I've heard the flour thing before...I've got a game waiting for it myself.

The glue is worse then the mylar. Use 91% alcohol +flour and start praying

High Speed is by far the worst mylar glue residue I've ever dealt with. I used a lot of Goo Gone, plastic razor blades to scrape with, and even Magic Eraser used VERY carefully. There is a method out there using flour that I haven't tried yet, maybe that would work too

Soak a few paper towels with Goo Gone (goo gone only, not one of the other things that are similar), let sit on playfield a few minutes. Some type of plastic scraper (cheap credit card type thing). *Gently* scrape it off. Repeat as necessary. When you get to the end, your thumb is the best tool to rub the remaining small bits of glue up into little "boogers". If you aren't sure you got it all, slap a quick coat of wax on it. The spots where glue still exists will be dull because the wax won't stick to it. Just be patient and gentle.

If you suspect the paint will come off, try the flour method. People seem to rave about it here.

I've done goo gone and elbow grease, and it's a PITA to get it all off.. plus it's very abrasive to the field (all that scrubbing).

Who make the best adhesive? 3M, so they also make the best remover.

Brush it on with a tooth brush, and use a credit card to scrape it up or a plastic razor from:

Whoa!

I just had to remove glue from a playfield that had its mylar pulled several years ago and was abandoned that way,uncovered, so old dried glue with dust caked on it. Goo gone and flour did the trick (rubbing it off with those blue "shop" paper towels from pep boys/costco). It was the hardest glue removal I've ever faced but it come up beautifully.

I originally found it at Slacks Auto Parts, but I'm in Georgia. If you get your hands on some, it will become a staple in your workshop.

I have used the white flour + alcohol method, it works great. Pat a thin layer of flour into the residue, then dab your fingers in alcohol and roll up the glue with the flour into balls with your fingers....Repeat until all the residue is removed. Good Luck!

Flour with Goo Gone worked great for me. It still took a little bit of time (TAF), but it was much much faster than Goo Gone alone.

has a lot of Naptha in it that's why. http://www.uline.com/PDF/MS-19595.pdf

I used a rag soaked in Naphtha ( lighter fluid ) , placed it laying on a section of the PF glue for about 5 minutes then removed it and used a plastic scraper to roll up the old adhesive in little balls. It works but is slow going.

Naphtha did not budge the slingshot mylar adhesive and I used the orange / citrus based chemical weapons on those areas.
Don't leave the orange based stuff lay on the PF for an extended period, it will loosen paint.
