It is stated in the description of the ‘Energy body/ Aura deep cleaning’ audio that it is not suitable for after using subliminals or energy works.
How soon after would you suggest? Should I dedicate a day to take a break from my stack to listening to this?
The answer is in the description of the “Energy body/ Aura deep cleaning” field 
At least 3h; so, you listen to your subs, wait 3h, then you can listen to Aura Cleansing (which does delete subs, morphic fields, other related audios or content and any energy work listened to or used in the previous 3h).
Thats it.
