That is my impression. The one, and ONLY, time I tried it on the layout it didn't take long for the DCS signal strength do drop dramatically! I then re-cleaned all the main line trackage with acrylic lacquer thinner, and everything returned to normal. Never used it on the layout again.
However it does seem to work pretty well on the electrical plug/connections for the outside heated birdbaths in the winter months.
