There are many DIY hacks to solve the problem. One option is to use a hairdryer to dry out the condensation between the window panes. Although this is a cost-effective and quick solution but it's not recommended because it could cause damage to the window seal in the future.

Another option is to drill tiny holes in the window frames, draining excess moisture with a special kit, and sealing the openings with clear cement. This is fairly inexpensive but isn't as effective. It may also need to be repeated often. This method is risky and should only be performed by experts.
