Old men by hotel getting tip for trouser press (6)
I believe the answer is:
exhort
'press' is the definition.
(I know that press can be written as exhort)
'old men by hotel getting tip for trouser' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'men' becomes 'OR' (military abbreviation for Other Ranks).
'by' means one lot of letters go next to another.
'hotel getting' becomes 'h' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tip for' says to take the initial letters (one end or tip of the word).
The first letter of 'trouser' is 't'.
'or' after 'h' is 'hor'.
'ex'+'hor'+'t'='EXHORT'
Can you help me to learn more?
(Other definitions for exhort that I've seen before include "Urge strongly and sincerely" , "Call" , "Strongly urge (someone to do something)" , "Give great encouragement to" , "Entreat earnestly, urge" .)
