How to look after non-stick cookware so it lasts?
I'm still happily using a non-stick frying pan that I've had for almost 4 years.

I only use Teflon utensils.

I never use harsh abrasives.

After cooking, I fill it with boiling water, let it soak for a while and then wipe out with paper towels. Most of the time I just give it a quick rinse and it's ready for the next time.

And buy quality - "Quality is remembered long after the price is forgotten".
