Here you go Stan:
I have both the Frog Mats and the Amazen Q mats and the Q matz are more flexible than the Frog Mats. This makes the Q matz a little easier for me to clean since they can be rolled up tighter to fit into my sinks and washed down, then shaken off to dry the clinging water. I used my Q matz when smoking some uncased snack sticks and the grease rolled off of them and sticking was never an issue with the meat. Then when I went to clean them it was as S2K9K said, most all clinging debris came off with the sink sprayer and the heavier debris just wiped off with very little effort, and then ready for use again. My Q matz I use are trimmed to 22.5 x 22.5 to fit my fridge smoker and
I like using them.
