Delete multiple hash keys

I often find myself writing this:

params.delete(:controller)  
params.delete(:action)  
params.delete(:other_key)  
redirect_to my_path(params)

The trail of deletes doesn't feel right and neither does:

[:controller, :action, :other_key].each do |k|
  params.delete(k)
end

Is there anything simpler and cleaner?

I'd be completely happy with the code you originally posted in your question.

[:controller, :action, :other_key].each { |k| params.delete(k) }
