chose your words carefully. This is a Technical Forum.
I let the first bs go but since you double downed and went to large font I have to step in.
Disagree if you want, but do so politely. Please don't use bs in this forum.
Remember not all posters will agree with you and it's best to let it go after the first attempt and move on.

Rules,
SPECIFIC TO THE TECH FORUMS
The tech forums (Ar15,AK47,Handgun,Armory,Training,Outdoors) are more "formal" and actions permitted in the GD forum aren't permitted there. These forums are there to share information and as a result, trolling, heated arguments,insulting others,etc won't be ignored.

Fair enough although I don't think there was anything "heated" or insulting.  My point is common sense seems to be not so common in many parts.  Drinking too much water can kill you and I know people who have seen it but there aren't any warning labels on water bottles because just about everybody can figure out that you shouldn't drink 5 gallons of water per day...  and I don't know anyone who would advise against drinking "normal" quantities of (safe) water because it might harm you...

I'll make an effort to play nice (but sometimes it's hard!)...

One thing isopropyl alcohol is very good at is drying your skin, even at 50% concentration.  It can dry your skin so thoroughly that the skin breaks down and opens cracks...  You have to keep your skin in contact with liquid IPA for an extended period of time for it to go that far, but it can happen.  So unless I’m ONLY wiping off some bit of goop (or just removing Sharpie markings), I wear gloves when I handle IPA.

As for how the different concentrations of IPA work, I think 70% is too weak.  I tried to mix a little lanolin with 70% IPA, and there were a lot of settled solids.  It clearly didn’t dissolve the waxy content of the lanolin as well as my 91%.

Similarly, I made up some lube with anhydrous lanolin (a thick, nearly solid material) and 91% IPA.  It mixed OK when the anhydrous lanolin was warmed up, but since this stuff is mostly wax and almost no oil, the waxy content settles out and must be warmed up before it is again suspended enough to spray.  I put the spray bottle in very warm water for a while then vigorously shake it, and it stays mixed until it cools.

<Removed>again.

I remove a post, stated why it was removed, post the forum rules, and you see fit to post it again?

I don't understand how you thought that was a good idea.

That bad idea was the thread killer. Don't do that again. dryflash3

I think you have that backwards.

Red bottle is ISO-HEET, iso standing for isopropyl alcohol or isopropanol as its referred to in their older FAQ

Yellow is the methyl
