I have a 2003 Honda Accord and I have never cleaned the carpet or the seats. I had to go over them twice. The first time I mixed 4:1 and then went back over them at 10:1. It even got coffee stains out. My wife is really happy.

Pros-very versatile product. Can be used on all vinyl, plastic, rubber.
Can be mixed to your desired strength.
Smells nice and fresh!
Cons-Nothing
I use this product 10:1 for interiors
7:1 for wheel wells and tires. Works great and you can see the brown melt away.

I dillute this 10:1 and wow cleaned my leather seats very good.
