Steam Cleaning Grout - 2013:
"Steam eats your grout! That's how they clean grout. Clean your grout 3-4 times with steam and see what happens...Signed Greg M."
Yesterday I received an email from Thumbtack.com stating that I had a review from Greg M. Thumbtack.com is a free referral service where clients can search for all types of service professionals. If you have ever used Service Magic to find a plumber, gardner, etc. it is similar in how they operate. Thumbtack will send your request to all of their vendors and if the vendor wants to they can put in a bid for your tile and grout cleaning for a small fee of around $4.00. The review we receive was quite negative and here is what Greg M. said:
The first thing I did was to look into my data base and I discovered that I DID NOT have Greg M. for a client or referral source. We have NEVER done business with a Greg M.
Secondly, we DO NOT use steam to clean grout we use hot water under pressure. Stanley Steemer does not use steam to clean carpets they also use hot water under pressure. If you place a pot of water on the stove it will convert to steam at 212 degrees farenhiet. If you place water under pressure it will convert to steam at 252 degrees. Our typical water temperature is about 220 degrees. Grout is nothing more than colored concrete, and if you do some research you will discover that concrete remains unaffected by temperature until it reaches 572 degrees. The measurable change deals more with color than it does with structural integrity. Ask any fireman and they will tell you that it is common for a residential fire to exceed 1,000 degrees farenhiet. If you have ever looked at the aftermath of a fire you will notice that the only thing still in tact is the concrete. If Greg M's claim was true then the manufactures of the Steam Shark would be facing mega lawsuits and the product would have been pulled off the shelf. One way you can tell if Greg M. is telling the truth about steam cleaning grout is to take your steam iron and blast away at your grout 3-4 times on high power and see what happens - NOTHING.
Thirdly, concrete has a psi rating of 4,000 (PSI stands for pounds per square inch) and we typically clean grout and tile at a psi rating of 1,400 to 1,800. Concrete has been around since the Romans and some of their structures are still standing 2,000 years later.
I personally believe that Greg M. is one of those "uneducated," "unscrupulous," "uniformed" service companies that we have warned you about. I hope this information has been helpful to you.
