How to remove entirely duplicated rows in Query Editor

I have data that includes entirely duplicated rows - every column is the same. I want to remove them. Annoyingly I can't do it in the data source so I have to do it in query editor. 

I can't use the "Remove Duplicates" function becuase that only removes duplicates using a single column and that's not what I need as there are supposed to be duplicates in the columns. Here's an example:

I have a table with ID and Time.

ID     Time
1      10.00
2      10.00
3      10.00
1      11.00
2      11.00
3      11.00
3      11.00

It is only the last row that I want to remove - that's the only row with duplciates across all columns. If I remove dupicates using ID I'm left with the first 3 rows only and if I remove duplicates using Time I'm left with rows 1 and 4.

Currently I get around this by concatenating the columns and removing duplicates based on the concatenated column and this works but I was wondering if there was a native solution.

Thanks.
