I spilled bright red nail polish on white, wool carpet in my rental apartment. Stain busters came by straightaway (even though he was fully booked that day. He still dropped by to have a look and do emergency job for me). He came back few days later and finished the job for me. All the stains gone now! I am really happy with the service and grateful for his caring attitude. Highly recommended for anyone who has issues with their stained carpet.
