When the fuel in tank is below -10ºC you have to "check" the engine before top of descent; after that you have to "clean" the FOHE entrance putting the engine in idle for 30 seconds. Eventually, this "check" could lead to an engine rollback. If this is true, it seems to me that a previous "clean" of the FOHE entrance would be a good practice. Alternatively, if you are confident enough that putting the engine in idle will melt the ice, this "check" would be unnecessary.
