I wouldn't use them, you'll just wreck your immune system whilst being over cleanly, poisoning yourself with all the chemicals you eat off said sparkling surface. Not a great idea to let animals lick food surfaces or your mouth however washing things in a dishwasher is perfectly healthy we don't need everything sterilising all the time.
I have five dogs, I'm never ill, neither are any of my doggy friends, usually our friends who catch everything going are the Dettol mob.
