I do have slide toppers on the TT and this does get under there.
Photo of tool: I used a 6' piece of 1/2"od aluminum tube. You can see how it's attached. The flexible paddle is 2" x 3" x 1/8" and can get under the seal, flip over to do the top and the "p". Flip over to do the wipe off in the same manner. It's covered with a 5" x 9" gauze pad and secured with a tie wrap. Works awesome!. EMT might work for the pole, PVC, meh... you need the thing to be ridgid to push-pull back and forth and control it under the seal
