If you notice visible stains inside your Philips grill, please read about it here.
Over time, stains become visible on the inner walls and the inner side of the protection glass of your grill: don't worry, this is normal.
This is not harmful in any way, even when all inner parts get very hot during grilling. It also does not affect the function of your grill.
Please continue cleaning your Philips grill according to the cleaning instructions and you can continue to use it without any hygienic or health concerns.
