content: Curious how most people take care of their tools, cutters, pliers, scissors, etc.Do most of you buy WD-40 and apply to everything once every while? Or do you use special oils and products depending on what you're using it on?

content: I have never found it necessary. Do you live in a particularly damp environment?Most tools are stainless steel (scissors) or have chrome plating (screwdrivers, pliers, etc). Kept indoors they stay shiny forever.Some tools like hammers and tin snips may be made out of carbon steel. To stop them rusting an occasional light coating of machine oil before storage should suffice. But common use and keeping in a dry environment should be sufficient most of the time.

content: Many of my hand tools are chrome plated, e.g., wrenches. Only a very few are stainless. Most of my tools are good steel, some of it hardened. Ordinary oil from use helps. I have quite dry skin and don't sweat on them much, which is an advantage. I do wipe them down with an oil rag. For longer term storage, I use LPS3.I do have some WD40 in the shop, but I do not use it often, except under my arms.

content: Quote from: Sekkai on August 18, 2018, 10:03:42 pmThen why didn't you say that in your first post?I believe everyone in this thread, including me, thought you were worried about rusting and corrosion. It is normal to apply a thin coating of oil on tools in a machine shop to keep them from rusting.If you want to know how to lubricate hinges, ask: "What is the best lubricant for hinged tools like scissors or pliers?"As noted, the answer is going to be light machine oil or sewing machine oil.

content: Some of the better products are gun care products of which there are many types and consistencies.For medium term corrosion protection they can be very useful while the thinner solutions offer better penetration properties. For stiff tool joints you want something thin to penetrate and flush the joint and pretty much any light petrochemical product is fine for freeing up tools....even petrol/gasoline. Then proceed to a proper light lubricant to maintain movement and minimize wear.One need consider non-staining properties which would be where the likes of clear lubricants like sewing machine oils could be more useful than many. I use a product from INOX, MX3 it's clear, food grade and it lingers.

It is a cleaner and penetrating agent, for example to loosen rusty bolts and free stuck mechanisms. After you use WD-40 to release something, you should always apply a proper lubricating oil afterwards.

content: I have had rust issues before, when having a poorly sheltered workshop. I have tried paste wax and parafin, and I am not 100% sure, but I think they do absolutely nothing. Oil, any oil, seems to be essential.For me, the most important thing was learning how to remove the rust. Doing it the right way will reduce future problems. They sell phosphoric acid by the gallon. You can use this to remove rust, and it leaves a block oxide layer. After rinsing and drying, apply some oil to soak into the surface, and this adds some protection. Even better if you use a zinc phosphate solution, phosphoric acid with zinc dissolved in it. This is sold as parkerizing solution already mixed in the correct ratios. You put the part in there and it will remove the rust. And it will deposit a protective layer thicker and more durable than the plain phosphoric acid.I parkerized the top of a cast iron saw table by covering it in sawdust and pouring on the solution. It worked wonders. The table gets some rust around the edges, but the top has been rust-free ever after.A lot of people use vinegar to remove rust. It does this great. And it leaves a patina, but it really doesn't add much protection.Another trick I learned about later but never tried is linseed oil. If you apply it to steel and then heat it up, it makes a really solid black patina. I suspect it's partly chemical reaction, and that there may also be some polymerized oil stuck into the surface.https://youtu.be/4ywqz3OWN4w?t=156Another thing to be aware of is the color of the rust. If your tools get a dark brown rust that is smooth/flat, it is sometimes best to just oil it and rub it down. Buffing with fine compound, if you must, or do the acid wash. But don't sand it off and leave a clean coarse surface. The dark brown rust is very benign. If you rough up and clean the surface, you can trade that in for destructive red rust. The dark brown stuff usually develops very slowly on well-oiled tools, IME. In days gone by, machinists used to grow a thin layer of this dark brown rust on there, on purpose, using steam and a card file to brush off the excess.If you are in a humid/salty environment, basically get used to having funky colors and stains on your steel. If you only concern yourself with just the red/orange or bumpy/rough/dusty/crumbly rust, you will save a lot of repetitive work for no reason. Any other stain that starts/grows is technically eating the steel, but it is also protecting it from the red rust which goes off exponentially once it sets in and is about the only thing that will eat down below the surface.If you must have bright and shiny steel, then get used to refinishing regularly. I'm sure you can find commercial products with fantastic claims.

content: It's important to note that there are different categories of tools. For some regular maintenance is required, while others have all the protection they need in the form of a coating. A manufacturer like Knipex typically has a bare or black model and a chromed model. The former needs to be maintained, while the latter doesn't. A bare model can have some advantages, like slightly sharper cutting edges.

