Sometimes the best business ideas begin with an ordinary problem everyone else has learned to tolerate.

For Linda Stanfield and her husband, Chris, that problem was the toilet.

After more than four decades in the plumbing business, they repeatedly saw customers looking for an easier way to keep toilets clean.

That frustration eventually led to Happy Toilet Cleaner.

In this episode, Linda shares the invention story, the early prototypes, what decades in plumbing taught them about the problem, and how two experienced business owners unexpectedly became consumer-product inventors.
