Cleaning out Textures and Materials

I’m new to Blender and have gotten into a mess with materials and textures. There are loads of them and I don’t know what they are. Can I clean them all out and make a new start on texturing? I don’t want to lose the mesh, it is quite far advanced.
Thanks,
Mick Berg.

Mick, if your materials aren’t assigned to any meshes (they will have a ‘0’ in front of their names), they will be ‘deleted’ when you close Blender, open a new file, or reopen the file. Make sure the materials are not assigned to any objects or meshes and save. Then press F1 and then Enter. It should clear out all the excess materials/textures.

Cheers!

Many thanks for a quick reply, I’ll try it.
