Cleaning Engines
Allan has a question for readers:
“Hi, I live in an area with high sulphur content and have a few engines that are getting slow and are showing signs of contamination around the brass copper etc and want to clean this off but not sure what to do or use? Any help please.”

Use an electronics cleaner spray..it will evaporate almost immediately. On stubborn areas, use a toothbrush and respray washing it away.
The engine cleaning wire brush that clips to your track rails do a good job and with just a touch of spray they are talking about should clean these wheels very good. from Newman Atkinson
To remove corrosion on brass, copper and most metals, ordinary household metal polish will do a good job.
Alternatively, a small rotary steel wire brush in a dremel or similar.
If cleaning rails, wheels and pickup contacts is not sufficient, it may help to dismantle motors and clean the brushes and commutators. This is a fiddly job, but if you have the tools and skills, can prove to be well worth the effort.
