sharp pair of tweezers or a needle or a toothpicks should be able to help. tons of instructions on how to do it in this thread, but I will add my 2 cents as a phone tech and say that if it’s a lightening port, you want to keep your tool as vertically in the middle of the port as possible while scraping horizontally. for USBC, keep your tool as close to the walls as possible while avoiding the center “tab”. this is so you don’t scrape the contacts. if you do that, you will need a port replacement (usually 80-100$ on most devices). once you scrape as much as you can out. you can use an old toothbrush or whatever works to brush the port clean with some isopropyl to clean any dirt on the contacts, which will come off easily now that it’s not being supported but the other debris you cleaned out with the tool.
