— these markers don’t wash off with water or rain once dry, so they’re handy for labeling warehouse and delivery boxes, outdoor signs, garden pots, cables, lab test tubes, and freezer containers. Most are alcohol- or oil-based, less often pigment- or acrylic-based, which is why they bond quickly to plastic, metal, glass, and wood and last noticeably longer than regular water-based markers. They feel like “permanent” markers, but here’s the nuance: water resistance isn’t the same as solvent resistance—marks can usually be removed with alcohol, acetone, or a dedicated cleaner. The trade-off for durability can be some odor and bleed-through on thin paper, so for documents use heavier sheets and air out the room; on slick surfaces, a quick degrease before writing helps.
