Delete duplicate and original row

[JStiehl]

Is there a way to delete rows that are duplicates (both the duplicate row and
the original row), so that I am left with only rows that are completely
unique within a spreadsheet?

Duplicated in one column or many?

At most, there would be two rows with the information in all 29 columns of
the rows being identical.

Like pulling teeth here.
AND, would these blanks always be located in the same column(s)
Maybe send your file to me with this msg and COMPLETE explanation.
