Citrusolv and Simple Green are solvents. Simple Green contains glycol ethers. Citrus degreasers (including the Park Tool brand, which according to its MSDS is one of the less toxic ones out there) contain terpenes and/or pentenes. Gloves (and respirators) are definitely a good idea, but it's important to remember that most gloves, especially disposable ones, are penetrated by these toxins in a short amount of time.
