Cleaning chef whites with oven cleaner might work?

I know that there is a high risk of the material breaking down but im at the last straw before bring home so of our cleaning chemicals. I was thinking since the oven cleaner uses lye( sodium hydroxide) which is a very costic chemical with a high pH. My chef coats have a large array of stains and one that i cant get to budge which is metal shavings from sharpening a knife. I have tried oxyclean, bleach, color safe bleach, dawn soap, boiling water and vinegat and lemon juice, and all the other stain removal tips that i have gotten, removed stains really well but not all of them. any ideas? and i cant buy new chef coats because they are my school coats from the culinary institute of america and i have to have these coats.
