Get the gauze ready and place it within reach of your right hand when you are ready to rub them down.
Take a beach towel or a blanket and roll him up like a burrito.
Lay him on top of a dresser or changing table that is sturdy. He's going to fight so it can't be flimsy.
Then hold his head in the crook of your left arm, use your hand to hold his head still using your arm, left hand, and chest. Use your right hand to pick up the med covered gauze.
You can use your left hand to help your right hand open his mouth. Then you can slip the gauze in and wipe. Make sure it's fixed so that it can't slip off while inside his mouth. You need to be able to pull it out quickly if he gets really really stressed out and starts choking on snot from crying.

I used this method to use the snot sucker on him. I loved getting the goo out. Every time I used the snot sucker I'd pull out tons of green and yellow goo. He would always feel better within a little while.
Also we only used bleach water on all the toys, for electronic stuff we misted it and let it air dry. Wiping stuff dry is so nasty, you have no idea!!!!
Just google bleach water recipe to get the exact ratio. I think it's 2 tablespoons bleach to a quart of water but then it might be a gallon of water. I know the 2 tablespoons per gallon is right ratio for rinsing dishes.
