Engrave or etch using an electric engraving tool or hand engraver. This method leaves a visible, permanent mark.
An acid etching kit is useful for many hard surfaces. Use it to etch or engrave your vehicle registration onto your in-car entertainment, details of make and model and the serial numbers, should be kept in your vehicle logbook, which should not be kept within your car, in case of theft.
Ultraviolet marking (invisible marking) glows clearly under an ultraviolet lamp. The marking is not totally invisible, and therefore should be used on surfaces not readily on view, for example the back, side, or base of a television or video player. Also it should be noted that the mark can fade in daylight and may need renewing.
Ceramic pens have been developed for marking china, glass, and other glazed surfaces.
For heavier items, such as pushchairs, cycles, and lawnmowers use a set of punches and a hammer.
Not all items are suitable for marking, jewellery and antiques, for example where attempting to mark them would damage or de-value the item.
Photographs of each item against a plain background with a ruler next to the item to give an idea of size are very useful. A video film of property in its usual place also proves useful, as your memory at a time of crisis may be unreliable.
