From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8 specifies goggles for PPE, and §4 notes 'Causes serious eye irritation' in first-aid context · however, SDS §2 classifies the product as 'Not classified' with no H318 or H319 GHS codes. The eye-irritation mention is in the first-aid section only, not a formal GHS classification. At RTU (spray) strength, pH 7.5 neutral chemistry does not warrant eye protection for normal detailing use; situational for concentrate-handling or splash scenarios.”

TL;DR A safe, residue-free interior cleaner that's broadly trusted by owners, with pH-neutral chemistry that won't strip coatings or haze tint. Not the strongest degreaser at RTU strength, but easy to live with on any surface. There's a California Prop 65 warning for trace contaminants · not the cleaning actives · that's worth understanding.
Chemical Guys Nonsense is a pH-balanced (7.5) all-surface cleaner designed to leave nothing behind. The formula clears vinyl outgassing film, dust, and light interior soils in one pass · dashboards, door panels, steering wheels, fabric seats, plastic trim. At RTU strength it's not a degreaser; for heavy engine bay work or tire cleaning, dilute the 1-gallon concentrate at 4:1 to 8:1 instead. The standout feature is surface compatibility: the neutral pH means it won't strip wax, degrade ceramic coatings, or haze aftermarket tint film · surfaces where alkaline APCs create real risk. Community evidence from r/AutoDetailing and Autogeek consistently confirms this, making Nonsense the go-to recommendation when vehicle protection has to be preserved.
Buy it if you're doing regular interior maintenance and want a single-bottle solution that works on every surface without checking compatibility first. The 16 oz spray is ready to use out of the box; the 1-gallon concentrate is the better buy if you detail multiple cars. Skip it if heavy degreasing is the priority · a dedicated alkaline APC or engine degreaser will cut stubborn grease faster. Also skip it if you're avoiding products with California Prop 65 warnings, even for trace contaminants.
The SDS §2 classifies Nonsense as "Not classified" under GHS · no hazard codes, no signal word. The only formal safety flag is a California Proposition 65 warning for Myrcene and 1,4-Dioxane, both present as trace-level contaminants rather than intentional cleaning ingredients. Myrcene is a terpene listed for cancer and reproductive harm; 1,4-Dioxane is a processing byproduct from surfactant manufacturing, also listed for cancer. Neither triggers a GHS hazard category at the concentrations found in this formula. No PPE is required for normal interior detailing use at RTU strength; gloves are the SDS §8 guidance if handling the concentrate at full strength. The formula contains a glycol-ether co-solvent; keep spent microfibers from going directly to storm drains, and rinse towels in a wastewater-connected sink.
Community consensus on r/AutoDetailing confirms Nonsense is safe on ceramic coatings, PPF, and vinyl wrap at RTU strength. The pH-neutral formula (7.5) avoids the alkaline chemistry that can degrade hydrophobic coating layers. Multiple forum threads specifically recommend Nonsense for ceramic-coated vehicles as a maintenance interior cleaner.
The Prop 65 warning covers two trace-level substances: Myrcene (a terpene listed for cancer and reproductive harm) and 1,4-Dioxane (a process contaminant from surfactant manufacturing, listed for cancer). Neither is an intentional cleaning ingredient. The SDS §2 classifies the product as 'Not classified' under GHS · no formal hazard categories apply. The warning is required by California law whenever these substances are present above trace thresholds, regardless of actual exposure risk from normal use.
Yes. The 1-gallon SPI_993 concentrate dilutes 10:1 to 20:1 for general cleaning (stronger ratios for greasy surfaces or engine bay, higher dilution for delicate interior surfaces). The 16 oz spray SKU is sold ready-to-use. Detailing community threads on Autogeek and r/AutoDetailing recommend 10:1 dilution from concentrate for interior work, with the spray SKU used as-is for light maintenance cleaning.
Community testing consistently confirms no residue or sheen at RTU strength on vinyl, plastic, and leather surfaces. The product name ('Nonsense · Invinsible Super Cleaner') directly references the no-residue claim. A large base of long-term owner reviews supports this: residue complaints are rare and typically associated with using too much product in one application.
At RTU strength, Nonsense handles light engine bay film and dust effectively. For heavy grease or oil deposits, the 1-gallon concentrate diluted 4:1 to 8:1 is more appropriate · community threads on Autogeek and DetInfo confirm effective engine bay cleaning at stronger dilutions. RTU strength is optimized for interior surfaces, not heavy degreasing.

Detailing PPE: When You Actually Need Gloves or a Respirator
Most weekend car care needs zero PPE. A small list of chemistries (fluoride wheel acids, isocyanate spray, strong solvent aerosols) genuinely does need gloves, goggles, or a respirator. This guide names the H-codes that trigger each, and points to safer picks by category.
