On hard plastic and laminate, generally yes; on painted surfaces, coated metal, leatherette, mesh and screens, alcohol is the thing most likely to leave a lasting mark.
Alcohol evaporates fast and leaves nothing behind, which is why it suits keyboards, hard plastic armrest caps and a laminate desktop. The risk is not the dirt it removes but the finish it can take with it.
Where it is usually fine. Hard, uncoated plastic — keycaps, the plastic shell of a mouse, armrest caps — and laminate desktops tolerate an alcohol wipe well. On laminate, wipe the surface rather than the edges, where moisture can work into the core; cleaning a laminate desktop covers that.
Where to hold back. Painted and powder-coated parts, the printed legends on a desk’s control handset, leatherette and soft-touch plastics react to repeated alcohol — fading, a sticky surface, or a button label worn off for good. Leather and regenerated-leather desk pads dry out; caring for a leather desk pad gives the gentler routine. On tensioned chair mesh, alcohol does nothing a damp cloth would not, and can stiffen some fabrics.
Screens are their own case. Many monitor makers advise against alcohol or ammonia cleaners on the panel’s anti-glare coating; check the manual, and see cleaning a monitor screen safely.
The habit worth keeping is to test on a hidden area first and to use alcohol where it has a reason — a shared keyboard, a handset several people touch — rather than as a general cleaner. For everything else, a barely damp cloth with a drop of mild soap is gentler and sufficient; cleaning a mesh office chair and cleaning a keyboard go through the specific cases.
