My 15 year old boat has black patches on the indoor outdoor carpet. It

The vinegar ans soda douche' probablytook care of the mold and mildew,
but your carpeting is probably permanently stained. you might check
with someone that sells carpetng or is in the carpet cleaning business
and ask them what they would recomend.

That's about all I can add
