A couple things about this.  

One, the optional touchscreen for the 150-II doesn't have the array of
holes, it has a smooth piece of IR-transparent plastic over the LEDs
and sensors.  So, you don't have to vacuum out the LED/sensor array,
just wipe it off.

Two, it took about a year or two for 150A/B in an office environment
to clog up.  We had them under maintenance and the HP guy came out
with tools that sucked and blew, and with little clear plastic covers
of about 2-3mm thickness to sit over the bottom row of holes.  These
matched the curve of the CRT and were molded with two pegs poking down
to sit in a couple of the LED/sensor holes.  Having seen what was
done, I pestered the HP field service guy for another dozen so we
could outfit the rest of the 150A/Bs without needing to place service
calls.  I'm guessing the actual HP part is somewhere between LOOK R at RE
and unobtainium now, 20 years later.

As you might guess from the above, you can do that.
