Well my old 35 Rem 336 Marlin ( from 1964) came out of the gun safe today in excellent shape , However its Leather sling has a bunch of white spots all over it!
They wipe right off easily, but I need to know the best way to treat this? Any suggestions?

Remove the sling. Wipe it down. Put it out in the sunlight. Don't let it get wet. Don't let dew set on it, don't leave it out in the rain.
After a few days of bright sunlight (on both sides of the sling) and dry weather, spray it with Ballistol.

I get the "white dusting" if the leather isnt well oiled. Also can show up On wood surfaces. Never caused issues and whipes right off.

I was told by a leathersmith that the white is the oil coming out of the leather. I always thought it was mold until he set me straight.

I have always just wiped it down, saddle soaped it and was good to go. Usually have to do it every year or two. I just thought of it as regular maintenance. Kinda like cleaning the guns in the safe.
Saddle soap, as the name implies, is a cleaner. You should treat leather with Lexol to keep it from drying out. NEVER use Neats foot oil. It destroys leather over time.

Lexol is only good for chrome chemically treated leather (most of the stuff you find in the US today). Neats foot oil is only good for natural finished leather, like horse tack. Research the stuff done to Amish horse tack. You are dealing with apples and oranges here.

At the casting bench in the sky. RIP Bret.
Harness is routinely submerged in warm neatsfoot oil after cleaning to preserve it and it's supple feel. I agree that it all depends on the tanning process, but IIRC there are "all purpose" leather conditioners out there.

The good thing about the sunlight method is you do not need to accurately diagnose the problem.

If the substance on the leather is the oils & salts coming out of the leather, the warm dry air will help. If it is mold, the UV light and dry air will help. If it’s a little of both, the sunlight will help.

After the leather is clean and dry, then you have the decision of how to best proceed. Everyone has their own favorite method. Some folks like beeswax, some folks like mink oil, some folks like Ballistol, and the list goes on.

All leather is different and the methods to tan leather are different, but I’ve yet to see the sunlight method fail as a starting point.

Is there any easy way to discern between "chrome chemically treated leather" and natural finished?

Let's say a $60 pair of boots stamped "made in Honduras", that has some incredibly supple leather.

What I get/see is in no way oil or salts as I get same on gun stocks. So IMHO 100% a fungi of some sort. But I dont have a moisture issue as I dont see corrosion so its not a moist environment.

As for Nears Foot being bad. Its first I have read of and I have used both it and pure silicone on my leather since forever. It was my grand fathers choice. Never seen my items fall apart or disintegrate in last 45-50 years. I also have a couple of his holsters and slings that are still working but show use and wear from
last say 75 years.
Something else occasionally used is Mink Oil. Anyone still using it?

But Im open to something "better" what ever that could be.

For vegtanned leather a product called Obenaufs’s is a great protectant and preservative with none of the downs sides of neats foot oil or other products like Lexol. Lots of outlets carry it or check it out at obenaufs.com. A 2oz jar goes a long way.

Rubdown with a rag and application if Neatsfoot rubbed in and I have this. Generally Ill not see this come back after this application.

Wow guys you are all a treasure trove of great suggestions. After all the observation I think it is "sprew" because they are little round dots that wipe right off. This sling has been on the rifle since 1964 & I never seen it before ( Vegetable tan leather) I only finally got a gun safe about 4 years ago so before that all those years that rifle was on an open gun rack. 3 years ago it went into the safe! I know the humidity is low in the safe because I maintain that.....and this is the first time i seen it on that sling.
Going to work on it today, Thanks all!
