antimicrobial surface

[fatman]

Is it true that the antimicrobial effects of a Microban surface do not work when under water?  Does the antimicrobial effect work only when the surface is exposed to air?

The concept and the product which uses "microban" protects the product by inhibiting and preventing the growth of bacteria on microban treated products.  

There is no active ingredient in "microban" that has any meaningful benefit to the consumer that attacks or kills bacteria.

It protects the product, not the consumer.

Microban works on the surface out or under water.  It will not affect the bacteria count in the water, just on the surface.  The only two benefits I can think of is possible a waterline that has not been cleaned for some time and bacteria etches into acrylic making it extremely hard to clean.  Maybe some of you have seen that permanent waterline after awhile, or sitting on the edge of your spa without clothes on.

I've only ever devoloped a scum line on the tub back when I was a newbie, but even with the textured surface, it is always easy to clean.   I've never owned a tub without it, so I have no basis for comparison.

Yes.  Most permanent stains have been on swirl acrylics, not granites.

[J._McD]

High gloss acrylic with a marble finish or matte finish quarite acrylic are both acrylic.  The pebble texture simply has a different "melt" temperature that creates the matte finish when being vacuume formed.  

The water line is more apparent in "high gloss" acrylics than the matte finish and both will accumulate oils and minerals at the water line without good skimming action from the filter.  

City water is different than well water which will have more mineral matter such as calcium, lime, copper, iron etc. that can or will etch or adhere to either acrylic surface.
