No need to get into one if you skip the washing up! (6)
I believe the answer is:
lather
'no need' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'one if you skip the washing up' is the wordplay.
I cannot really see how this works, but
'one' could be 'the' (both can introduce a definite example of something) and 'the' is located in the answer.
The remaining letters 'lar' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to get into' is the link.
Can you help me to learn more?
(Other definitions for lather that I've seen before include "Frothy bubbles from soap" , "Froth formed by soap and water" , "Panic" , "Whip up froth - tizzy" , "Frothy suds" .)
