Odor Control/mold stained


Hi Martin,

I know this is not directly related to odor, but it is to humidity/mold. I added some sand to my punching bag, and it seems that the sand was wet. The canvas became stained green like with mold How can I fix that? Is there a way to get rid of the mold and the stains preferably w/o having to get all the sand out?

Thanks in advance,


Sorry for the long delay. I just found the inquiry.

I have products that will remove the mold from the outside of the bag, but as long as there is a source of water inside the bag the mold will continue to return. Additionally, there was probably viable mold spores in the sand you added and now the other sand is contaminated.

I am familiar with most aspects of odor control and removal. I have written an extensive website addressing odor control and elimination (http://www.odorxit.com). On the front page is an extensive odor wizard that takes the kind of odor and where the odor is located into consideration when proposing an answer to controlling the odor.


I have had pets since 1962 and have had rental property since 1992. I also have a line of odor control products also on the OdorXit web site since 1999
