Liquid Rescue is the 100%-synthetic lubricant that consistently outperforms all others. Petroleum oils and lubricant sprays leave sticky deposits when they evaporate over time. In contrast, Liquid Rescue 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 Rescue 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 Rescue 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 Rescue. We always offer our anytime 100% refund if you are less than delighted with Liquid Rescue, so please consider trying it!
