You can use any goalkeeper gloves conditioner. I recommend the Keeper balm grip stick. It’s quite useful to restore the grip as well. Keeper balm will make any latex gloves a high-quality gripping gloves. Applying the balm is as easy as pie too. Just grab the plastic, and apply it on the palm of the gloves from top to bottom. Using this kind of grip stick is better than using a spray. It’s because the spray won’t stay long, but this balm will.
