery. Diluted correctly, it is strong enough to lift baked on road grime and oily residue without needing to scrub aggressively.

Concentrate Strength and Dilution

Because this is a concentrate rather than a ready to use cleaner, it needs to be mixed into a spray bottle at a strength that matches the job, lighter for routine wheel and tire cleaning and stronger for heavy engine bay grime. Meguiar's does not publish a single fixed ratio for every situation, since the right strength depends on how dirty the surface is, so it is worth testing a diluted mix on a small area first. Undiluted or overly strong mixes can be too aggressive for delicate plastics and trim, so plastics should generally be cleaned at a lighter dilution than metal or rubber.

Why the Gallon Size Makes Sense

A 1 gallon jug of concentrate goes a long way once diluted, which is the main appeal over buying several smaller ready to use bottles. It also fits how Meguiar's professional line is generally sold, as bulk concentrate meant to be portioned into working spray bottles rather than sprayed from the original container. For anyone who only degreases an engine bay once or twice a year, a smaller ready to use degreaser may be more convenient, but for detailers or enthusiasts doing this regularly, the gallon size lowers the cost per cleaning by a wide margin compared with pre-diluted sprays.

Practical Notes on Using It

Meguiar's describes the formula as residue free, meaning it is built to avoid leaving the white or chalky staining that some cheaper degreasers can leave on plastic and rubber once they dry, and it carries a pleasant herbal scent rather than a harsh solvent smell. Because it is a concentrate, a funnel and a few labeled spray bottles make the gallon far more practical to use day to day than trying to pour straight from the jug. As with any degreaser, rinsing the treated area afterward and avoiding contact with unsealed paint or bare metal parts for extended periods is good practice. Keeping the concentrate in its original jug in a cool spot away from direct sun also helps it last, since a gallon bought once can realistically cover a full season of engine bay and wheel well cleaning for a typical home garage.
