The proprietary GR8™ springs on IronMind grippers are made from natural finish steel, and they will oxidize in a humid environment if left to their own devices—and this is cosmetic, not dysfunctional: it will affect the appearance, but not the performance of your gripper. On the other hand, it’s pretty simple to keep the springs on your IronMind gripper shiny and bright, even in challenging climates.
First, remove any oxidation with a light polishing cream to restore the spring to its original appearance. Then block moisture from the spring by wiping it down occasionally with anything from light oil, like WD-40, to car wax. If you prefer a durable protectant that also has a dry finish (unlike oil), you might want to give the Sentry Tuf-Cloth a try. Good gripper maintenance also calls for cleaning excess chalk from the knurling of the handles with a stiff, nylon bristle brush.
I like crickets and all, but my gripper is sounding like one. Is it defective? Can I do anything about it?
Not to worry: sometimes the edges of the coils on the spring rub against each other in just the perfect way to produce a creaking sound; it's not indicative of a structural problem, but if you find the sound annoying or distracting, a shot of light oil should dampen or eliminate it.
Is it cheating to put oil on the spring of my gripper?
No, absolutely not, but we appreciate that you are being so conscientious about this.
