Hey, sorry, no - I am in Australia. Looking at Spot Shot's site it seems they are one of the products owned by WD-40, so they seem reputable. If using chemicals test in a small area to ensure the colour doesn't leech out like you do with clothes.
I'd use Spot Shot for more stubborn and difficult stains like coffee if you couldn't get to it fast enough, but the basic cleaning products (water, dish soap, vinegar & bicarb, etc) will work fine as they'll dilute before the stain can set in.
Don't tempt your luck with red drinks though.
Oh it definitely is. Also consider having to work in a humid room as you'll be working with a wet carpet too. Not gonna be fun on a hot day unless you have ventilation and air-conditioning.
