When I was in India I made myself this amazing heavy cotton hammock , It has served me very well , but when I came back home I forget it in a moist place. Now is is still strong but it is covered with black dots of mold , I already put it in the sun and it took the living mold off , but it left black dots.
How can I take it off without hurting the fabric ( after all it is a hammock and it supposed to be strong ) , and without leaving the black color , should I use bleach ?
