Hello,
First off I would like to know why, of all things
would you use hydrogen.  This tends to explode when it
comes in contact with sparks.  Second if you are going
to use alchohol you should make sure it is as close to
100% as possible.  Electronics grade is about 99.9%. 
You can get 95% as some drugstores.
