Sparks under the wheels

[T-Lloyd]

should i return it or is it still fine?

An emory board is a bit extreme, it's to abrasive ' using it will put micro groves in your wheel sets that'll just collect even more dirt and grunge.
instead dip a Q tip in 91%alcohol and after ringing it out use it to clean the wheel treads . repeat this process until the Q tips remain clean.
You'll most likely go through a half doz.per locomotive but their cheap and most important safe and gentle on all wheels.

ok, just so im clear, i take a Q tip with the 91%alc and use it on each wheel until nearly dry then take a different Q tip and do the next wheel and continue until every wheel of each loco is done.

how often do you think i will need repeat this? - i have a medium size railroad (4x16') and its probubly running on average 10 mins a day but right now im doing some scenery and stuff so i can't run it.

also 99% will work? (all i  have)

When I mentioned an emery board for cleaning wheels I should ahve indicated that I use the back side not the grit side.
