Re: bleaching carpet
hmmm, well I be danged! I diluted about 1 gallon bleach to about 2 gallons of hot water and added a test piece of carpet and guess what happened? It got really clean

No color change at all! must be the synthetic marine fabric has no dye in it to be bleached out. Go figure ,woulda never guessed. Did find a use for a bleach pen though, works great on old white rub rails,makes them look new again .Cheaper and faster than replacing too!
