My mother gave me a used Featherlite 3 horse slant load for Christmas. I love it but the dressing room smells very moldy, It is very bad now because of the mild and damp weather we are having. It will be horrible in July. The tack area doesn't leak but there is an ac/heater in the top. Any ideas on how to get rid of the smell and or mold without replacing all of the carpeting? If even replacing the indoor/outdoor carpet will even get rid of the smell.
