If you've ever microwaved tomato sauce in a regular old plastic container, you know how much it sucks:  Tomato sauce stains everything.  Permanently.  What a jerk. 

Miraculously, Wendy and I received Rubbermaid Stain Shield plastic containers (don't call them Tupperware; that's a brand name) for our wedding.  It actually wasn't that miraculous; we asked for them.  But little did we know they would change our lives forever.  As I sit here writing this, I'm eating pasta with spaghetti sauce out of a Stain Shield container that I just microwaved.  All I can do is marvel at how totally awesome this thing is.  Awesome enough to be written about in Popular Mechanics.  Stain Shield containers completely resist stains.  That's because they're made from a different material than most plastic containers.  Not only do they resist stains, but they're also dishwasher safe and freezer safe. 

If you've ever flipped out because you can't clean the stains out of your plastic containers, invest in some Stain Shield.  You'll never flip out again.
