How do I delete unused environments from my file?

How do I delete these?

After just trying to test how the model looks I noticed they are kept there.
All these increase my 3dm file size and slows the Save command performance.

Thanks in advance.

Materials too. This is very weird!

For materials you can use Purge command.

Thanks Mahdiyar,

Still I feel like a good X button on each material and environment will be better.

In materials\environments tab you can select any material\environment and press Delete key on your keyboard. Or you can select Delete from context menue.

Use the Materials and Environment panels to delete what you don’t want.
