Cleaning questions

[Jim4475]

Hello all, I just bought a house that has a Strong Spa (Barcelona, I think).  It has been sitting for a while and needs to be scrubbed out.  I bought the jet flush but there is slight mold around the actual jets and I wasn't sure what is a safe cleaner to use.  Can I use any house hold cleaners for the initial cleaning of the actual tub itself? The spa is drained except for about 6" or in the bottom. The previous owner stated to just fill the spa and add the chemicals and it will take care of itself, I'm not real comfortable with that, I would really like to clean it prior to my families first time using it.
Thanks

 Good old bleach and water will work, I like baking soda myself..      Either way once you add chlorine or bromine to the spa I wouldn't worry about mold issues under the water.

I'm a big proponent of using distilled white vinegar to clean spas.  It leaves no residue and does an amazing job.  I mix it 50/50 with water.  Maybe a little heavier on the vinegar for heavy duty stuff.  When used with baking soda, you get a nice scrubbing action.  Works great, is inexpensive, and environmentally friendly.

The first thing I would do is add a cup or so of chlorox bleach to the remaining 6 inches of water.  Agitate or mix this, and then drain the rest out.  Then I would clean as per the above posters suggestions.
