One of the most frequently asked questions we receive is how to remove old red stains from carpet. In fact I just had an emergency call asking that question. Rather than write a lengthy article I searched online and came across this story. A few caveats are in order though: 1) Make sure the towel is soaking wet, and 2) Use the lowest setting on the iron that will produce steam. Check the stain every 30 seconds to 1 minute, and be sure to rotate the towel to keep it wet!
