ok, I don't toss my equipment around or mistreat it at all, but my wracking cane, and bottling wand all have hairline cracks running lengthwise down them and I've only had them for about a year at most..... is this common with the plastic racking equipment? should I just trash them or are they still usuable? I keep them soaking in oxyclean most of the time so they're clean as a whistle, but I'd hate to have to rebuy racking equipment every 6-8 months if this is a common thing.
