Open drier with right tool (6)
I believe the answer is:
trowel
'open drier with right tool' is the definition.
'trowel' can be an answer for 'tool' (trowel is a kind of tool). I am not sure about the 'open drier with right' bit.
'drier with right tool' is the wordplay.
'drier' becomes 'towel' (I've seen this before).
'with' means one lot of letters goes inside another.
'right tool' becomes 'r' (I can't justify this - if you can you should believe this answer much more).
'towel' placed around 'r' is 'TROWEL'.
Can you help me to learn more?
(Other definitions for trowel that I've seen before include "Platsterer's tool" , "Small gardening tool for lifting plants" , "Small hand tool for garden" , "Hand tool for plasterers or gardeners" , "This makes plaster spread" .)
