Silly question

Is it true that if a clearblue test line is questionable on if it is an evap or positive, you can slightly wet the test and if after 1 minute the line disappears it was an evap, and if it remains the test is a positive line?

Sorry, I jave never jad an evap on any brand ever. I jave used many brands and either jad stark white negatives or positives. So, I am curious
