Review on Chemical Guys SPI_993_16 Nonsense Colorless by Heidi Thompson

I used this on my car's interior/dash. Spray on, leave on for 20-30 seconds, spray a little onto the brush for detail and then gently start brushing the area. Then dry with a microfiber cloth. When it starts to foam, you're kicking up dirt, grease, grime, etc. This is what you need when using this product. Also, there is no smell or smell, which is very nice. Make sure it's cool inside and the dashboard/car isn't too hot. This product gives excellent results when used in the afternoon or when the car is parked in a garage or in a shady area.
