Got a bit of tea colored hull stain from the LOTO Shoot Out that I would like gone. Any recommendations of a hull cleaner that wont harm/discolor my aluminum Myco trailer? The Works toilet cleaner?? -Been using On& Off for years on my little boats but I'm concerned about screwing up the trailer finish.

Kurt - I would put on a heavy coat of paste wax on the trailer and not buff it out until you clean the hull. This way you are safe.

I would keep using what you have been using. Do a section at a time and cover the trailer with plastic sheet or shower curtain as you go.

I'm told Bio Clean will not hurt the trailer, but having tried it yet.

I use Slimey Grimey and have never had a problem with my aluminum trailer.

Power one!! Spray on hose off, does not get any easier.

Kurt to be on the safe side I'd still cover the trailer as much as you can, if the cleaners got any strong caustic or acid in it its going to smoke the trailer, I know on/off is an acid.. I'd also make the trailer wet first before you do any cleaning or covering it up that way if you do get anything on it your not going on dry aluminum, the little bit of water my dilute the cleaner....

Power one turned my trailer white in spots. Best i have found is FSR its a cleaner suspended in a blue gel. Sticks to hull an doesnt get all over. Use on long handle soft brush on dry hull let it work and rinse off. Call me if you have any questions.

What would a local marina charge to put it on a rack?

Bio-Kleen should not hurt the trailer.We used it while the boat was on the lift and it worked well cutting the yellow stain.
