I plan to haul my 30 ft powerboat to clean the many layers of old bottom

strippers available, but all apparently require a lot of very messy work.
I have heard about a process called soda blasting, which is similar to sand
blasting, but they use baking soda. It is supposed to be environmentally
friendly, and doesn't harm the gelcoat. (presumably, if done correctly).


Can't comment on soda blasting, but can on CO2 pellets which is a
technique used by tank cleaners in oil refineries.

Definitely expensive, requires extensive training and does a great job.

I would not expect soda cleaning to be a DIY process, but I could be wrong.
