I'm not an expert, but the symptoms remind me of a problem I had. 

When I first got mine, during my first water fill, I had developed a rash on the underside of my arms and my neck.  It was because I hadn't cleaned the edges of the hot tub.  I used a hyper-chlorine water mixture and wiped the edges above the waterline and underside of the cover down and I do that now every week or two and no more problems.

What would folks advise to clean the top & outside of the tub with ... How can I make a hypo solution ?? ... Could I just use bleach from the washroom ( Clorox ) .

Yep. You can use laundry bleach, just be sure to use only regular bleach. Don't use anything with scents, splashless bleach, or anything like that. Those things can screw up your tub water. The bleach bottle should have directions for making a disinfecting solution. Something like 1 cup bleach to 1 gallon water, but check the bottle in case your bleach is stronger or weaker than the normal 6% bleach.

I use about 2 ounce of Clorox 6% bleach per 1/2 gallon of water and wear a plastic scrubber glove made for cleaning hot tubs (it's basically a glove with a non abrasive scouring pad attached).  I just dip the glove in the mixture, rub it on the tub edge all around and underside of the lid, then when finished I hose it down and add any water I need to makeup in the tub (since it is cold you could just rinse off the chlorine mixture with a bucket of warm water and a clean sponge).  Any left over chlorine mixture I dump some on my plastic steps and add the rest to my foot-wash water pan to sanitize them.
