The product worked great. It took some elbow grease but after wasting money on so manay other cleaners I was satisfied it worked as adverstised

I had black streeks on the outside painted rails of my pontoon and it was the only product that would remove it. Be careful around any color decals, it did remove some of the color. I avoided the decals and used a wax on them to remove the streeks. I would have given it five stars except for the problem with the decals and labor effort involved.

Used this on a horse trailer and it worked just great. Used it with gloves the first times and then it seemed fine without. Don't forget to use gloves, it will eat your fingers up! My trailer now looks brand new. I got 1 gallon but used less than 1/2 on a 2 horse with dressing room.

I used it on a section of our Aqua Patio pontoon and than asked my wife to see if she could tell the difference. She immediately pointed out exactly where I started and where I stopped cleaning with BioKleen. Need I say more.

It is the best product I have ever used on my boat. I sprayed it on and instantly the streaks were gone. I just wish I would have known about it when we had our RV.

<p>My coach is 14 years old with a gel-coat finish, I had the coach detailed and brought the finish back to new. with three coats of wax, I was looking for a product that didn't require washing and re-waxing the surface and was easy to use. I was so disappointed in this product that I immediately went out and ordered a gallon size refill for the spray bottle. The product as advertised and is easy to use.</p>
