In past years, I have experimented with numerous ways to clean my tubes, both in and out of the water. These include acid washing or pressure washing (on the trailer), manual scrubbing or power scrubbing (in the water).
Currently the best 'in water' scrubber that I have used is the Black and Decker Scumbuster Xtreme. It is discontinued but still available. Rechargeable and fully submersible. It still takes some work to do the job.
Here's a listing for it https://www.amazon.com/gp/product/B000V ... UTF8&psc=1. I usually put onto a beach to use it so that I have some leverage.
I was wondering if anyone has found anything better? I looked at a nice 12VDC scrubber that has a long cord but was spendy at around $200. There also was an Australian 'wand' thingy that manually did a single tube from the dock. I contacted the guy and he said it was only good for round tubes without strakes, so no go there either.
I have been working on an invention for this over the last couple of years with disastrous results during testing
Surely someone has a solution?
