I have used Silver Olas Carpet Tile Flood Cleaning for over 30 years. They are able to clean the carpets even with animals and get every stain out where other companies could not. Because of this I only use Silver Olas Carpet Tile Flood Cleaning. They are a little more expensive but the job that they do makes it so easy and you only need one cleaning a year which in the long run will save you money. The carpets always come out fantastic.
When the carpet technician arrives he vacuums the entire carpet and makes sure there is nothing left on it. Then he pre-treats the stained areas and then proceeds to the shampooing. Every carpet technician that has cleaned my carpet is of good character, whatever they tell you they are very truthful about it. I have been very pleased for 30 years!
