WD40 Multi-Use Product

Bambu Lab recommends using “WD40 Multi-Use Product” for relubricating X and Y rails.
This product comes in a pressurized spray can. Has anyone attempted this?
I’ve found many YouTube videos of lubrication process, but none where someone is trying to spray about 5 linear feet of rail with a pressurized spray. Even with the straw nozzle, you’d be oiling your entire workspace…

not something I have used for this but if I did I would spray it on a cloth first and wipe it on. This is a flamable product so I wonder if they say the same for the H2D laser (seems like beam may reflect inside chamber) or if they have a recomended wait period?

I have used WD-40 spray with the straw. It goes exactly where you put the straw. Just give it a push or two and run the device up and down. Easy peasy.

Having used it myself for hundreds of other applications, I can say that even with the straw, the dispersal pattern is significantly larger than the rail area. It may go “exactly” there, but it also goes for a couple inches around it, and splatters everything beyond/behind a small surface as well.
Most lubricants for this purpose lay down a bead a couple millimeters wide. I just took out my WD40 with the straw nozzle and put it right up to a plastic laminate surface, and the shortest burst I could manage gave me a spot about 50mm I diameter, with some splattering to 100mm.

I bought a nail polish bottle with an included little brush, emptied and cleaned completely with acetone. Then I sprayed the WD-40 Multiuse in it. Now I have a fully controlled oil applicator.

That definitely sounds like it would work.
I’m just wondering what BBL’s intended method was…
We shouldn’t have to do all that, obviously.
And it’s telling that no one on YouTube is using this spray application (I’d love to see a video of someone doing so successfully!) and BBL tutorials haven’t even added a photo of such a process.

there is always the gallon option on Amazon for 30.00 US.
Thing is, these ads say original formula multi-use and claim it is good for lubrication. Original WD-40 is not for lubricating, it is for “water displacement” (WD) and the can doesn’t even mention lubrication. There are WD-40 products that do lubrication (WD-40 Specialist dry lubricant puts down a dry film and WD-40 Specialist 11 with silicone). I’m glad spraying seems to work for some people but as I said earlier, no matter what the product, personaly I would spray it on a cloth first (or something like ElektroQuark’s brillant idea).

Yeah I’ve noticed most pros seem to be using a silicone-based oil, which is probably what the original Bambu oil was.

I use “sewing machine oil” because I happen to have a bottle of the stuff. But any lightweight lubricating oil will work. Apply a few drops to a rail, on either side of the “carriage” that rides on the rail, and then move the head back and forth to spread the oil out.

You can just spray it all into a plastic bottle(mess control) and then pour it into a mason jar for long term storage.

In industrial settings, lots of lubes come in gallon or 1.6L unpressurized bottles. Probably something a print farm would invest in, and amounts to a lifetime supply for anyone else.

I came across this WD40 Pen on amazon, been thinking of try it, should be pretty clean not having to buy one gallon containers of WD40 or spraying into another container.

I spray WD 40 into a 10 ml e-liquid bottle with a thin tip. It can also be poured into a syringe with a needle.
