Cleaning a clogged espresso machine Portafilter Can anyone recommend a method for cleaning the clogged holes in a "Basket" of an espresso machine Portafilter? I had this problem with both DeLonghi and Saeco home espresso machines.

For example, in Care of Saeco Pressurized Portafilters (regarding 
Saeco Manually Pressurized Portafilter) they caution against using metal pins. 

Any suggestions of methods or cleaning materials?
I alone on the planet seem to have solved the endless problem of cleaning the fine holes of an espresso portafilter, or a Moka express fine steam filter.  None of the liquid or abrasive cleaning apps work, period.  Instead, in the past, one had to use a pin to poke out the minute holes — task so laborious and hopeless than most espresso and Moka machines in the world are hampered by limited filtration.

No longer.  The pin-holes are plugged with coffee fibre, which burns.  Place the filter over a gas flame, either side, for 10 minutes, tapping it with tongs occasionally, and bingo... 
A CLEAN FILTER.  All the minute coffee fibre plugs burn or pop out.  Best to use a small coffee pot rack on top of your smallest hob gas burner for this.  And metal tongs.

Will I be knighted for this?
