From the manufacturer’s Safety Data Sheet, Section 8

From the manufacturer’s Safety Data Sheet, Section 8
“H335 (respiratory irritation) is listed at concentrate strength from sodium metasilicate STOT SE 3. At 5:1 working dilution, metasilicate drops to 0.1-0.36% · below the GHS mixture threshold for H335 classification. SDS §8.3 specifies general or local exhaust ventilation for occupational use. For typical home-detailing spray sessions, no respiratory protection is needed outdoors or in a well-ventilated garage.”

This product ranks #2 of 12 in All-Purpose Cleaner (APC).
Last reviewed June 9, 2026
TL;DR One of the most trusted all-purpose cleaners in the car-care community. Optimum Power Clean covers the full APC task list, from bug and tar removal at full strength to gentle interior vinyl cleaning at 5:1, with a clean safety profile at working dilution and no Prop 65 warning. A solid pick for owners who want one bottle for everything.
Power Clean is an alkaline concentrate built on an ethoxylated C9-11 nonionic surfactant, with disodium metasilicate as the alkaline builder (pH 11.5 at product strength) and a glycol-ether co-solvent for grease cutting. Use 3:1 for wheels and heavy cleaning, 5:1 for interior surfaces and painted panels, up to 10:1 for headliners. Bug and tar removal at full strength or 3:1 is its standout trait, with Autogeek threads reporting it replaces a dedicated bug remover on most vehicles.
Buy it if you want a community-vetted, versatile APC that covers exterior heavy cleaning and interior work through dilution, with no Prop 65 chemicals and low VOC. Skip it if you need best-in-class per-use economics (a gallon competitor wins at high volume) or a pH-neutral formula for the most sensitive surfaces.
At product strength the SDS classifies Power Clean as DANGER, GHS05, with H314 (skin corrosion) and H318 (serious eye damage) from the metasilicate and surfactant package. At the 5:1 interior dilution this product is scored at, the metasilicate drops below the corrosion threshold, H314 no longer persists, and classification steps down to WARNING with H315/H319. Gloves and safety glasses suit working-solution spray use. The C9-11 surfactant is toxic to aquatic invertebrates at mg/L levels, so rinse and wash water should reach wastewater treatment, not storm drains.
Optimum recommends 5:1 (5 parts water to 1 part Power Clean) for leather, vinyl, and dashboard surfaces. For wheels and tires, use full strength or 3:1. For painted exterior surfaces, 3:1. For lighter maintenance cleaning, dilute up to 10:1. The product is alkaline at product strength (pH 11.5) · always use the correct dilution for the surface to avoid potential chemistry incompatibility with wax or sealant coatings.
At 5:1 or higher dilution, Power Clean is broadly reported safe on ceramic-coated surfaces in the r/AutoDetailing and Autogeek communities. The alkaline pH at product strength (11.5) could theoretically challenge some coatings over repeated heavy use · use 5:1 or weaker and avoid extended dwell time on coated paint. Multiple Autogeek threads confirm safe use at working dilution for routine maintenance cleaning on coated vehicles.
Bug and tar removal is one of Power Clean's most documented strengths in the enthusiast community. Apply at 3:1 or full strength to affected areas, allow a 30·60 second dwell, agitate with a soft brush or sponge, and rinse. Multiple forum threads (Autogeek, r/AutoDetailing) confirm effective bug/tar removal without requiring a separate dedicated remover product.
Both are formulated by Optimum Polymer Technologies · the Opti-Coat branded version is the same chemistry sold through detailing specialty retailers (Opti-Coat, The Rag Company). The 2023 SDS covers both products under the Optimum Polymer Technologies entity. Choose based on retailer preference and availability.

How to Detail Your Car at Home: The Complete Beginner's Guide
You do not need a pro, a shop, or a garage full of gear to make your car look great. Detailing is cleaning in the right order with the right product type for each surface. Work the exterior dirtiest-first, then dry-to-wet, then the interior top-down, and let each product dwell and lift the dirt instead of grinding it in. This guide walks the whole job start to finish for a first-timer and links to the deep guide and scored picks at every step. Start small and build from there.

Detailing PPE: When You Actually Need Gloves or a Respirator
Most weekend car care needs zero PPE. A small list of chemistries (fluoride wheel acids, isocyanate spray, strong solvent aerosols) genuinely does need gloves, goggles, or a respirator. This guide names the H-codes that trigger each, and points to safer picks by category.
