as for me I prefer using carpet cleaning services instead of cleaning by myself

I recently cleaned a long-pile carpet. I used the following composition: for 1 liter of warm water, I added 2 tablespoons of soda, 1 tablespoon of washing powder and 1 tablespoon of 9% table vinegar. First you need to decide what kind of spots. When the masters work, they first determine what the contamination is from and only then start working. There are impurities such as coffee, wine, etc. Which in no case should not be cleaned with an alkaline agent, it can not only not go away, but on the contrary to gain a foothold and it will either be difficult to clean even experienced craftsmen, and perhaps it will not go away. I wasn't able to clean my carpet well so I turned to the professionals https://www.rugcleaningnyc.net/ and I didn't regret my choice at all.
