If you mix smoke fluids from different brands together, would it damage the smoke unit? I was running low on MTH fluid and I decided to buy Lionel smoke fluid. The Lionel bottle was leaking so I decided to pour the Lionel fluid in the MTH bottle. I just think smoke fluid is basically the same, besides the Seuth smoke fluid and Williams fluid.
All the brands make smoke and most of us have put different brands down the smoke stack without any harm. So mixing them in the bottle won’t matter.
