That sounds awful! Ammonia is known for its corrosive properties.Windex would work as well as anything else.
Shampoo or dish soap and water.
Are you mounting the tires yourself? Why not let the tire shop handle the stems too?

Same thing if the shop uses too much regular soapy lubricant even a not so powerful 2.4L Honda Accord manual transmission.DO NOT USE SILICONE ANYWHERE NEAR A TIRE!!
Silicone is so slippery that if you get some between the tire and the wheel, the tire could rotate relative to the wheel throwing off the balance! This will not go away and you have to dismount the tire off the wheel to clean the wheel - and cleaning the wheel takes some effort to make sure you got it all! It's better if you don't have to do that.
Some people spray or apply LIBERALLY and might get it on the bead area.This is about lubing a valve stem , not a tire bead ...
I will be doing some off-road driving and I prefer the flexibility the rubber valve stems provide ie less risk of damage from flying rocks . I do prefer the looks of metal stems but otherwise I have never had a problem getting accurate pressure readings on rubber stems.We opted for the rubber stem, but once home, I found it very difficult to get an actuate reading with the tire gauge as the rubber stem kept moving around. Took the van back to Discount tire and had them install metal stems as these gave me a much better and more actuate reading.
