How do I combat rusting on my X-Carve?

UPDATE: Here is how I cleaned the rust on my X-Carve

As you can see in the attached pictures, I am already experiencing quite a bit of rusting on my X-Carve after only about a month of use. Should I be worried about this? Should I use any chemicals to clean it and prevent any future rusting? Here is summary of the conditions the X-Carve is used in:

Location: I live in Sherman Oaks, CA and the X-Carve is located in my garage.
Air Circulation: I have limited air circulation inside the garage when the garage door is closed and use an air conditioning unit (seen in the first picture) as well as other small fans to blow cool air around me while I work.
Air Quality and Humidity: I have little if not any humidity around the X-Carve in the garage, however I do have a problem with hot air being trapped in the garage when the garage door is closed, which I suspect could be the main cause of the rusting.
X-Carve Cleanliness: I regularly check all the moving parts and clean any dirt off the X-Carve, but do not apply any spray on cleaner. The main goal I have when cleaning is to get rid of any dirt and keep the CNC dry.

Any suggestions on how to go about cleaning and preventing this would help, Thanks!

Wow i’ve never seen that, are you on the beach/ocean? how long have you had your machine?

I am in the San Fernando Valley (Sherman Oaks) about 10 miles away from the beach, and I only have had the machine for a little more than a month. Here is todays weather:

I have used a product called Penatrol on bare metal parts to help protect them from rusting. You can get it at Home Depot or Lowes.

This is what I use.

That’s not normal for any California air quality. I live in san fernando valley, Anaheim hills, pomona. non of my equipment have this problem. Something wrong what you’re doing. Either cleaning chemicals you’re using or similar. Use that T-9 or any silicon based lubrication to clean your machine.

Thats what is confusing me as the only thing I am using while cleaning the machine is a dry rag with nothing on it. When I start using the t-9 should I wipe it on then off, or should I leave the lubricant on as a protective coating?

i use wd-40 on tools that go into storage just wipe them down with a wd-40 coated rag
thats what wd-40 was made for to begin with and the price works for me

Check all chemicals in the garage — Probably you have an imperfectly sealed container of something such as muriatic acid which is causing this.

If you can keep your machine in an enclosure you could use mothballs to inhibit rust.

that was what it did when i cut and pasted the link lets see what it does for my youtube channel

i tried the ones you used they didn’t work for me either
just dont know and by the way sorry for hijacking this thread

are you logged on to your amazon account if so try signing out then cut and past the link thats all i can come up
with and place the link on a line of it’s own

Ok, so I just ordered some Boeshield T-9 from and will post back with any questions I may have. In the mean time I will clean up any open chemical containers I find and see about enclosing the CNC better. Thanks for the help everyone!

I agree with @WillAdams, check your garage for anything leaking. If you have a pool and store pool chemicals in there, if you use any kind of acid for anything else, you may want to relocate the bottles and/or bag them up.

I’m pretty much an expert in abnormality, just ask my wife, and I say that thar’s not normal. :smile:

I am in northern Mn and at times the summer humidity from the 400+ lakes within 30 miles will make you think that you are swimming rather than walking. No rust issues here in my non air conditioned work space.

I tend to agree that there must be some sort of airborne contaminant involved, or being it’s a cooled space is there any evidence of condensation on metal parts after a few trips in and out of the space or if the door has been open for any length of time? (cool surface + high humidity = condensation + salt air = rust)

I agree with the posts above, my X-Carve was in my shop in the Georgia heat and humidity all summer and there is not a speck of rust. There has to be something causing the rust, as posted above, check for chemicals. I once had a bottle of muriatic acid (concrete cleaner) in my garage, the lid was loose and it caused the metal shelving it was on to rust in a radius of about 4 feet.

That looks like the problem I had earlier this summer when I was storing pool chemicals (chlorine) in my shop. Even though the tablets were in a “sealed” plastic bucket, I started having rust issues everywhere in the shop, even in the opposite corner. Once I moved the bucket outside, new rust covered articles stopped appearing. Unfortunately, once rust was on an object, it has been tough to completely eradicate it.

I regularly use boeshield as shown above as a protectant on my woodworking machinery and have been pleased. None of the flat surfaces I had sprayed with it had any evidence of rusting.


I have just got around to cleaning the rust on my spindle today. Here is what it looks like now:

What I did was apply a light amount of WD-40 to a Scotch-Brite® Heavy Duty Scrub Sponge and gently touched it against my spindle while it was rotating and it seemed to get rid of the rust pretty quickly.

My question now is, should I apply the Boeshield T-9 using the same method: Applying it to a rag and rub it against the rotating spindle, or should I apply it to the spindle when it is not moving? I would think the moving spindle would help produce a more even coat and help air dry it at the same time, but I am not familiar with T-9 so I may be wrong.

Another thing is do I need to remove the WD-40 completely before using the T-9 or can there be a small amount of WD-40 still on the spindle?

I’m in Venice, a mile from the beach, and am finding rust on all my screw heads as well. It’s in the garage with skylight and a wall vent. I just noticed it tonight and have added something to coat the fasteners to my Home Depot list for tomorrow.

Otherwise…I hate to think of having to swap out all the fasteners for stainless.

I actually have the same style garage layout, with a single skylight and a wall vent on the back wall.
