CortJstr is right; in many 'culinary' stores you can buy a small rectangle of stainless steel which you 'wash' your hands with and no smell. But anything stainless steel will do, so don't spend money on some handy-looking 'device'. A butter knife made of stainless will accomplish the same thing.
In reply to the Botulin question, even though it is Saturday I put on my official US Centers for Disease Control ID on my bathrobe and looked for some answers. Here's something like the skinny on the risk:
There have been some undetected outbreaks of botulism related to the consumption of garlic. The problem, mainly, is that the symptoms of botulism are not always well recognized by physicians, and if the victims are spread out, it's hard to notice that there are multiple sufferers. In Canada, there was this story:
Botulism from chopped garlic: delayed recognition of a major outbreak.
St Louis ME, Peck SH, Bowering D, Morgan GB, Blatherwick J, Banerjee S, Kettyls GD, Black WA, Milling ME, Hauschild AH, et al.
Enteric Diseases Branch, Centers for Disease Control, Atlanta, Georgia.
Diagnosis of botulism in two teenaged sisters in Montreal led to the identification of 36 previously unrecognized cases of type B botulism in persons who had eaten at a restaurant in Vancouver, British Columbia, during the preceding 6 weeks. A case-control study implicated a new vehicle for botulism, commercial chopped garlic in soybean oil (P less than 10(-4)). Relatively mild and slowly progressive illness, dispersion of patients over at least eight provinces and states in three countries, and a previously unsuspected vehicle had contributed to prolonged misdiagnoses, including myasthenia gravis (six patients), psychiatric disorders (four), stroke (three), and others. Ethnic background influenced severity of illness: 60% of Chinese patients but only 4% of others needed mechanical ventilation (P less than 10(-3]. Trypsinization of serum was needed to show toxemia in one patient. Electromyography results with high-frequency repetitive stimulation corroborated the diagnosis of botulism up to 2 months after onset. Although botulism is a life-threatening disease, misdiagnosis may be common and large outbreaks can escape recognition completely.

Now, before you all stop eating garlic permanently there are a few more pieces of important information.
1) The Bug: Clostridium botulinum is the name of a group of bacteria commonly found in soil. These rod-shaped organisms grow best in low oxygen conditions. The bacteria form spores which allow them to survive in a dormant state until exposed to conditions that can support their growth. There are seven types of botulism toxin designated by the letters A through G; only types A, B, E and F cause illness in humans. C. botulinum can be processed with garlic all the way through the manufacturing process.
2) The Environment: This is an Anaerobic bug; that is, it requires an oxygen-free environment. Oxygen kills it. This is why garlic packed in oil is a good environment, but packed in water is less so.
3) All Bacteria require certain conditions in order to live: Temperature, osmotic differential, Ph, level of oxygen and moisture are all continuums across which different organisms live and die. There may be others but I'm too lazy to go find the textbook. Anyhow, the point is that these are the kinds of conditions you address when saving/preserving food. It's easy to see why our forefathers ate Jerky, Salt Pork, honey. hardtack, dried fruits and beans, jams/jellies/preserves and such things as much as they did - they had no refigeration. Salting or sugaring food down, pickling, canning/jarring, and other methods of preservation address one or more of these germ needs and makes food preservation possible in the absence of refrigeration.
In the case of Botulism: It's not the germs that kill you, it's the poisonous by-product of their respiration. The toxin is destroyed by heat; boiling canned foods for a few minutes will render it safe in terms of botulism. So should frying or sauteeing over the course of 5-10 minutes. Refrigeration of the product should prevent it from growing and secreting toxin also, but will not affect toxins already secreted. Using fresh is no hazard since fresh garlic is very unlikely to have been in an anaerobic environment.
Sorry about the voluminous post.
