I have a 29 year old 50 horse Johnson that was really showing it’s age. The product made it look brand new and this took only 10 minutes. One if the best products i’ve ever used.

<p>We've tried everything to get the black streaks off of our boat with no success, and found biokleen and gave it a shot. Holy cow! This product works just like it says! Spray it on and wipe it off and the streaks are all gone! I totally recommend this product to everyone!</p>

This is the best product for removing streaks I have ever seen! Tried them all and none compare. Easy to use and a pleasure to use.

Snaps made out of cheap metal causes the streaks on the side of our pontoon. Biokleen is the only thing we have used that actually gets them off without it taking all day. I like that it isn't toxic!

The bio keen is fantastic for getting black streaks from your trailer or mobile home. I previously tried everything including wax and it did not work. Thank goodness for biokleen
