The DYKEM 91371 is a detergent-removable layout marker designed for use on metal, glass, and other hard surfaces in industrial and trade environments. It lays down a bright green mark that holds up during fabrication, machining, and assembly work, then washes off cleanly with soap and water or standard detergent. The medium tip delivers a consistent line width suitable for scribing reference lines, marking cut points, or annotating workpieces. This marker is used by machinists, pipefitters, fabricators, and maintenance technicians who need a mark that disappears at cleanup without solvents or abrasive prep.
The DYKEM 91371 fits into workflows where temporary, high-visibility marking is required on shop floors, pipe spools, structural steel, or production assemblies. The detergent-removable formula makes it practical for applications where permanent ink would contaminate a surface finish or complicate final inspection. It is well suited to metal fabrication shops, HVAC duct work staging areas, plumbing rough-in, and light industrial maintenance environments where clean removal is a requirement after the work is done.
Designed as a general-purpose detergent-removable layout marker for use on metal, glass, and hard non-porous surfaces in industrial and trade applications.
No installation is required for this marker. Allow marks to dry fully before handling workpieces to avoid smearing. Remove marks with standard detergent and water prior to final surface finishing or coating. Store with cap secured to prevent tip drying.
