TL;DR Reliable weekly-wash shampoo that cleans road film and brake dust without stripping wax, sealants, or ceramic coatings, and the broad owner consensus backs that up. It carries a California Prop 65 warning (a Prop 65-listed carcinogen, from the SDS).
California Gold High Performance Car Wash lifts road film, brake dust, and general grime in a two-bucket or foam-cannon wash. Dilute roughly 1 oz per gallon · the formula lathers and cleans reliably on regularly maintained cars; heavily contaminated vehicles may need a pre-rinse. Foam volume is adequate but suds collapse quickly, an owner observation. The standout community note is surface safety: no documented wax or coating stripping at normal wash concentration, consistent with the near-neutral concentrate pH confirmed in SDS Section 9.
Best for weekly-wash owners who don't want to disturb existing protection · wax, sealant, or ceramic coating. Foam-cannon compatible out of the box. Skip it if you're stripping protection before a fresh wax or coating application; a dedicated strip shampoo is the right tool for that. Skip it also if foam volume is a priority · there are higher-lather alternatives at similar prices.
The SDS classifies this product as not hazardous · no GHS H-codes, no signal word, and Section 8 states no protective equipment is required under normal conditions. A California Prop 65 warning applies: sulfuric acid (a carcinogen) is in SDS Section 15. The entire working solution runs to driveway runoff and storm drain; one of the named cleaning ingredients has documented aquatic toxicity in its ingredient chemistry file, reflected in the environment score. No biodegradability credit applies · SDS Section 12 reports no data.
The SDS confirms a near-neutral pH of 6.0·6.5 at concentrate, and the product label explicitly states it cleans without stripping wax, sealants, or ceramic coatings. Community feedback from owners of ceramic-coated cars is consistent with this claim.
Yes, the product is marketed as foam cannon and foam gun compatible. Owners confirm it produces adequate foam in foam guns; volume is moderate rather than exceptional compared to dedicated high-foam products.
Yes. A California Prop 65 warning applies · sulfuric acid (a carcinogen) is listed in SDS Section 15. This warning is also shown on the product listing.
The label recommends approximately 1 oz per gallon of water (roughly 1:128). At this dilution, the near-neutral concentrate pH is further diluted toward neutral.
The label says 'eco-friendly' but SDS Section 12 reports no biodegradability data for the product mixture. No biodegradability credit applies · SDS Section 12 has no information available.

What's Actually in Your Car Shampoo: An Ingredient Guide
A car shampoo is mostly water, a small mix of soaps called surfactants, and a few helpers (chelator, pH buffer, preservative, fragrance, sometimes a wax or silicone). The surfactant mix is what makes one bottle coating-safe and another a wax-stripper.
