Removing odd parts of degaussers makes things simpler (5)
I believe the answer is:
eases
'makes things simpler' is the definition.
'removing odd parts of degaussers' is the wordplay.
'removing odd parts of' means one should take alternating letters (letters in odd-numbered positions removed).
The alternating letters of 'degaussers' are 'EASES'.
(Other definitions for eases that I've seen before include "Facilitates" , "Softens" , "Relieves, lightens" , "Assuages or slackens" , "Makes more comfortable" .)
