Bev, do you use anything special to clean your foams, or just elbow grease?

How often do you replace your foams?

Rory,

I squeeze the living heck out of them in container after container of hot tapwater until they are clean.

I replace them when they start falling apart or when they lose their rectangular shape. Usually they last at least two months, often longer.

Good to know, thanks Bev.
