No Safety Data Sheet on file.
CarCareTruth has not received a Safety Data Sheet from the manufacturer for this product, so no GHS hazard classification can be cited. The tiers below are cautious defaults — “Beyond SDS” — translated from the product’s ingredient chemistry and how comparable formulations classify, not from a manufacturer hazard classification. Request an SDS from the manufacturer before use.

Beyond SDS: translated from the ingredient chemistry
No GHS eye classification is on file (no SDS published for SKU 10479). Bucket dilution and towel application carry routine splash potential · situational eye protection is appropriate without confirmed chemistry.

Beyond SDS: translated from the ingredient chemistry
No GHS skin classification is on file. The CMIT/MIT preservative pair is a confirmed skin sensitizer at the ingredient level; at the bottle's concentrate strength glove use is appropriate during decanting and dilution. At the in-bucket working dilution (~1:256) sensitization risk is reduced but not eliminated for repeat-exposure users.

Beyond SDS: translated from the ingredient chemistry
The CA Right-to-Know sheet confirms methylchloroisothiazolinone (CMIT) and methylisothiazolinone (MIT) · both established respiratory asthmagens at the ingredient level. The asthmagen rule (rubric §PPE tier guidance) sets lungs at recommended even without a confirmed SDS §2 classification. Decant, dilute, and pour the concentrate in well-ventilated space; the diluted bucket solution carries lower inhalation risk.

Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

Last reviewed July 9, 2026
TL;DR Concentrated bucket-method wash · one ounce per two gallons, about 35 buckets per bottle. The SKU is new and the review base is still modest, so dark-paint lubrication evidence is thin. Health is held at 5.0 because Griot's hasn't published a Safety Data Sheet.
Dilute one ounce into two gallons of water, dip a microfiber, wring lightly, wipe a panel, then dry with a second clean towel. Owners report clean wipe-off on light dust and fingerprints. Long-term scratch-safety evidence on dark paint isn't available yet · the SKU is new and forum coverage is sparse.
Best fit is the bucket-and-towel user · apartment dwellers, water-restricted areas, garage washers on light soil. Skip it if you want a ready-to-use pump spray, if the car carries visible road film between washes, or if you want a long forum record before trusting it on dark paint.
No Safety Data Sheet has been located for SKU 10479 as of May 2026 · only the Wax variant has one. Health is held at 5.0 because Griot's hasn't published an SDS, not because the chemistry is known to be unsafe. The California Right-to-Know sheet confirms two preservative asthmagens · methylchloroisothiazolinone and methylisothiazolinone · which sets lungs PPE to recommended; gloves during decanting are sensible. The bucket method eliminates the 60-100 gallons of hose water a conventional wash uses.
Plain Rinseless Wash (SKU 10479, this page) is wash chemistry only · concentrated wash agents in a water carrier, no protection topper. Rinseless Wash & Wax (SKU 10818) is the same wash chemistry with an added wax topper that leaves a short-term hydrophobic film. Buy plain Rinseless Wash if you wax separately or use a ceramic coating; buy the Wax variant if you want the wash and a quick protection refresh in one step.
Griot's instructions are 1 ounce of concentrate per 2 gallons of water · about a 1:256 ratio. A 35 oz bottle yields roughly 35 wash buckets at the recommended dilution. The concentrate is the form Griot's actively sells; the gallon variant is the same concentrate in a larger bottle, not a ready-to-use solution.
Griot's markets the product as compatible with ceramic coatings, and the formula contains no abrasives or stripping agents. No independent third-party coating manufacturer has formally endorsed the product. Bucket-method dilution at 1:256 produces a mild working solution unlikely to degrade a cured ceramic coating in normal use.
Griot's has not published a Safety Data Sheet for SKU 10479 · the brand site links to the wax variant's SDS but not to one for the plain Rinseless Wash. Without a verified GHS SDS, mixture-level hazard classifications cannot be confirmed. Per CarCareTruth's no-SDS rule, health is set to 5.0 with a 'NO SDS' label until an SDS is obtained. The CA Right-to-Know ingredient list confirms two preservative asthmagens (CMIT and MIT), which would carry forward as a deduction once an SDS classification is on file.
The product listing does not show a Prop 65 warning, and the CA Right-to-Know ingredient list for SKU 10479 contains no Prop 65·listed substances at disclosed concentrations. The current 'no Prop 65' determination is based on the Right-to-Know sheet rather than a verified SDS Section 15.
