"An array of aqueous solutions are used to remove dirt. We use an enzymatic solution and another aqueous solution with a more effective ionic strength to clean. While in more sensitive areas we use a breakthrough technology of a silicon polymer emulsion. It's an oil and water mixture. The 10% water in this solution is the effective cleaning agent. The silicone portion prevents the water from penetrating the paint surface. A lot of research went into finding this very elegant solution."
