Oh no, another engineer!
Used it on the upholstery of a modereatly soiled mini-van and I am sold! There were a few organic based stains and spots in the car and this stuff (in a pretty decent 3:1 concentration of solution to water) did a very good job. Sprayed on, let sit for 30 seconds or so, scrubbed with a brush, extracted and gone, all of them. Was very pleased with the product.
