This might be easier to follow:
Then after the Naptha just put it away.
Next use the linseed oil and denatured alcohol - go light - just go over it.
Then you can go over it with some denatured alcohol and shellac.
You do not need to repeat the Naptha.
You can repeat the alcohol and shellac a couple times
you might need to go over it with the linseed oil and denatured alcohol if it doesn't go smooth any more.
