List functions: How to remove similar values/strings from a list

Hello

I'm stuck with the following: I created several lists and want them no loger to show similar values or strings.
p.e. my list looks like
93,97,101,104,105,107,110,111,113,93,111
each of the values 93 and 111 occur twice in this list. which function (or whatever?) removes these two values though the list looks like
93,97,101,104,105,107,110,111,113??

I would like to do this as well with a list containing names. p.e
tom jones,kathy winter,daryll hana,steven jobs,hillary hill,joshua graves,hillary hill
where hillary hill occurs twice. my list should look like
tom jones,kathy winter,daryll hana,steven jobs,hillary hill,joshua graves

thank you very much for a short solution!!!
