Doctordon -
Thanks for those links from Rich.
I have also used it on vehicles just like those in the links, and it really does get all the ga-ga out fast, and the bonus of doing some sanitizing along the way is really a good thing also.
On leather, it was mentioned that it removes the sheen from most leathers, and that is so correct. and when you remove that sheen and look at your white towel that is mounted on the big triangular brush, you will be amazed at all the dark residue,( which is not the color of the leather) on the towel!
So I have to assume that this residue is probably conditioners maybe and a lot of dirt that is embedded in the leather, that is now removed.
Believe I read somewhere that really shiny leather, unless it was made and finished shiny is holding dirt and oils, and that gives it the shine.
The steamer carefully used in the leather seams is invaluable in getting out all that dirt, food, coffee, etc., that falls into those cracks and into the seams out. Yes, you can brush it out, but it takes longer perhaps, and the softening effect of the heated steam seems to loosen things up faster and bring them out quicker in my experience..
All the vehicles I do with leather seats and steam look, feel, and smell so much better when done.
I only use Spinneybeck leather conditioner on leather cleaned this way because they are a tannery that sells leather and automotive leather, and they recommend using this on cleaned leather. It has no odor at all, and is very easy to use.
If a Client wants a "leather smell" I will still use Spinneybeck first, and then later, go over them again with something like Zaino Z-10 I think it is, and that gives a nice leather smell to the seats, etc...
Pretty hard to beat a Steamer for inside and outside work, figure on a normal detail or two to pay for it maybe... High end detail will probably buy a couple of them ?
Good luck with your project !
