This procedure will delete any row for all columns that are null ignoring the primary column that may be set as an ID. I hope it helps you.

DELIMITER //
CREATE PROCEDURE DeleteRowsAllColNull(IN tbl VARCHAR(64))
BEGIN
SET @tbl = tbl;
SET SESSION group_concat_max_len = 1000000;
SELECT CONCAT('DELETE FROM `',@tbl,'` WHERE ',(REPLACE(group_concat(concat('`',COLUMN_NAME, '` is NULL')),',',' AND ')),';') FROM INFORMATION_SCHEMA.COLUMNS WHERE table_name = @tbl AND COLUMN_KEY NOT LIKE 'PRI' into @delete_all;
PREPARE delete_all FROM @delete_all;
EXECUTE delete_all;
DEALLOCATE PREPARE delete_all;
END //
DELIMITER ;

Execute the procedure like this.

CALL DeleteRowsAllColNull('your table');
