Stopping rust on machined surfaces

[Blackmarket]

We have a large paper trimmer at work that gets used occasionally. Due to the extreme humidity in the area, it gets surface rust built up on the machined surfaces and table area. We're in the process of (de-rusting) it right now. Any ideas on what can be applied when we're finished to keep the machined table from rusting again? It can't be oiled due to contaminating trimmed paper. So it has to be something that will go on and then dry. Thanks for your time.

SC Johnson paste wax

I use it on all of my woodworking machines.

Boeshield I use it on my cast iron tables, saw, jointer etc...

Black,

I think that anything that will really work well will probably contaminate the paper. That includes the paste wax. You are probably going to have to just clean it before each use and then reoil it afterwards.

That is why woodworkers use Johnson's paste wax (yellow can and can be found at Home Depot) because it won't 'contaminate' the wood

Silicone mold release spray.

There are metal treating procedures that will prevent rust, but on large machined surfaces, it could be expensive and is usually something that must be sent out to have done, not a D.I.Y. project.

Couple of alternatives. Store it inside a large plastic bag (they make them big enough for cars!) with dessicant bags inside. Also, VCI paper (Volatile Corrosi0n Inhibitor) may help, I use it in certain cabinets to help with black oxide tools. I am not certain on the latter if it will transfer to the paper or not. Probably also enhanced by an enclosure, even if its just a cardboard "hood"

Can you just paint it with clear coat? Or clear coat the paper contact surface and wax or oil the rest.

Johnson paste was us great. Cheap, contains no silicone which can mess up wood later if you're going to stain it. Lasts better that sprays.

lot of woodworkers I know love Boeshield, never tried it but I use the Johnson's paste was on my table saw, jointer, etc. and it works great and lasts a long time. added bonus is it works great to polish the woodworking projects when done...and it's cheap.

Another vote for Johnson's paste wax. I use it all the time on my woodworking machinery and as long as you buff it out well, it will not contaminate the materials (in your case, the paper).

 

[Blackmarket]

Everyone, thank you all for your responses. Didn't expect so many. Going to give these a try.

I use Metal Prep on all of my machines. The shear, mill tables, lathes, saw tables, etc. It not only removes heavy surface rust as a prep/cleaner for paint but, when left on, leaves a zinc phosphate coating that inhibits rust very well. It drys to the touch and will not contaminate the paper.

I have been looking at their Afterblast metal prep but haven't tried it yet. it may work better for this application.

I haven't had great results with Jonhson's paste wax. My machines still rust even with a couple of coats, but I'm in the Texas gulf coast and 90%+ humidity is the rule for much of the year. I'm going to try Boeshield next.

I use it on all of my woodworking machines.

I've used Boeshield and about all the others and have settled on the Johnson paste wax. Inexpensive, easy, available and it works, but you have to stay up with it regardless of what you use.

Shelia Shine is another option that gets mentioned in these type threads.

Edit: Shelia Shine may leave a film that is unacceptable for paper

Did anyone mention Johnson's paste wax? Yup. Just about everybody. Learned it from my grandfather. Love the old-timey packaging too.
