down at the po we just sprayed some 409 and held it upside down, so it wouldn't hit the membrane. then use a medium flat blade screwdriver to clean between the keytops we did this about once a month cuz of all the dust on the workroom floor. never had a failure. here at home I once tried taking one apart that had already failed. I washed the PCB with alcohol and a lint free q-tip . it worked for about 2 weeks. good luck, Jerry ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!
