Hi
I know there are few BBQ experts on here so hoping someone can help. Recently bought a gas BBQ which has a removal fat tray. The manual and some of the videos I've seen on-line talk about putting some fat absorption granules or other material into the tray.

All I've managed to find is things like tray liners which isn't what I was after. The stuff I was after looks like cat litter and can be left in there most of the season and is changed periodically, have also heard of sand been used. Is there anything that people have used, could recommend etc?

Thanks
