Prices may varyAbout this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. 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.
GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

From the manufacturer’s Safety Data Sheet, Section 8
“H319 (serious eye irritation Cat 2A) is classified at the mixture level in SDS §2. Pump-spray application generates fine mist at close range; eye protection is the chemistry-based call from H319.”

U.S. regulatory standard
29 CFR 1910.133(a)(1)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”

From the manufacturer’s Safety Data Sheet, Section 8
“No H315 (skin irritation) at the mixture level in SDS §2. IPA is present at 25-50% but the mixture is not classified for skin irritation. Situational tier applies for prolonged or repeated contact per SDS §2 guidance.”

From the manufacturer’s Safety Data Sheet, Section 8
“H336 (drowsiness/dizziness, Cat 3 narcotic) is classified in SDS §2. IPA vapor accumulation during a multi-panel prep session in a poorly ventilated garage is the chemistry basis; this is not SDS boilerplate.”

TL;DR Strips polish oils and silicone residue from corrected paint in a single wipe pass, with community confirmation that coatings bond cleanly after this prep step. The DANGER label is a physical fire hazard from flammability, not a health-severity rating; the health-relevant concerns are eye irritation and IPA narcotic vapors in enclosed spaces.
Koch-Chemie Pps is a ready-to-use prep spray that removes residual polishing oils, wax, and silicone contamination before ceramic or spray-coating application. Spray onto the panel or a microfiber wipe and work one panel at a time; flash-off is moderate, consistent with the IPA concentration plus the slower-evaporating glycol-ether co-solvent. Buyers confirm it outperforms a straight IPA-water dilution on silicone residue, and those using it before coatings report no fisheyes or bonding failures. Highly rated on Amazon, Amazon's Choice in the category.
Best for detailers applying ceramic or spray coatings after paint correction who want purpose-built prep chemistry over a DIY IPA dilution. Skip it for basic wax prep where the price premium over diluted 91% IPA is not justified by the application.
The DANGER signal word comes from H225 (highly flammable, flash point 21 degrees Celsius), a physical hazard. H319 (serious eye irritation, Cat 2A) is classified at the mixture level and drives eyes: recommended for pump-spray use. H315 is absent at the mixture level, so skin PPE is situational for prolonged contact only. H336 (narcotic vapors) is the basis for lungs: situational in enclosed garages. The combined VOC load is estimated at roughly 364 grams per liter, placing it in the notable atmospheric deduction bracket; the product evaporates rather than reaching drains.
Ready to use, applied undiluted. The SDS is written for the as-sold product and the label gives no dilution instruction. Spray directly onto the panel or onto a microfiber towel and wipe.
Yes, that is the intended use case. Multiple buyers confirm they use it as the final prep step before ceramic and spray-coating application, with no bonding failures or fisheyes reported in the community.
The formula includes a glycol-ether co-solvent (in addition to isopropyl alcohol) that helps lift oily and silicone-based residue that IPA alone may not fully remove. Buyers switching from DIY blends report consistent improvement in wipe-down results.
No. SDS Section 15 explicitly states this product contains no listed Prop 65 substances, and no warning label appears on the bottle.
The DANGER rating comes from H225 (highly flammable liquid and vapor) because the flash point is 21 degrees Celsius (70 degrees Fahrenheit). That is a physical fire hazard, not a health hazard. The health-relevant codes are H319 (eye irritation) and H336 (narcotic vapors in enclosed spaces), which are WARNING-tier concerns.
