I thought these sensors are self cleaning where (after switch off or on switch on) they glow red hot to burn off any crap on the wire...I could be wrong but I suppose its still a good idea to clean them every now and again to make sure. Mine is 2 years old and never cleaned...LOL maybe I should give it a quick spray.
