A fast and effective method for cleaning and repairing the shell-spar glue voids of a wind turbine blade, comprising the steps of detecting voids, raising the turbine blade at an incline, drilling holes into top and bottom ends of the void, injecting cleaning solution into the holes, and allowing the cleaning solution to drain out of the bottom holes and drain holes at the tip. The void is then inspected for oil by FTIR spectroscopy. If oil is detected, additional cleaning steps are performed comprising injection of a second cleaning solution into at least two holes of the void followed by a rest period, washing the holes with water via a pressure washer, and drying with compressed air. The blade is then inspected for oil and moisture, and when clean, adhesive is applied to the void through the holes. |
