I scored some free Kanberra Gel samples thanks, and have had them on the boat now about 1 month. I have 1 of the 4-oz sizes and about 6 little 1-oz sizes on my 41' boat.
When I first got them and opened them up I felt that they put out a strong odor
, but I'm kind of sensitive to odors which is why I was trying them to start with. So I decided to try them on a slower release and on the 4-oz only removed the cover from 3 of the holes in the top of the container; and on the 1-oz I drilled a hole in the top of the little plastic lid. I put the 4-oz in my aft berth where there was just enough of a musky smell to have started my to look at the Kanberra Gel and spread the 1-oz sizes throughout the boat in various locations.
I can detect the scent of the Kanberra Gel if close enough to it and since I put the 4-oz on a shelf right above our heads in the aft berth we have started capping that at night when on the boat. But we only really smell it when in bed
and can not smell it in the room in general otherwise and if I moved it to a different location it probably wouldn't be noticed anymore. I don't really smell any of the little ones unless I put my face down near them or if I open them up all the way and are fairly close.
So did it work? I would say yes. I have not noticed the slight musky smell on the boat overall as before. And I haven't been waking up with that taste in my throat or a clogged up nose like before. We can detect the Kanberra Gel scent when coming to boat after it has been shut up all week, but that quickly goes away once the boat is opened up and I figure that is just the gel working.
It doesn't seem to work it's way into areas that are closed on the boat, like lockers. I opened my liquor cabinet the other that I don't normally open and it is above the bilge
and it was pretty musky and moldy smelling. So I put 1 of the 1-oz containers that I had drilled the hole in the top into the cabinet and the next day the musky smell was gone. Maybe I should move a few of the 1-oz containers to lockers of bilge
So on my boat that doesn't have a big problem to began with I would say the Kanberra Gel works. I will probably buy some when the time comes to replace, which is the true bottom line review.
