The jug is a concentrate, make a solution with water and use with a rag or sponge. I haven't used the ready-to-use spray shown on the site. I did spray gallons of solution from pump sprayer in my sister-in-law's basement .

I had a '76 Westfalia, it took the mold off the tent canvas and interior. Only trouble is now everytime I smell that stuff I get a Grateful Dead flashback...
