This is along shot but you never know... Flooring guys had to use a lot of Liquid Nails construction adhesive to install a bull nose edge when putting down new vinyl plank flooring. I had to rip a bunch of 3/16" thick small plywood strips to go under the bull nosing for them. They had to use a lot of construction adhesive to fill the gap and thought they wiped it up what squished out when they pressed it down, but left very visible smears (in the right light refection) when it dried. It was water soluble before it dried, certainly not now. Anybody have any experience on how to clean this off the vinyl planks without damaging the planks? You can only see it when the light hits it right, not obvious the rest of the time. Know this is not a pure woodworking Q, but need any ideas. Randy PS the installers are not returning phone calls....
