BioGuard Stow-Away 1 Qt. | Pool Cover Cleaner

BioGuard Stow-Away cleans and deodorizes pool covers before storage, and it solves a problem most pool owners only discover the hard way: a cover put away dirty can be ruined by the time it comes back out.

The failure mode is folded-together vinyl. A cover stored with organic film, oils, and moisture still on it will bond to itself along the folds over a long off-season. When you unfold it months later, the layers separate unevenly — or don't separate at all — and what comes out is a cover with permanent creases, weakened seams, or torn material. The smell that comes with it is the other half: mildew and decomposing organic matter concentrated inside a tightly folded package for months.

Stow-Away addresses both. It cleans the cover, deodorizes it, and — critically — prevents the material from sticking together when folded, which is why the directions call for squirting it between each fold rather than just washing the surface. It also aids in stain and soil removal and extends the life of most covers.

The feature that saves the most time: covers can be stored wet. Anyone who has tried to fully dry a large solar or winter cover on a fall afternoon knows this is the difference between a one-hour job and waiting for weather. Stow-Away is formulated so a damp cover can go into storage without the mildew and sticking that would normally follow.

It's versatile beyond the cover itself, working on solar covers, pool umbrellas, and other poolside items heading into storage.
