Mardie,
Yes, this is mostly a hot water extraction forum. Though many here have have used and still utilize other methods as well. So, most of the veterans' opinions here (Brian excluded

) are a choice they made after trying quite a few methods. In other words: It is, right or wrong, what we deemed through experience to be the best method.
The issue is that you come in the foot steps of companies like Chem Who that have used and still do, for years, spread misinformation about steam cleaning.
Are there unethical steam cleaners? Yep! But there are a lot of unethical cleaners using any cleaning methods.
1) Your web site, however, goes in the great tradition of Chem Who. See "carpet cleaning
facts and misconceptions" :
http://www.naturalcleaningsystems.ca/cleanfacts.htm
Those are not facts and it is you who is actively engaged in spreading (creating? enforcing, misleading your potential clients?) the misconceptions.
2) Your name "natural Cleaning Systems" suggests that all your products are natural, which I personally doubt. No MSDS, no direct claims about the products being all Natural. However, though you may be legally in the clear, through fine print wizardry, ethically (unless you use 100% natural products) you are in muddy waters indeed. In clearer words- you are misleading your potential clients.
Lets see the chemical facts about your "Natural Cleaning."
Unless, of course, what you really mean is that you were just born for this business as cleaning just comes naturally to you.
Any good lawyer, will help you word it just right. If not, see Chem Who literature- It's a classic :shock:
