Just using that magical super strength Oven Pride cleaner where you put the racks in a bag with the solution. It says to put the remaining cleaner inside the oven. I've done this without realising there's a line of holes down each side of the bottom of the oven and some of the cleaner has gone down there 
There's no way I can access inside the holes to clean it out. Have a royally fucked my oven up? The stuff has so many toxic warnings on it that I'm sure if I use my oven once it's cleaned, it will just poison us all.
Help! It's a gas oven by the way...
