How to Remove Meta Tag Keyword and Description from Product Pages?

I am useing light-responsive theme,  How to Remove Meta Tag Keyword and Description from Product Pages? Only keep Title Meta Tag at product pages.

We  should edit the “customer/meta.tpl” that is used by your theme.
Now the theme is “light_responsive”, the file is “skin/light_responsive/customer/meta.tpl”.

{if $printable}
<meta name=”ROBOTS” content=”NOINDEX,NOFOLLOW” />
{else}
{meta type=’description’ page_type=$meta_page_type page_id=$meta_page_id}
{meta type=’keywords’ page_type=$meta_page_type page_id=$meta_page_id}
{/if}
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″ />

to:

{if $printable}
<meta name=”ROBOTS” content=”NOINDEX,NOFOLLOW” />
{elseif $main eq “product”}
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″ />
{else}
{meta type=’description’ page_type=$meta_page_type page_id=$meta_page_id}
{meta type=’keywords’ page_type=$meta_page_type page_id=$meta_page_id}
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″ />
{/if}

Another file that may be used on your site is this one: “skin/common_files/customer/meta.tpl” for other themes.
