There'd be a hard battle to beat the carb cleaner, especially the stuff getting banned because of hazardous chemicals to the earth.
I have a small bottle of Yamaha Carb Cleaner in my basement that I don't even dare to open anymore.
Here in Holland we have quite some cases of military that have developped serious diseases after they had cleaned firearms with benzeenrich cleaners like PX-10. Some stuff is toxic beyond imagination. Many fail to understand this.
