Liquid Rescue 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. 
We always offer our anytime 100% refund if you are less than delighted with Liquid Rescue, so please consider trying it!
