Jennifer Williams wrote an entertaining story for the Wall Street Journal about how few people are privy to the actual formula for WD-40.
"The handwritten formula is kept in a lockbox at an undisclosed Bank of America location in San Diego. It's only left a bank vault three times in the past 30 years."
"The notebook in the vault — which holds not only the 40th attempt at a formula, resulting in the product's name, but also the 39 failed attempts to get it right — is the only version that has the full makeup of the original formula, which accounted for nearly 80% of WD-40's revenue as of August 2025."
