Bill Nielsen posted:I think the point is being missed here. The question is whether or not RnT and it’s sulfur additives are causing chemical/corrosion damage to bronze or brass components in typical model train applications. Whether or not it works well in your chainsaw, farm tractor, or semi-truck u-joints is pretty much irrelevant unless those items are made of brass. The negative effects of sulfur on copper, a major component of brass and bronze are well documented.
And I as I reported earlier, Using RNT on a 70 year old solid brass worm gear (which has had much more use than any toy train on the planet), for the last 25 years (or whenever RNT first became available) has yet to see any ill effects on that solid brass worm gear. You need (significant) heat for RNT to really start doing some harm on yellow metals.
We had our reservations at first also but after discussing the application for which RNT was being used, we were assured the grease wouldn't be an issue. 25 years or so later, "the proof is in the pudding".
