Dear friends,
In wireframe mode some extra lines (edges) are visible and this extra lines are reflected on a render view and make some weird reflexes (blots). In edit mode there are no extra lines.
Edit mode:
Wireframe mode:
Render view:
This lines are obviously result of adding modifiers (boolean).
Please help me to get rid off from this unusual creases.
Looks like you're using smooth shading. In that case try checking Autosmooth:
Maybe you'll need to adjust the Angle to get rid of faceting in other places of your mesh, but those edges should no longer affect the shading.
