<b>HOW TO USE</b></br>Fully insert and remove the console cleaner several times. (Do not use with liquid or store in the console.)</br></br><b>SYSTEM COMPATIBILITY</b></br>This unit is compatible with NES, Retro-Bit, Retron, etc.</br></br><b>HOW MANY TIMES IT CAN BE USED</b></br>The console cleaner can be used over and over. The best practice is to clean it after use using a 1UPcard. Moisten the 1UPcard with WATER only. (Do not use solvents including isopropyl (rubbing) alcohol on your console cleaner. Solvents will cause premature wear.) Using the 1UPcard on the cleaning material will help remove grime and extend the life of the console cleaner, but it won't get rid of all of it. Even though there is still visible corrosion on the cleaner, it will continue to clean and buff the pin connector. </br></br><b>HOW IT WORKS</b></br>The Console Cleaner uses a micro-abrasive material. It will remove corrosion from the contacts but not any metal. </br></br><b>ADDITIONAL INFO</b></br> A clean console is just as important as clean games. If your pin connector located inside your console is dirty, grimy, or corroded, use this before inserting games. This console cleaner is brand new made from all new parts. Assembled in the USA from domestic and foreign components. </br></br><b>DID YOU KNOW</b></br> We are an American company and we love retrogaming!
