Warped control vinyl can definitely cause issues with backspins, cueing, and overall performance, but using an iron directly is risky as it can permanently damage the grooves and the encoded timecode. A safer method many DJs use is the “weight and warm” technique: place the vinyl between two clean, flat surfaces with a towel or cloth in between, then leave it in a warm (not hot) area or under a gentle heat source like sunlight for a short period to help it flatten slowly. Some also use specialized vinyl flattening presses available online. Keep in mind, aggressive heat or uneven pressure can ruin the record, so caution is key.
