Sorry to dig up a very old thread, but i didn't want to start a new one on the same product. I tried VP heavy duty extraction cleaner for the first time today in a minging Nissan Navara thats used as pool car at an oil refinery. I was extremely impressed with its carpet and fabric cleaning abilities, but what impressed me more was its ability to clean plastics. I did the usual thing of cleaning the plastics down with APC, but as you know sometimes mud is so ingrained it seems to dye them brown. I was going to attack them with some tfr after i did the carpets, but during spraying the carpets with the vp extraction cleaner (1:4 with water - the carpets were disgusting) some went on the plastics so i wiped it off with a microfibre, it brought them up spotlessly! I ended up going over all the stained plastics with it, i just sprayed on and the wiped off - even with tfr i find i have to agitate sometimes! Over the last few weeks i've been trying a few VP products and i am seriously impressed.
