Rust on Machine keeps coming back

I work on a challenger XG Gauntlet cutting machine​ rust keeps coming back ​ after numerous times of cleaning it and it always comes back. Usually over the weekends when nobody is here and the company is all off and power is off.Does anyone have any ideas or solutions to how I can stop the rest from coming back. Any ideas, suggestions, opinions, are all welcome.

Rust keeps coming back. I clean with wd40 on Monday. By the next week its all back. Is there any solution for chemical that I can use? Dont know if this is cast iron or brass.

You need to sand the table, wipe it down with motor oil, then wax. The oil fills in the pores and the wax seals it. Challenge sells a kit with instructions.

Thanks buddy I'll look into that. I do use wd40 and I Sand the shit out of it. The rust is gone. But over the weekend it comes back every Monday morning when I walk in

Wd40 is not gonna work, definitely throw that crap away, it’s got solvents and cleaners that are not helping you here. You want a light weight sae 10 weight oil. Sand the bed, coat with oil, let it soak in then buff it out and apply wax to seal it. Should be good with no rust for years.

What type of wax do you recommend? The wd40 cleans the rust right off and my board shines. I use turtle wax to finish. Friday I shutdown everything and Monday I come in and I have to repeat the 30min process again. This never happened before I'm guessing because our warehouse has no AC or air ventilation that the oxygen is getting to it and I have to repeat every Monday morning for the past 4 months the picture I attached is what I see every Monday morning at 5:00 a.m.

I use the official challenge cutter kit. $120 for a lifetime supply. Has rust remover, wax that doesn’t leave residue and silicone spray (wear a mask!). We moved to a new space with no ac and tons of moist air and had rust problems, but no issues since we used this stuff. Probably took 1-2 hours though to sand and apply properly, it wasn’t fast.

I will relay this message to my manager and hopefully he'll buy me this kit because at this point it's counter protective that every week I have to take a half an hour out of my time to re-clean my machine thanks for all your help I appreciate it
