$0.65BEST $/OZ

A standard-dilution rinseless wash concentrate (256:1) designed for maintenance washes on lightly soiled vehicles, safe for paint, ceramic coatings, PPF, and wraps.

Key Chemistry

pH Level

4.5

Active Mechanism

surfactant encapsulation with silicone lubrication

Surfactants

2 (nonionic)

Expert Analysis

This concentrate relies on nonionic surfactants to lift and encapsulate light soiling without a follow-up rinse, allowing dirt to be wiped away with a dry towel. Among the disclosed ingredients is a hydroxy-terminated, ethoxylated/propoxylated silicone surfactant (3–<5%), which can contribute both surface conditioning and the slick, low-friction glide associated with rinseless washes. The mildly acidic pH of 4.5 keeps the chemistry gentle on existing waxes, sealants, and coatings.

Key Differentiators

  • Includes a hydroxy-terminated ethoxylated/propoxylated silicone surfactant that can add lubricity and a conditioned, slick finish during wipe-down
  • Very high 256:1 dilution makes the concentrate economical per wash and flexible for both bucket and spray application

Potential Concerns

  • Ingredient disclosure is limited to regulated SDS components, so the cleaning system, encapsulation chemistry, and any added lubricants beyond the disclosed silicone surfactant remain unknown
  • As a rinseless designed for light soiling, it is not intended for heavily contaminated or gritty surfaces, where wiping without a rinse increases marring risk
