Sanding lubricant consensus?

Is there some rule here or just personal preference? I did a little research on the forums and here are a few of the replies you good folks made.

1.Yup, I use Simple Green and water (1:3 mix).
2.Window cleaner would rust my blades over night in the shop. I now use mineral spirits and it works good.
3.Hand rubbing at 220 with simple green or orange magic
4.I use Windex as a cutting fluid for 220 and 400, Cool Tool II for higher grits.
5.Water
6.I believe he was using kerosene with a little oil in it in a spray bottle for his lubricant.
7.Start with 180 going lengthwise and using Cool Tool 2 or Tap Magic cutting fluid
8.At higher grits you may want to use water as a lubricant. There's a saying "oil cuts, water polishes" seems strange but experience has proven it to me.
9.Not be difficult but I think it's the other way around: Water cuts, oil polishes.
10.Some cheap honing oil
11.Petroleum based (not paraffin) lamp oil makes a nice lubricant for wet or dry papers.
12.Kerosene and mineral oil
13.I use baby oil now, cheap and smell decent.
14.I have used WD-40, and lots of other stuff, but I find that good old Windex with vinegar is the best. It is not that standard blue Windex, but is clear.
15.I like Windex at the real fine grits, but ONLY Windex brand. I've tried a few others and they all reacted with the blue 3M tape I put on the finished side of the blade and caused pitting
16.Instead of Windex and when I make a slip joint with a Stainless steel. I will use really soapy water, Dawn dishwashing liquid. Seems to help out on the hard stuff and deep scratches.
17.I have found that Cool Tool works VERY well, particularly on the heavier grits. WD40 and Windex are distant second.
18.I like to use a mineral oil when I do the hand rub. I'll stop at 320 with the oil. Wipe the oil off and do another 320 rub with water and a little baking soda and continue with the finer grits and water.
19.I ran out of Cool Tool lubricant, today, while doing the hand sanding on five, W2 blades. I had a bottle of Avon's Skin so soft, on the shelf. I thought I might give it a try. This stuff will remove tar from your auto, almost as well as diesel fuel and has nice oil like consistency. It works really well. You only have to apply a small amount to do the job. I was cleaning up the residue from the PBC coating on these knives and the SSS broke the scale down and made the sanding paper cut really well
20.I usually like to use WD40 or TapMatic (Aquacut, Grainger cat no. 2C649).

Simple enough right? :confused:
Guess trial and error to find what works best for ME is the way to go?

Hey, my girlfriend sells Avon! I'll have to try that.

I've only used water, doing the final few passes with each later grit, dry. Works fine for me, but if something else works faster, I'm all for it.

It makes sense that Cool Tool would work, it's designed to float bits of steel away from the workpiece, right?
 
I never thought of using anything other that water. Oil makes sense as a lubricant, but I thought that machining coolants cooled via heat transfer? Or when sanding is it just a thin liquid that doesn't rust like water?
 
Hey, you're only half way through your research. Now you have to compile your list in order of most popular to least and state percentages. Such as 15% use ___, 10% use ___, etc... Make sure it all adds up to 100%! :D
 
I just used windex on a blade to sand from 220-400 and it seemed to work pretty well. Better than tap magic actually.
 
"Consensus" - that's funny! :D Good research though. I'm with Phil, you should tally up the stats and see what comes out on top. In your copious free time. I'm sticking with "water cuts, oil polishes" and I use Windex on the courser grits and Cool Tool II on the finish grits - 600 and above. I still haven't come up with a good way to rub out hollow grinds, so those get polished. :) Glad I don't do them often.
 
I never used any kind of lubrican for sanding so I bet I must be doing something wrong... :(. I usually polish up to 800 and never used any kind of liquid.

I'll stick with water. It cuts better than oil. There are some "ghost" scratches appearing at final grits when I use oil, but with water I didn't experienced that..
 
I like tapmagic or simple green. The cooling properties have little to do with using the lubricant for hand sanding. The cutting fluid works well because it holds the grit in a slurry when you're working it.
