It has two uses, one as a lubricant for clay and as a simple cleaner - polish.

As a lubricant, it is very good, providing sufficient lubrication... but I would not recommend it since plain soap and water do exactly the same thing. It's not that it doesn't do a good job, but it's not 100% necessary. For example, if resin or pitch falls and you don't have time to use soap, then yes, but if you have a schedule to wash the car, it's not worth washing it, drying it, and then using Rapid detailer.

As a cleaner, it is also very good. Its purpose is not to clean heavy dirt, but because it has lubrication, it is good for removing dust and fingerprints without removing the wax.

It works for windows, paint, but for the interior, except for seats and screens.

Use as a lubricant for clay, very good and nice smell. Similarly, for a final touch after a good wash.
