I am looking for some help guidance on the pressure washing of my IPE deck. The deck has not been cleaned for two years and is grey. I have a Briggs & Stratton 2900PSI Washer. What is the recommended setting/tips for the job. Also I am looking for a suggestion on what chemicals to use in the cleaning process. We are in the Dominican Republic so there are no USA made products available so we probably need a formula for a home made cleaner. Any help would be appreciated
