TL;DR Dilutes 10:1 for general interior and exterior cleaning, down to 4:1 for engine bays and stuck-on grease · community confirms it cuts common soils effectively and is safe on paint, rubber, and plastic trim at proper dilution. EPA Safer Choice certified with zero VOC; carries a Prop 65 warning on the label.
Mix it 10:1 in a spray bottle for general interior and door-jamb work, 4:1 for engine bays and stuck grease, and 30:1 for headliners and light dust film · one gallon yields enough working solution to handle a full detailing season for most home owners. Spray, let it dwell 15·30 seconds on soiled surfaces, agitate with a brush or microfiber, and wipe or rinse off. Community broadly confirms effective single-pass cleaning on common interior soils at 10:1; heavier grease takes the 4:1 ratio and a second pass. The dilution economy is the defining advantage · the per-use cost undercuts most dedicated detailing concentrates significantly.
Home owners and car enthusiasts looking for a do-everything concentrate at a budget price point will find this covers nearly the full all-purpose-cleaner use catalog · interior surfaces, exterior detail spots, engine bays, wheels, and pre-wash. The EPA Safer Choice formula is a genuine differentiator for buyers who want confirmed ingredient safety rather than marketing claims. Buyers who need maximum alkaline grease-cutting power on heavily soiled engine bays or commercial vehicles may find a dedicated professional detailing concentrate more aggressive at equal dilution; they trade away the safety profile for cleaning muscle.
The SDS classifies this product as not hazardous under the 2012 OSHA Hazard Communication Standard · no GHS signal word, no H-codes, and no pictograms required. The concentrate pH is approximately 9.0, dropping to roughly 8.1·8.5 at the recommended 10:1 working dilution · mildly alkaline and well below any GHS health classification threshold at use concentration. VOC content is 0 g/L per SCAQMD Method 304-91, and the formula carries EPA Safer Choice certification confirming every ingredient meets EPA human health and environmental safety criteria. The product carries a California Prop 65 warning on its the product listing. The formula is biodegradable and drain-destined; the surfactant-based chemistry breaks down readily and carries no aquatic toxicity classification at mixture level in the SDS.
At the recommended working dilution (10:1 for general cleaning), the pH drops to approximately 8.1·8.5 · mildly alkaline. Community evidence broadly confirms it is safe on paint and ceramic coatings at this dilution, though some detailers report caution at stronger dilutions on sealed paint. Always test on an inconspicuous area first on freshly-coated surfaces.
Simple Green's dilution chart recommends approximately 10:1 (water:concentrate) for general interior and exterior cleaning, 4:1 for heavy grease such as engine bay work, and 30:1 for light dust and interior film. Start at 10:1 for typical detailing tasks.
No. The SDS §3 ingredient list contains no ammonia, bleach, or chlorine compounds. The formula is based on surfactants, a chelating agent, and sodium bicarbonate · making it compatible with tinted windows and automotive finishes.
Yes. The Industrial Cleaner & Degreaser carries EPA Safer Choice recognition, which requires independent review of all ingredients for human health and environmental safety. The VOC content is 0 g/L (SCAQMD 304-91 method), and the product is not classified as hazardous under OSHA HCS 2012.
Yes. The manufacturer's dilution chart covers pressure washer and equipment use. For foam cannon or foam gun application, dilute appropriately per the task · typically 10:1 to 30:1 depending on soil level.
