corrosion protection coating pre surface grinding?

[knighty]

the company I use to sharpen mincer blades/plates at work complained they were dirty before....

I assumed they meant they hadn't been cleaned properly (meat stuck to them) so double checked the next batch

they complained again.... turns out they meant rust....

last batch just sent off I cleaned in citric acid before I sent them (worked really well, it was my first time using it)

but for the future... after I clean them, how can I protect the surface from corrosion?

I'm assuming they'll like oil/grease even less than they like rust?


I've stored them in veg oil before.... protects the surface and no need to worry about it poisoning someone's dog etc.


any ideas?

They'll probably be fine with them coated in light oil. They can wipe off the excess by hand if necessary

Ask them, they'll know better than the guesses here.

Food grade silicon maybe

Everything made at a mates place was dipped in dewatering fluid, I say everything I only had anything
to do with parts from the capstan. After being dipped the parts were then left in bins for whatever was
next for them[that was often grinding], I was told the dewatering fluid gave 3 months protection.

The dewatering fluid was clear and waterlike, it didn't appear to leave any residue.

Seems to be just a thin oil
