I like your process Takumi587, I do things a bit different...something like this:
- Remove floor mats
- Vacuum the entire interior
- With hot water and some Meg's
APC (dilution varies on how bad the condition of the interior) and a MF towel I do a complete interior wipe down. For vents or other hard to reach areas I use a Swissol Brush.
- For the carpet I use a mixture of Meg's
APC and my little Green machine (I use this for the time being till I get my Mytee)
- I dress all plastic/vinyl with either Meg's #40 or 303 or Optimum Plus Protection....all depends on what appearance the customer wants.
- For leather I use Lexol PH Cleaner with yet another bucket of water. I use a foam applicator to agitate the leather. Then with another MF towel I wipe off what's left of the Lexol PH cleaner.
- Then I follow the leather up with Lexol Leather Conditioner, I set up my 1000W and 500W lights to worm up the leather. Once the leather is nice and toasty I apply the Leaxol Leather Conditioner by hand. I apply the conditioner to all the leather let it sit for a bit and then wipe off what ever is left over. There is not much to remove though as the leather just sucks up the conditioner.
I've been looking into a steamer for quite some time now but I figure first hot water extractor (Mytee) and then the steamer. The extractor will shed some time from the interior.
Well that's just my process and it's been working great for me so far.
