Great find.  I love it when someone comes up with ways to recycle/repurpose common household items. 

Sounds like a good idea.

I have got to start saving those things, now that you have put the idea in my head. Big thanks.

A lot of talk about dryer sheets, not all of it suggests it's a good idea.

Are Dryer Sheets Safe to Use?

And now my trains smell April fresh.😁

After many years of working in hi-tech manufacturing, I got a good understanding of why its not a good idea to use wipes or cleaners not designed for models, electronics etc.  I use the products in the picture.  If I need a chemical and depending on the application, then either alcohol, electronic contact cleaner, acetone or goo gone.  There are residual substances on dryer sheets that will react over time with bad results.  Remember, its a used dryer sheet, not a clean wipe.

I use them for grass on my train layout.  Pin them to a foam sheet and lightly dust with Rust-oleum Summer Squash and Camouflage olive green.  After reading GRJ's post I think I will suggest to my wife to use some of

the safer choices tho.

A firefighter friend of mine told me that drier sheets are a major cause of lint fires in your dryer due to the fact that they contain parrafin.

Full disclosure, I do not own any stock in any dryer sheet company.  I just had some old Lionel UCS track that was in a box, wanted to test some couplers and operating cars.  I pulled it out, took a dryer sheet to clean it up and was surprised how much better it looked.  I wiped down the outside of the control switches and it shined up nicely.  The whitened cable became cleaner and much more pliable.

Please do not do anything that you feel is unsafe.  I have not tried it on any electronics but thought if I could easily take years of crude off some of the old equipment I had in a box with sheets you were just throwing away, it might be of interest to you.  I did not try it near any electrical circuit boards or rub hard or long.   

Please do not do anything you think is risky or might damage anything, be safe and err on the side of caution.

Here are pictures of the cleaned USC track and control.

I did wipe off the top of my  atlas track in my layout and the sheet cleaned a noticeable amount of dirt on the surface.
