How long do vinyl and acetate dub plates last?

Vinyl dubs last about as long as regular pressed vinyl, and if cared for properly acetates can last just as long. However acetates can wear down quickly if played with too much tracking force, or with a very abrasive stylus (its a good idea to test how abrasive your stylus is by playing the lead out spiral several times. If you notice the surface noise increasing, its best to use a different stylus).
