Strait from WD-40's web page: How long does WD-40 Multi-Use Product last after application? While this may vary depending on the application, WD-40® Multi-Use Product remains effective even after it appears to dry. Air tool oil could also be an acceptable substitute as it is also a machine oil that does not evaporate although expensive and comes in way to big of a container for this application. PB Blaster lasts longer but will eventually evaporate also. But for anyone that has used this stuff a lot will know it is a poor long term lubrication. The can actually says it lubricates, cleans, protects - I have yet to see this, Penetrates, and displaces moisture. Spray WD-40 on a door hinge, car or house, that squeaks and with in a couple of days it will squeak again.
#BLASTER AIRTOOL OIL PC#
I am drawing on 19 years of being an auto mechanic and fabricator along with being a PC tech. Spray a spot of WD-40 and 10 -15 mins latter it is gone leaving the residue. If WD-40 leaves a residue after evaporating the lubrication provided is not enough to keep items lubricated. It is meant to help loosen stuck or stick items for removal and then proper lubrication applied.Įther way, sealed bearing or open, WD-40 will evaporate and is no good for case fans because of this reason. Never recommended for anything that needs constant movement. This type of oil is meant as a penetrating oil and not meant as a permanent lubricant. This is an unavoidable fact, unless you want to keep buying new fans. Case fans every once in a while need the blades removes and the impeller shaft and bearings cleaned. Any oil will eventually gum up due to impurity's getting in it. The stickiness of Chain Lube has allowed me to lube the fans less. The point of oil is to provide a slick barrier between the parts to prevent ware. I have not seen any slow down in blade RPM's nor any Ill side effects that you mention. The point is to keep the oil on the bearings. I would never recommend something I have never used and tested myself. I have used this lube for years and never had a gumming up issue, this is why I recommend it. Chain lube i sticky tho and would tend to gum up the bearing.as a side note the oils i recommend are to lube a sealed bearing fan where you peel up the lable in the center of the fan and add a couple of drops.if you are lubing any other fan a drop or two of wd40 works,but due to the design of those fans it wont last very long.
