What substance primarily makes up Sonic Suds?

Sonic Suds is primarily made up of foaming soap, which is designed to effectively cleanse surfaces without scratching or damaging them. The foaming action helps to lift dirt, grime, and other contaminants off the vehicle's surface, ensuring a thorough wash. This type of soap is formulated to create a rich foam that can cling to the surfaces being cleaned, allowing the cleaning agents to work more effectively. The other substances listed, while they may be associated with automotive care in other contexts, do not represent the main composition of Sonic Suds, making foaming soap the most appropriate choice.
