Carpet cleaner solution recommendations

[Al@n]

Looking for the best carpet cleaner solution to clean a beige carpet to clean some stains of chimney soot, dark ingrained stains on the carpet

Any recommendations?

I have a Henry wash carpet cleaner, will be up to the job or should I also hire a rug doctor instead?

Or should I consider any other alternative carpet washers?
