Sevin is pretty low toxicity and the chemical has probably largely
broken down in a months exposure to sunlight, but I wouldn't want to
eat anything that had "rich deposits" of residue without making sure
it was washed well. If reasonably high pressure from a hose won't
remove it, you may have to pick the grapes and then do a hand scrub in
water to get it all off. Rinse well after that and you should be
fine.
