Remove autofill / autocomplete first name and last name on guest checkout

[WISYWIG]

Hello

If a user does checkout as a guest, PS does fill in hist first name and last name in shipping address, because the user did enter these information in previous page.

How can I remove this autofill / autocomplete?

Thanks.

 

Using PS 1.7.x
