Dear Szabolcs:
The Utilities`SubscriptSymbols` is a package ellaborated by Ted Erseck
that is in Wolfram Library Archive. You can to find it via Google (or
others). It permit to clean and to remove variables or functions with
subscripts.

Before to be charged the package:

In[1]: x[Subscript,1]=15
Out[1]:15

In[2]: Clear[x[Subscript,1]]
Out[2]:Message: x[Subscript,1] is not a symbol ....

After to be charged the package:

In[1]: x[Subscript,1]=15
Out[1]:15

In[2]: Clear[x[Subscript,1]]
Out[2]:


It occurs the same for functions with subscripts F[Subscript,1] ....

But this functionality is not implemented in Version 6.0 and I think
that is a functionality very useful.

I have proved to copy this package in version 6.0 but doesn't works
fine.

Does exist a solution?
