DeOxit products are good for contact cleaning. I have a Rigol scope and it works well.

hey folks , so I'm startin to get a bit more serious bout buying a new
oscilloscope . Does anyone have any experience with any of these Hanatak
, Rigol , Iwon , FNIRSI or the like ? I'm also lookin at some of the 100
MHZ Tek TDS scopes . MY newest scope is a Tektronix T922 with a dead
channel . I really like the size of these newer scopes I mentioned .

Also whats a good contact cleaner ? I figure I'd at least try
cleaning the contacts to see if I can revive that 2nd channel . I hate
to have to resort to my 1950's round CRT Heathkit scope ( though it's
the only one out of 4 that work )

thanks
