    Just about every machine I've ever had has mylar protectors on it somewhere that are outlined in black from gunk getting up under the edges. I've tried hand cleaner, novus, soap, simple green... and had 0 luck. I am tempted to go after it with some dental picks. How do you guys fix this?

    I've had success using a tiny bit of denatured alcohol and lightly scraping with toothpicks - pushing at the grime from an angle with the tip while being careful not to scratch or go under mylar. Again.. very lightly.

    Looking forward to hearing other methods.

    Try Novus 2. Typically used for light scratch removal and should work just fine.

    Rubbing alcohol will get it with enough scrubbing. It will come back sooner than later though.

    I use a different approach.... two razor blades. The first one I slide horizontally under the edge of the Mylar just enough to get under the lip. The second one I use to cut the Mylar using the first blade as a cutting surface. After its cut, I stick it back down.

    Sounds efficient enough; I've got to try this

    Take it off, clean the playfield, put a new one back on. As long as there's no insert below the mylar, there's almost no risk using the freeze method.

    The problem is the black stuff is dirt, rubber particles and other debris that is stuck to the adhesive on the underside of the mylar.
    Yes, you can get in there and remove it but in the process you're also removing some of the adhesive from the mylar at the same time.
    It will make it look better temporarily, but will eventually come back and come back further underneath the mylar where there is more adhesive since in the cleaning process you removed the adhesive nearest the edge.

    Just take it off and don't put mylar back on. If you clean and wax the playfield regularly, there's no need for it.
