Stainless steel rollers: These do not corrode easily but you have to be careful when cleaning them as they are harder than most materials.

Seasoning: This is compulsory for wooden tracks and advisable for vinyl tracks. Follow the manufacturer’s guidelines carefully.

Lubricating: Apply a thin coat of silicone, then wipe it off thoroughly after allowing it to settle into the track for a few minutes. It is highly recommended that you do this outdoors where there is little wind and on a bright and sunny day as test runs indicate that less grease gets blown around under such conditions.
