SWIM has a bottle of GAA he kept at room temp for about 5 months which was originally clear white and now is a yellowish clear; perhaps from oxidation; SWIM's not sure exactly what chemical reaction took place however SWIM is pretty sure it shouldn't be hard to clean up. SWIM was hoping it would be so simple as sticking the GAA in the fridge allowing it to crystallize fully then wash the impurities off of it? SWIM's not sure if this has much of a chance working so SWIM was hoping one of you friendly knowledgable bees out there could help SWIM out on this one. Thanks

I think you might have dropped some metal or metal salt into the acid, discoloring it. I believe distillation (114°C) is the only really good way of making it crystal clear again.
