Hello! I need some help! Does anyone know marking pen that is water soluble? I want to wash off marker in a cleaning machine using only hot water. I tried many different type of water soluble marking pen, but it did not come off easily.

Years ago, we used a specialty-marking pen like you describe. The pen has: * �Fluxmarker 6135 W BELMONT CHICAGO IL 60634 / 1-312-889-8323 Illinois / All other states Toll Free 1-800-621-0080 bla bla bla � marked on the barrel. A quick search with Google produced �EMF 800-621-0080� and little else. EMF; at one time [maybe still] was [is] an electronic manufacturing tool / MRO distributor. Maybe try electronic manufacturing stuff distributors, like Wassco, Techni-Tool, HMC, Marshall, Contact East, Jensen, etc * Problem of limited contrast between the pen and the solder mask on the board, orange was better than blue, but it still �

They may have improved this product, subsequent to our experiences.

did you try DRY ERASE markers? ( the ones used for white boards). It's just a thought, I'm not sure if that will work. Doesn't hurt to try.

Thanks! dry erase does not come off easily with water. I have to use brush to remove marks. Thanks for your input anyway!

Believe it or not, we use kid's markers like Crayola. Some colors come off more readily than others so you may have to experiment. We use it on aluminum so it may not be just right for you but it's an inexpensive test. Kind of made us happy when marker cost went from $20+ to a ten pack for $3. And we can draw pictures of management with the colors that don't work...
