U-Mark EZ OFF Wet Erase Industrial Marker lays down a bold, high-contrast mark on metal and glass that wipes away with a damp cloth — no solvent, no scrubbing, no halo left behind. It is the marker for in-process identification on parts that must leave the line clean.
Important distinction: EZ OFF is a water-soluble ink marker, not a paint marker. If you need a removable mark that survives more handling and comes off in a water bath before priming or painting, use the U-Mark WASHOFF instead.
Made in Belleville, Illinois, USA. Sold as a 12-count box (1 dozen) in four colors.

Storage & Handling
- Shake well, prime the tip on scrap, and re-cap immediately after marking.
- Store horizontally in a cool dry place out of direct sunlight.
- Validate removal on a sample part before rolling into production — surface finish and dwell time affect results.
- Refer to the U-Mark SDS for full handling guidance. Keep out of reach of children.
Frequently Asked Questions
Will rain or condensation remove the mark?
Yes — it is water soluble by design. For an in-process mark that must survive damp handling and only lift in a wash bath, use the U-Mark WASHOFF or the Munhwa SM Steel Marker.
Does it work on oily metal?
Yes. It is formulated to mark on wet and oily metal in assembly, stamping and fabrication.
Is it safe for indoor use?
It is xylene free and toluene free. Use with normal ventilation and refer to the SDS.
