I have found that the best way to clean a Foreman grill is to do it
immediately, while it is still hot.  I use a wad of paper towels and wipe it
down thoroughly.  After it has cooled, I use a soapy sponge several times
and then rinse it completely with a damp sponge, again several times.  I
found that if I waited until it was cool to do the clean-up, when I tried to
scrape the food remnants, they splattered all over my counter and some of it
was difficult to remove from the grill, even with the scraper that it comes
with.  Hope this helps.

As soon as you are done cooking, leave it plugged in and grab a couple
of paper towels. Run them under the faucet and squeeze the water out,
but not all of it -- you want it dripping a little. Wipe it down with
the damp towels and it will all come right up.

I use my Foreman grill almost every night. I don't see how I could be on
LC without it.

I also don't know which one is best but would like a larger one than
the one I have.  I have a small one with the bun warmer, which I find
worthless.

I clean it the way you are not supposed to but it works great.  I
unplug it, open it, put it in the sink and use the spray nozzle.  I
give it a quick rinse with the spray nozzle then I use a sponge or
scrubbie/brush and some soap, rinse quickly with the spray nozzle
again, tip over to drain, and leave it open to dry.

I have been doing this for 2 years and it still works and looks great.
I use it almost daily and have even used it camping to toast bagels
for my daughter.

Best of luck.

Yup, clean it when its hot.  Use a dish rag you are willing to loose
with water and just wipe off the surface(s).  Works great for me.

I hardly ever ued my George Foreman grill, now I use mine every day -- only
because someone here at ASDLC posted a really, really easy way to clean it.
There's a nifty "trick to it!"

While the grill is still very hot, saturate a few paper towels with cold
water.  Put the wet paper towels on the bottom plate and close the grill.
(It will steam like crazy).  Walk away and eat or do whatever.  After the
grill has completely cooled,  you can now very easily wipe it clean with
clean, dry or damp paper towels.  (The steamy wet towels absorbed and
emulsified  teh worst of the grease, and softened any hard particles).  It
works so well that I couldn't believe it the first time I tried it!   No
scrubbing at all, just wiping.  If you forget and turn off the grill before
doing this, simply plug it in, let it get hot again, then put the wet paper
towels on it, close it, and wait for it to cool.

Make sure you have your little plactic drain pan thingy under the edge or
you'll have a mess as the steam liquifies the grease and it runs out.
