A few habits make every fix more reliable.
Reduce glare while you shoot: place the product in soft window light, avoid lamps directly overhead, block direct light with a white card or a diffusion cloth, switch off the phone flash and try a slightly different angle.
These small steps often save more time than any edit. For glare you cannot avoid, let the model clean it up, and keep the original next to the approved version in the same folder so you can compare or redo it later.
When several people on a team prepare listings, agree on one or two standard notes, such as keeping a soft natural highlight, so every product in the catalog is processed the same way.
Review results at full size on a large screen before upload, because small changes to text or edges are easy to miss on a phone.
Finally, remember that shoppers trust photos that match the item they receive, so treat every cleaned image as a faithful record of the real product, not a new design.
