The core group longs here believe and trust the product (and use it regularly). But the newer folks, need to see this to trust that this product works. And you are accomplishing that.
I actually caught my 8 year old daughter the other day cleaning the kitchen counter top with WC. I asked her why, and she said it was because she got fingernail polish on it while painting her nails. Prior to WC I would have been a little upset, but now, I just told her to clean it up and go play. No worries.
I've even cleaned up fingernail polish off my hardwood floors. Try that with acetone.
