Health score is for adult use as intended. No manufacturer SDS is on file, so it is translated from the ingredient chemistry. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.
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.

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.

TL;DR Community confirms four to six weeks of real protection on a daily driver · not the label's six months · and no real correction since the formula contains no abrasive. No Safety Data Sheet is on file for this product.
Klasse All-In-One is an acrylic-based cleaner sealant applied by hand pad and wiped off without any drying time. It removes surface buildup and leaves a deep, glossy finish that consistently draws praise from long-term users. Application is genuinely forgiving · no high-spot issues reported, first-timers get clean results. Protection is the weak point: the label claims six months or more; forum users and long-term owners consistently report four to six weeks on a weekly-washed daily driver.
Best for drivers who want effortless maintenance and standout gloss on paint already in good shape. Skip it if you have a ceramic coating (incompatible with this acrylic chemistry), if you need any swirl correction (no abrasive system), or if you need more than six weeks of protection between applications.
No Safety Data Sheet is publicly available after exhaustive search of the manufacturer's website, SDS repositories, and the product listing · chemistry cannot be assessed. The health score of 5.0 reflects the absence of SDS data, not a confirmed hazard. Based on the exposure profile of a liquid paste applied by hand pad, situational eye, skin, and enclosed-space precautions apply. Klasse is a leave-on product · not rinsed into drains · and the manufacturer's claim of no silicone chemistry suggests lower aquatic-toxicity risk, though this cannot be confirmed without an SDS.
CarCareTruth scores Klasse All-In-One Polish and Sealant at 5.6 out of 10 on the composite CCT score, with a health sub-score of 5.0/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: No SDS on file. From the product listing description and feature bullets (ASIN B0002LBKEW, accessed 2026-05-26): 'acrylic formula' (protection chemistry); 'Contains no abrasives or silicones'; 'not a wax, silicone, or polymer.' Acrylic-based chemistry confirmed by multiple sources. No concentrations available. 'Imported from Germany' per label.
