Need To Clean My Rails Again

Soon after I got back into slots again I read a suggestion that wiping plastic track with a cloth moistened with WD40 was/is a good way of removing accumulated dust. So I tried it a few times but gave it up because I thought it was the WD40 that had caused the rails to become sticky over time.

Then I read that cheap baby wipes are a good idea, so I dismantled the track, wiped each piece, cleaned the rails with a rubber and blew the debris off with airbrush propellent. At this point, all my cars got new braids before going back on the track. I only wiped the track infrequently, but after only about 4 months the rails are dirty/sticky again and I'm looking at having to go through the cleaning process again on 100+ pieces of track.

I suppose that I could get some of this wonderful Inox stuff I've read about to wipe on the rails to keep them cleaner longer (once I've cleaned them yet again), but I'd have to get it shipped from Australia which is hassle, not to mention potentially expensive. I'll have to replace the braids on 40-odd cars again as well.

What methods do others use for removing dust from plastic track? Is it the stuff I've been using that's causing the sticky rails, or am I missing something else? When it first happened, I thought it could be thrown-off toothpaste I'd used to mesh gears, but I stopped doing that before I last cleaned the track.

Any advice/thoughts gratefully read.

TIA
