Using a dish washer or doing a sink wash ?

FWIW I live in a hard water area so need regular salt and rinse aid in mine even though I use finish powerball. I have lots of different cycles but everything goes in on a 1hr cycle and comes out perfectly clean. I put my oven bars in and they came out super clean. I have read ( on mumsnet) that some people put their toilet brush in I draw the line at that.
