Air Soluble Marker

[jmyhogan]

I use the Collins (purple) "Vanishing Fabric Marker" frequently. If it has not disappeared in a reasonable amount of time I spritz it with a fine spray fo water from the spray bottle. It always turns a dark purple until it dries. When it is dry it is nearly always all gone. If there are little traces left I spritz it lightly again.

I know that different areas have different minerals and chemicals in the water and that can affect stuff like this greatly so extensive testing may be wise. Also, chemicals in or on the fabric can make a big difference as well.
