Cleaning used spa

[kacrab10]

Just wondering if anyone has recommendations for cleaning and purging new (used) spa. We are purchasing from a family we know but ya never know what goes on!!    What should we do to clean inside and jets before getting in.  Also anyone know what a 2006 Sundance Bahia is comparable to in 2008?  It appears to be a 780 series but can't be sure.

I'd saturate a long haired gerbil with alcohol and make him run through the pipes. Some of the newer spas have over sized plumbing, is which case a small long haired gunnie pig might do a better job.

Or, if you'd rather, a plumbing cleaner such as Swirl Away or Spa System Flush should work sufficiently.

I have to disagree with Doc.  The Gerbil and Guinea Pig should use regular household bleach not alcohol.  And just to ad, I would make sure to do a good heavy shock after the other treatments are complete.

BAAAAHAAAAA , Never thought about the gerbil thats about all they are good for!  I think I'll stick to the swirl away and shock though it might keep me out of trouble with the Pet people!!  Thanks.  and Thanks for the huge morning chuckle.
