Pro-cleaning of openings for a water drain

No welded seam exists so tight that water there could not get. For this reason in all hollow profiles in the car openings for a water drain are built in. If they got littered because of dirt or too diligent drawing of anticorrosive protection of the bottom of the car, getting water cannot flow down any more and, as a result, car corrosion from within begins. Especially dangerous places are body longerons.


  1. Regularly to clean openings by means of brushes for cleaning of tubes («ершик»).
  2. If the car is equipped with the movable hatch, it is necessary to supervise in addition opening drains in a roof, see above.
  3. For cleaning – in front from above, behind from below – the old shaft of a drive of a speedometer approaches.
