So I sit at my computer after spending 8 hours giving my house a thorough scrub down.  

You can register with the Do Not Call Registry and scrub these numbers off your list. 

BP Team,

I have a few lists purchased over the last few months that I have been sending direct mail pieces to. I have purchased from the same company each time with the same parameters each time.

What is the simples...

@Wilson Strozier most dialers automatically or have an option to auto-filter out DNC, if you are dialing manually there are DNC list scrubbing services online

The MLS databases that these entities are provided get scrubbed a bit, (some information is removed) and then these entities can provide the database to consumers in their own framework.

I personally don't think people will scrub over your website like that.

Most good auto dialers scrub numbers against the do not call registry, so no laws have been broken.

What I did in one apartment that really helped was to dismantle the bseboard heating elements if you have them, and spray them with an odo ban solution, then scrub as best you can, then respray with bleach.

We just run Shur Scrub, I can't afford 200 or Promar :)

I can put down kitty litter to soak up the majority on top then scrub it with purple grease cleaner and finally power wash it.
