Reader Question: How to Correct the Bad Pressure Wash Job

Written by on July 12, 2015 in Member Questions with 0 Comments


I have a ipe deck that was installed 9 years ago with streaks where someone pressure washed it poorly in the past and also variation in color where a tinted oil was applied at some point. Do you think the best course of action at this point is to pressure wash the whole deck with a cleaning agent (which do you recommend) or use a rotary floor sander and start over. I worry that pressure washing will leave it uneven with streak marks.

Thanks for your help.



Hi Robert,

This is a common issue. We see it a lot where Do it Yourselfers undertake washing a deck, with the best intentions but not the best information or equipment. The biggest mistake people make is that they don’t use the right cleaner (soap mix) for the situation. As a result, cleaning the deck is really difficult, so the person becomes quickly frustrated and uses straight water pressure to try to clean the deck. This is how striping occurs, and it ends up just looking like a bad pressure wash job. Usually, people give up about half way through this exercise, because they are literally going inches at a time, and the results are very mixed.
