I read somewhere someone saying they would get their dirty interior steam cleaned. Can this be done? With everything in place? Where? How much?

I have always gone up to Coles or similar and hired their Britex unit with the Upolstery wand for 24 hours. Cost s about $50 including the chemicals. Works a treat. I did 3 cars one day and pulled about 5 kilos or muck out of the carpets and seats. The interiors didnt even look that grubby at the start. Looked like new afterwards.

I remember seeing those when i was a kid, but haven't noticed them for ages. I'll look into it, but if anyone knows where they can definitely be found that would be helpful, as i live a long way from these places.
