Re: Mizuno JPX900 Hot Metal Irons
I have to say that my first ever (and probably my last) purchase has resulted in a very poor level of customer service. Mizuno have advised that the corrosion is not under warranty and that this is a result of the lack of care. I cannot agree with this comment as these clubs were brand new and used for the first time on Sunday 11th Feb and cleaned after the round then lubricated with light oil. So, corrosion occurred after one round and the clubs cleaned as quick as was humanly possible but then still corroded. The same occurred on the 9 iron this week, played and clubs and cleaned during the round and finished and finally cleaned and lubricated within 1 hr of getting home. Again more corrosion. This strikes me that there’s an issue with the irons that either Mizuno know about but won’t admit or genuinely feel the clubs hacve been abused. Either way the warranty does not apply. Not sure what to do other than not to play in the wet, clean the irons and keep them tucked up in bed at a nice room temperature. Very disappointed in both the level of customer service and the fact that the items aren’t of a required quality to withstand normal use. I had fellow golfers interested in purchasing the same but this experience has now put them off Mizuno product. Certainly did not have these issues with Ping and the level of after care needed/suggested. Dissatisfied and disappointed !!!!

That sounds very odd. Having owned 7 sets of forged irons by Mizuno over the years, I've never encountered the issue, all of them have been used. The only clubs I've had corrosion showing have been some wedges that have been hit thousands of times wearing out the protective coating.
Why are you adding oil? Doesn't that make a huge mess of things, especially when you need to remove it before a round? A good cleaning and drying with a towel is all you need. Do you use iron head covers?
My suggestion is you check what oil you are using and I'm willing to bet your problem lies right there. I'd simply stop applying it.

In fact the first club a PW was straight out of the box. I round, corrosion before I could clean it. This is something to do with the steel grade being used. It has been said that they are not as resistant as other steel grades. Let’s not get confused with the oil. That’s an instruction with the clubs for care.
The only time I became aware of rust spots was on a new set of MP59’s a few years back. I had used neoprene head covers which apparently keep in moisture. Once dried (and a touch of baby oil 
) I was able to wipe away the rust spots.
I’ve never used head covers again and haven’t experienced any further rust problems.

I also have rust forming on my JPX900 irons. When I reached out to Muzuno I was told that it was normal. The they said it was caused by fertilizer and chemicals used at my golf course. the also said that the irons aren't warranted because they are older than 1 year. I love my lrons, but I've been golfing a long time and have had many sets of clubs and nothing like this ever happened before. Muzuno needs to better stand behind its equipment and replace the irons. I'm reasonably sure my money didn't rust in their pockets after a year.
