Whatever changes the sonics the least (or, at least, for the better) and doesn't cost over $100....
If it starts flaking within a month or two, it could be for two reasons that may still impact whatever material headphone pads you use. First, your sweat may really be too acidic; the other reason may be that you are simply putting too many hours on them. Chances are your alternatives might end up still having a relatively short service life because of these, and although they might last a little bit longer than Grados' foam, the cost of the alternate earpads might make them less economical than getting foam pads every two months.
That said people have replaced the earpads on Grados with a lot of pads, including fullsize circumaural pads mounted using an adapter that works similar to a spacer. This is primiarily for comfort, and secondly for isolation: where the spacer adds space on the Grado driver mount but still uses the same Grado or Sennheiser foam pad, using a circumaural pad transfers the pressure away from the earlobes, relieving discomfort as well as sealing up the surrounding area for better bass. Note however that it may change the sound considerably - I've listened to an SR225 with a spacer as well as a longer chamber, and the bass was overwhelming for me. A circumaural pad with the stock chambers might not have the same bloated deep bass, but it might impact how strong and forward the upper bass can be perceived, although it might benefit the lowest bass notes through isolation.
Oh and if you don't have the woodworking tools and skills, these aren't cheap: http://www.headphile.com/page15.html
