Product review (3 stars): These fit and work great, but they are annoying to keep clean
These fit and work great, but they are annoying to keep clean.  You cannot simply wipe them.  The silicone material is sticky so solids get firmly attached and you have to run them under hot water with soap to really get the shmutz off. I downgraded them just now to 3 stars, because they have spent the last few days in the pantry because I couldn't be bothered.  I'm already obsessed with cleaning my ceramic cooktop because my last one shattered.
