Liquid Bearings is the 100%-synthetic lubricant that consistently outperforms all others. It has incredible low and high-temperature performance, which is absolutely necessary for proper typewriter operation, but completely lacking in petroleum-based oils and sprays like silicone. Petroleum oils and lubricant sprays also leave sticky deposits when they evaporate over time. Petro-oil is made up of a mixture of long and short chains of carbon and hydrogen atoms, and under certain conditions the short-chain molecules evaporate, and the unstable molecules oxidize and break down. This leaves a sticky residue which can actually "gum up" the device it was intending to lubricate. Conventional oils also contain impurities such as sulfur, waxes, and unstable hydrocarbons which are left behind as residue deposits. In contrast, Liquid Bearings is made using a process that re-arranges the structure so all the molecules are uniform in size, shape, and weight, an ideal phenomenon which does not occur in nature. Liquid Bearings is also essentially odorless, so your hands and clothes won't smell like oil after using it. It is perfectly safe to begin using Liquid Bearings on your typewriter with no pre-cleaning, even if you have been lubricating it with conventional oils for years. It is fully compatible with all vintage and current oils, and will eventually flush away the residue of the evaporated petro-oil over time. You will instantly notice that your keys, carriage, platen, ribbon spools or typewheels will move more freely and smoother with Liquid Bearings, especially if you have been using petroleum-based oil on them. We always offer our anytime 100% refund if you are ever less than delighted with Liquid Bearings, so please consider trying it!
