A downhole tool including a resilient body configured to be disposed on a drill string, the resilient body comprising a plurality of radial blades having an abrasive coating, wherein the radial blades are configured to deflect when inserted into downhole tubing, and wherein the resilient body is configured to allow rotation relative to the drill string. Additionally, a method for cleaning downhole tubing, the method including inserting a resilient scraper disposed on a drill string into the downhole tubing, the resilient scraper including a plurality of radial blades having an abrasive coating. The method further including rotating the drill string, and contacting the resilient scraper to an internal wall of the downhole tubing. |

1. A method comprising:
inserting a resilient scraper disposed on a drill string into a segment of downhole tubing, the resilient scraper including:
a resilient body having a hollow core section and a center defined therein,a first blade coupled to the resilient body and extending away from the resilient body in a tangential direction, the first blade having a first end and a second end, wherein the first end of the first blade is in closer proximity to the resilient body than the second end of the first blade,wherein the tangential direction is a direction that is tangent to a circumference of the resilient body; contacting an internal wall of the segment of downhole tubing with the first blade; rotating the resilient scraper relative to the drill string within the segment of downhole tubing; and deflecting the first blade against the segment of downhole tubing such that the second end of the first blade is deflected toward the center of the resilient body. |
