@Ben M Cast iron or porcelain on metal tubs dont really stain...the surface can get damaged by abrasive cleaners or have heavy hard water deposits.

What is the best roof cleaner product or product to remove dark stains on a middle aged roof?

Ray Kroc built a whole empire out of realizing he could sell cheap crappy hamburgers as long as the johns in his hamburger joints were cleaner than the next guy's.

If you're leaving a software engineering job to learn how to be a Kirby vacuum cleaner salesman, with thoughts that you'll open your own Kirby business, I'd say don't touch anything and learn to be as frugal as possible.

Cleaners come at noon and use the keys in the lockox and are done by 3pm. 

.  ;-)  I hire a cleaner now, but still....5) They'll think I'm weird for asking to do this.  

I think the wall units look cleaner but were not sure if they were as effective as the baseboard).On top of that was wondering if you would recommend the hydronic baseboard units or the standard convection heaters.I also noted your in NY are you using these to solely heat a house or as supplemental and do you feel they could adequately provide heat to a house in the NE during the dead of winter.

Cleaners don't show up.

My favorite:  Do you own a vacuum cleaner? 

These are little places (my guess is 600') that do not take long to clean but I could not have cleaners there between every tenant change, deal with tenant questions/issues, etc.
