Stop in for a cup of coffee

As said 15% vinegar. I got 30% from cleaning aisle in Home Depot and cut in half with water. Not sure how much salt is needed if you go that route.

FYI. This is not a budget solution. More of a way around nasty chemicals. The high test vinegar was like $20 a gallon. I’m pretty sure the Spectracide concentrate I normally get works out to much cheaper.
