BLACK-OXIDE FINISH OLYMPIC BARS.
The Black-oxide finish on your bar is quality coating but is not a rust-preventative. If neglected, your bar will do what steel does best: it will rust. You can wipe your bar down with a rag sprayed with WD-40.
If need be, you can clean the chalk from the knurling with a synthetic bristle brush from a hardware store. Do not spray WD-40 into the sleeves of the bar. Your sleeves are oiled with SAE-20 weight non-detergent oil. This oil is ideal, but 3-in-1 oil works too. WD-40 oil = mush. If need be, you can lubricate the sleeves once a month with a drop of SAE-20 (non-detergent) in the hole of the end cap and where the sleeve-collar meets the bar. Some will tip the bar on one end, apply oil on the sleeve (and the opposed) sleeve-collar end, wait a few hours and then repeat the process for the other side. This insures that the oil really works its way into the sleeve assembly.

Although your Ivanko Olympic Bar has been engineered to withstand some abuse, any Olympic bar can be bent if it is abused. You can read our research on Olympic bars here. If you bend your Olympic bar, we may be able to straighten it. If you damage your Olympic bar sleeve, we may be able to service your bar. We attempt to keep these costs as reasonable as possible. Please contact us with your product number, photos (often helpful), contact info, the name of the dealer from which you originally purchased your bar (if applicable) or other purchasing information.
In addition, we also offer replacement parts for your Olympic bar sleeve, should you wish to replace the sleeve fasteners yourself.
We are always happy to answer any questions you have concerning your Ivanko Olympic bar, so please e-mail us.
