Is there TCE in WD-40

No, WD-40 does not contain trichloroethylene (TCE). The formula for WD-40 is a proprietary blend of ingredients, primarily consisting of aliphatic hydrocarbons, mineral oil, and various additives. TCE has been phased out of many consumer products due to health concerns, and WD-40 has not included it in its formulation. Always refer to the product's safety data sheet for the most accurate and up-to-date information.
