Replace all TAB and ENTER characters in a column

Question

Hi,
how can I replace all chr(9) & chr(12) characters in a column?
The following SQL replaces on one occurrence of TAB & ENTER, but my column can have many TAB & ENTER characters.
select trim(replace(replace(column1,chr(9),''), chr(13), '') from some_table;

Please cut'n'paste a sample from a SQL*Plus session, like this:
SQL> select 'a'||chr(9)||'p'||chr(9)||'c'||chr(9)||'!'||chr(13)||'!'||chr(13)||'!'||chr(13)||'!'
  2  from dual
  3  /
'A'||CHR(9)||
a       p       c       !
SQL> select replace(replace('a'||chr(9)||'p'||chr(9)||'c'||chr(9)||'!'||chr(13)||'!'||chr(13)||'!'||
chr(13)||'!', chr(13), ''), chr(9), '')
  2  from dual
  3  /
REPLACE
