Now that Ziggy has already cleaned the bottom, I will chime on the pressure wash. Yes, some depends on the pressure washer, but a great deal more depends on the condition/age of the inflatable
. the older the glue is, the more vulnerable it is. I've pressure washed plenty of them.
I came up with a neat trick to keep bottom growth off.
Blue tarp, pool "noodles" and hot glue gun to build myself a bottom liner. Just add a little chlorine bleach. Real easy and way cheap
. I probably spent 20 min and $15 building it.The bottom liner does not have to sink at all. Just very shallow sea water
under the dink that I added the bleach to. Worked for months very well for me and those on my old dock
who copied it. I gave it away when I dropped the dock
lines. It went right back to work in another slip.
Part of the trouble of cleaning
any dingy bottom (In the water) is that the thing wants to move away from any pressure you put on it. Hard to make it hold still for you. Better to not grow anything than try and clean it off.
Not living in a slip anymore, I do as Zee says. Build a harness and lift
it just barely out of the water
. High enough to be a problem to thieves as well as critters.