If something's made of a tool steel that can rust I'll usually wipe it down with the oily rag after use. This has the advantage of being pretty harmless stuff to get on your skin.For bigger tools I'll spray them with CRC 3-36 as needed. As far as I can tell it's not that much unlike WD-40. Most of these type of products are mineral oil in a mineral spirits carrier. I like the pump spray bottles for less mess than aerosol spray.

content: +1 for snake oil. It's great!Honestly, the oil industry, at least at the consumer level, is quite a lot like the beverage industry. It's an extremely profitable sector which is 90% about product packaging and marketing/distribution. Beverage companies, new and old, Coke or Monster Energy.. not all of them, but MANY of the most successful ones spend more on marketing than on their product. Like colored/sweetened water, we essentially have a limitless supply of light oils as a byproduct of world demand for fuel oil.This is the perfect industry for politicos to hand contracts out to their chronies. I personally know a company that gets multimillion dollar government contracts. There's no extensive research and development department. There's no laboratory. It's 4 guys who know someone who knows someone, mixing and bottling oil and grease and getting a bit bite of government cheese.The ACF50 aircraft stuff, I'm sure started out like this. I bet 99% of their business is beaurocratically mandated through government or other monopoly policy makers. It's cute they even have a website and/or sell through other distributors to individuals.QuoteI found this:QuoteThere's one reference that claims whale oil as one of the original ingredient.All in all, this list sounds a lot like an average guy mixing up w/e he has lying around his garage and seeing if it works.And I bet many commercial oils are no different, other than they would be putting way more attention to the cost of the raw ingredients available to them at the time. In many cases they are using the less refined precursors to stuff that even has a name. "Hydrotreated light petroleum distillate." What is that? Maybe it would produce some lighter fluid, some mineral oil, some other stuff if further refiend. Or we can buy this stuff for 1 cent a gallon, add a drop of otter semen, and call it CR90.

content: It should be noted that actual lubricating oil designed for best performance is not just any old oil, it is oil specifically designed for the lubricating job. In particular, mineral oil is refined to keep all the long, straight chain molecules and to remove the aromatic and cyclic molecules. Therefore any random oil you happen to find (like lamp oil) isn't necessarily lube oil.A good source of actual, purpose designed lube oil is motor oil.

The mineral oil is unchlorinated and conforms to the specifications of US Pharmacopeia XX."There's also isohexane as a thinner in the aerosol variant, 14% of the product. This is not something you want to intentionally ingest.QuoteI find it curious how many tests there are between these various products without some known quantity as a control. Comparing snake oil to snake oil, the winner is very unsurprisingly going to be snake oil. Ed's Red, I suppose is generic, but even ATF is... well what is ATF? Add something in there that is generic.

content: I don't like oily tools for hobbies or electronics because dust sticks to them and get messy and dirty.My mechanic tools are oily anyway from just use.But if I put them in storage I just use some ATF .It's worked just fine for years.For Air tools I use the proper air tool oil because it dosn't build up and get gummy.Over the years I find diesel works just as well as a penetrating oil for rusty bolts or seized tools as anything else.Copper coat to prevent re seizing. For extremely seized bolts nothing works better than a oxy-acetylene torch.I have used WD-40 as a quick fix for engine distributors that have been exposed to moisture or fogging small engines for storage but I don't keep it around much. Graphite spray for door locks because it dries and dosn't collect dust.Most other on the shelf specialty lubricants , anti seize compounds and additives may as well stay there on the shelf.I've tried just about all of them and they're simply not worth the money.What I found was to be careful using engine oil or gear oil on plastic or rubber parts.Petroleum based oils can soften some plastics and swell some rubber parts. For instance, pouring engine oil,ATF or any thing other than brake fluid into your brake system will destroy it completely.I know this isn't an automotive forum just my 2 bits of experience.
