Dryer Takes Too Long, Cleaned out Vent. What next?
If you did everything Jim did &amp; got the same dump &amp; blow-out, then that was an improvement. But, that method doesn't scrub or peel anything off. It just makes a small hole in the center to leave the built-up sides to collapse &amp; fall inward to clog up again. Keep trying the blower periodically &amp; shake &amp; pound on the pipe wherever you can. Otherwise, use a vacuum at both ends or a vacuum in conjunction of an extendable dryer vent brush.
