Visual Studio clean solution doesn't delete all dlls / project reference getting moved

c# visual-studio-2008 build dependencies project-reference

I have a VS 2008 C# web app with a bunch of project references to custom dlls. These are all at a relative path from the web project. Recently I've noticed that Clean Solution removes some, but not all, of the dlls from the web app's bin\debug folder. For example:

<Reference Include="TowerCo.Utilities, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\..\Components\TowerCo.Utilities\bin\Debug\TowerCo.Utilities.dll</HintPath>
</Reference>
<Reference Include="TowerCo.WebControls, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\..\Components\TowerCo.WebControls\bin\Debug\TowerCo.WebControls.dll</HintPath>
</Reference>

The first one works normally (clean cleans it, new versions copied to web project on rebuild) but the second does not. A side effect is that I don't automatically pick up changes to the dependency.

Thanks for any help.

It only seems to delete files it 'knows about'.

For instance old library files, and old references after having renamed projects are still there. Very strange. I always assumed 'Clean' was just a straightforward delete - and I don't quite understand why it isn't. Go in and check each folder by hand if in doubt.
