Get a counter brush to use  when you install and run it down the side of the plank to get debris out of the locking system.If you have a Menard's in that area see if they have the Evolve plank.

Then it should come off easily with a toilet brush. 2) I would go with the home depot route. 

@Ross BernardHey Ross, There are brushes made to clean out the dryer vent about 3 feet long at most home centers and hardware stores...... but it sound like you have a longer run through the roof instead of outside the wall behind the dryer.Is the exhaust pipe flimsy flexible pipe or is it hard metal duct pipe?

So, you guys know that I never touch a hammer or a brush - I've been vocal about that throughout the years.

I contacted the bank who holds the current loan and he brushed me off, saying they don't make loans on property, only does 3-5 yr loans, that I need a Life Company for a permanent loan; and that he is not a non recourse lender, they need a guarantor, or individual.

It will be a big brush up on things. 

After one of my biggest set backs in my career, I decided to get brush myself off and get back on the horse.

It seems like as1 of the sources rent-o-meter maybe good for checking a very broad brush middle of the road analysis for rental amount.

Not the best outcome but at least you brushed yourself off and are back on the horse.Good luck to you.
