How do you fix a slow leak in a rubber tube?

Answer 1

The best way to find the leak is to put some soapy water on the tube and look for the bubbles. The best way to fix the leak, assuming that it is a tire innertube is to purchase an innertube repair kit. You can get the kit from any bicycle shop or Walmart or kmart. The instructions are on the package and are easy to follow. Inner tubes are not that expensive. You might want to replace the tube. I would still suggest buying a patch kit so you arent going down a river and get left flat.
