Use to be big into cleanings and restorations and have actively cleaned my own pairs since doing it for money a few years ago ,I recently picked it up again and was doing a basic pair of af1 Mids for a customer ,after a quick clean on the toe box Bubbles’s appeared ,I’ve never seen this before and have cleaned 100s if not thousands of all kind of air forces ,any advice or comments? TIA
