I have a little pen item from LQS that you can refill the water part much like the cartridge ink pens I used in HS. It works well for very specific spot cleaning with water. BTY I quit using the markers when I had a customer give me a quilt that the green would not wash out until I used Grandma's Stain Stick in the first wash and then OxyClean in 2nd wash--I found out later that she had used starch in the fabric and that may have made the difference. But I'm not going to try it again.
