You just need to use the alternate syntax for foreach. From the php manual:
The foreach construct provides an easy way to iterate over arrays.
foreach works only on arrays and objects, and will issue an error when
you try to use it on a variable with a different data type or an
uninitialized variable. There are two syntaxes:

As alluded to by @Michael in the comments, the CSS classes for widgets depend on the sidebar they're in more than the widget themselves. Those widget-specific CSS classes can be useful, but not when you're trying to style every widget.

Example with a search widget; uncomment the debug code to find the correct identifier.
if ( ! is_admin() )
add_filter( 'sidebars_widgets', 'remove_specific_widget' );
function remove_specific_widget( $widgets )
{
if ( ! is_single( 402 ) ) // Post ID, title, slug, or array of ...
