Cheers guys, a mate has a vax so I'll be getting some product and vaxing the gunk out of my seats soon!
tip!!! dont over soak your seats

they will take ages to dry and will make your interior smell rank the next day.
biobrisk: as mentioned above is very good product, its great for spray extraction machines, been using it for years and have made had no complaints from customers. highly recomend it.
