The DYKEM 91938 is a detergent-removable layout and marking fluid marker designed for use on metal, plastic, and other hard surfaces common in industrial and trade environments. The medium tip delivers controlled, visible blue lines for scribing, layout work, part marking, and inspection tasks. The SUDZ-OFF formulation washes off with standard detergent and water, eliminating the need for solvents during cleanup. Licensed tradespeople and fabrication shops use this marker where temporary, cleanable markings are required without leaving a permanent residue.
This marker is suited for job sites, fabrication shops, machine shops, and maintenance environments where parts need to be marked before cutting, drilling, or assembly. The blue color provides strong contrast on bare metal, primed surfaces, and light-colored materials. It is sold individually and is compatible with standard workflow processes that require post-process cleanup without chemical solvents.
Designed as a temporary marking solution for use on metal, plastic, and other hard industrial surfaces where detergent-washable markings are required.
No installation is required for this marker. Store with the cap secured to prevent tip dry-out. For best results, ensure the surface is free of heavy oils or grease before marking. Dispose of used markers in accordance with local waste regulations.
