From the manufacturer’s Safety Data Sheet, Section 8
“No inhalation H-code at mixture level in SDS §2. Respiratory protection recommendation in SDS §8 is conditional ('an exposure assessment may be needed to decide if a respirator is required'). Water-based alkaline formula with no volatile solvents; the inhalation risk arises from spraying into enclosed engine bays where mist accumulates, not from vapor pressure. Beyond SDS: lungs tier escalated from omitted to situational because the pump-spray application into a semi-enclosed engine bay is a specific documented exposure scenario, not generic boilerplate.”

CarCareTruth's Analysis
Last reviewed May 15, 2026
TL;DR Cuts through heavy engine-bay grease at 4:1 dilution with minimal agitation — one of the stronger concentrate degreasers in the category, backed by 1,300+ reviews and an 82% five-star rate. The DANGER signal word (H314, Skin Corr. 1A) is driven by alkaline-based chemistry at pH 12.5–13.5, so wear nitrile gloves and splash goggles — the SDS chemistry makes that a requirement, not a suggestion.
What it is and how it performs
A professional-line alkaline concentrate for engine bays, tires, and wheels. At 4:1 dilution it handles baked-on motor oil and ATF residue that lighter APCs leave behind — community reports confirm one-pass removal on neglected engine bays with brush agitation. The rinse is a genuine differentiator: where many alkaline degreasers leave white film, the D108 rinses cleanly under a garden hose. At 10:1 it doubles as a tire and wheel cleaner. Available in 1-gallon and 5-gallon concentrate.
Who should buy this — and who should skip it
The right call for someone with a genuinely grimy engine bay who is comfortable working with DANGER-classified chemistry and proper PPE. Skip it for a lightly dusty engine bay — a biodegradable APC handles that without corrosive chemistry. Avoid prolonged contact on bare aluminum — the H290 metal corrosion classification is real.
Safety and environmental impact
DANGER signal word driven by H314 (Skin Corr. 1A) — the alkaline-based active pushes pH to 12.5–13.5. Nitrile gloves and splash goggles are required by the SDS chemistry. No inhalation H-codes at mixture level, but work outdoors or with garage doors open. No 2-butoxyethanol, no PFAS, no volatile solvents. Surfactant carries ingredient-level H412 (aquatic chronic 3). Amazon flags Prop 65 but no SDS §3 ingredient matches the Prop 65 list.
Frequently asked questions
What dilution ratio should I use for engine bay cleaning?▾
The label recommends 4:1 (water to product) for heavy grease and engine bay work, and 10:1 for lighter cleaning like tires and wheel wells. Community reports confirm 4:1 handles neglected engine bays in a single pass with brush agitation.
Is Meguiar's Super Degreaser safe on rubber hoses and plastic engine covers?▾
At 4:1 dilution, community reports no damage to rubber, plastic, or painted engine covers. The product is labeled Body Shop Safe. Avoid prolonged full-strength contact on bare aluminum — the H290 classification means it corrodes reactive metals.
Do I need gloves and eye protection with this degreaser?▾
Yes. The SDS classifies this product as H314 (Skin Corr. 1A) with a DANGER signal word. The alkaline-based chemistry at pH 12.5–13.5 causes severe skin burns and serious eye damage at concentrate strength. Nitrile gloves and splash goggles are required by the chemistry, not optional caution.
Can I use this on tires and wheels too?▾
Yes, at 10:1 dilution. Multiple community reviews confirm it removes road grime and brake dust effectively from tires and wheels. It also works on concrete oil stains at full strength.
What sizes is the Super Degreaser available in?▾
Available in 1-gallon (D10801) and 5-gallon (D10805) containers. Both are concentrate, so the per-ounce cost at working dilution is competitive with RTU alternatives.
