Injector bore
Hi Guys,
Have and engine that has been sitting on a stand for a few years with the injectors out. Can I use fine emery cloth or will the injector brush core kit be enough to get rid of those light surface rust?
Thanks

As a general rule of thumb, I start with the gentlest method of rust removal first and then slowly increase the level of abrasiveness until the job is done. I would be super careful on this one since bore size and circularity is critical to injector o-ring sealing. So yeah, start with the brush first.

I would pack something it the bottom of the bore to close of the injector tip hole, then I'd use some maroon ScotchBrite on an arbor chuck in a cordless drill. Should clean up rather quickly. Clean the bores...good.

There will be no corrosion in the cups.
That light surface rust at the top isn’t going to hurt as much as ANY kind of abrasive you put in there. You are almost certain to mess up with anything more than a fine scotchbrite pad.
Just wipe that out with an oiled rag and stab some injectors in there. If that ‘corrosion’ won’t catch a fingernail - it’s not going to compromise the sealing ability.
