I'm having problems with the points of these Peco turnouts (N Scale) failing as far as electrical contacts. I have used 99% Isopropyl Alcohol and Deoxit D5 (not together) on the contact portions of the points to a limited success, but the problem returns after a week or two (I don't keep track of the date I clean specific points). I use a miniature foam applicator I got from MicroMark which works ideally to apply the liquid. I have read about at least one other modeler that had the same issue and he scraped (so to speak) those turnouts for something else. Anyone else have this problem and/or offer another solution?
