Resolve carpet cleaner spray or granules work well. Apply, then scrub into spots. Let set, then vacuum.
What are the spots from?
The BEST stain remover is called: Folex Carpet spot remover. We had to order it online, but it really does work very well! It is the best and was recommended by a fellow DIY hometalk person. Hope this helps, Annie
Thanks Annie...I've been looking for something that takes black markings off
carpet (from shoes). I'll give this a try Resolve and other products have not
been successful so far.
I am amazed at how well this works (even took old mascara stains out of my daughter's rug): https://amzn.to/2FCmMus
