How to 'clean' the item or binding?

I’ve temporary added an item with modbus binding to test the serial port. Test was successful and I commented out this new item in my .items file and also commented out the lines in modbus.cfg, then restarted OH. After restart I noticed a lot of error messages from modbus binding (USB adapter was disconnected already). For me it looks like the previous configuration has been cached. How can it be cleared in the future?
