For example, my business has identified the need for a quality hydraulic dump trailer.

So many newbies don't know how to buy the right property, that it wouldn't matter how good or cheap the contractor was... it's going to hose them.

It looks like a metal, braided flex line, which would be a pressure or supply hose.

For the oil staind I use Dawn dishwashing detergent straight and let it soak for a few days and then hose it off .

It saves you money but you could get hosed of not up to speed on what is going on.

This involves balancing, tipping, chaining, tipping some more, swinging, and lots of careful hydraulic work on the front end loader of the tractor to get the 18 foot pole from horizontal on the ground to vertical chained and strapped to the forks on the front end loader of the tractor. 

If so, he hosed himself and you.  

For example they don't want situations where everyone that has been watching the weather channel and knows the storm track, buys flood coverage at the last possible moment, and the company gets hosed. 

Hydraulic excavators were a tiny niche for very small jobs.

An alternative to the lint brush is to use a wet/dry vacuum and snake the hose down the dryer vent from the inside.
