What is an ASTM test?

ASTM International (ASTM), originally known as the American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. A standard test method defines the way a test is performed and is developed in conjunction with a specific industry membership, so industry members agree on a way a product is to be tested. Therefore, it brings fairness and agreement across the scientific community when one product is tested against another.

All WD-40 Specialist products have undergone rigorous ASTM testing by independent laboratories and have been proven superior in key product performance areas versus the competition. For WD-40 Specialist test results, visit our products pages.

What is VOC and why is it important?

VOCs (Volatile Organic Compounds) are defined as material in formulation that have high levels of vaporization. This means they vaporize in the atmosphere quickly.

The United States Environmental Protection Agency, as well as The California Air Resource Board (CARB), The Ozone Transport Commission (OTC), and the Lake Michigan Air Directors Consortium (LADCO), regulate the amount of VOC in consumer products. In an effort to reduce the amount of "greenhouse" gasses in the atmosphere, the federal government has limited the amount of highly volatile material manufacturers may use in their formulations. The standard allowable amount is different for each product category (i.e., laundry products, floor cleaners, automobile gasoline, lubricating materials, and many others).

All WD-40 Specialist formulas are 50-State VOC compliant and can be sold in all 50 states, and have been formulated to meet the requirements of CARB, The OTC and LADCO. For more information on VOC Compliance, visit EPA.gov

What is the difference between a solvent-based degreaser and a water-based degreaser?

Solvent-based degreasers typically have stronger cleaning agents and are recommended for heavier jobs. Water-based degreasers typically foam up, but are less effective. However, WD-40 Specialist Industrial-Strength Degreaser (solvent-based formula) has proprietary PowerSolve Technology which unlike other solvent degreasers is safe on most surfaces and won't harm skin.

When should I use a Spray & Stay Gel Lubricant?

Use WD-40 Specialist Spray & Stay Gel Lubricant when you need a long-lasting lubricant that stays in place. This unique thick-gel formula won't run, drip or make a mess. It's safe on multiple surfaces including metal, plastic and rubber and withstands temperature ranges from -100F to 500F.
