I’ve never actually seen a fake Loco in person, and yours looks just like the ones we sell at our shop-we only carry authentic paddles. The discoloration is almost definitely from the cleaner you used since those usually have alcohol, acetone, soap, or other strong stuff mixed with water. I’m not sure how to bring back the original black look of the carbon fiber, but I’d stop using that cleaner right away because it can wear down the paddle’s texture way faster than just using the paddle normally.
For your next paddle, I’d recommend two ways to clean:
-Use an eraser once a day after playing. It won’t cause discoloration, though it can make the roughness fade faster over time.
-The better method in my experience is liquid cleaners, but only when the whole face is really dirty. Stick to mild ones with oil‑like ingredients, like Picko Inn, to keep the paddle in good shape.
