Gas oven - - melted plastic inside

Question

last night when the oven was on and I noticed a smell coming from the oven and it turned out to be a blue plastic lid had fallen down and it has now melted inside the oven - - how do i fix it?

i have been able to remove most of the plastic that is visible - - but what if some of the plastic oozed into the holes on either side of the bottom of the oven? could this cause an issue if I were to turn the oven back on for use? Please advise. Thanks!
