Never neglect your siding after those wet Louisiana winters. Just like your roof, it will collect dirt, grime, mold, and mildew from the elements. This can lead to Oxidation, exterior wall breakdown, & a dull/dirty looking home.
This type of cleaning requires a lower PH with gentle rinsing and a shorter dwell time. If your home exterior is Vinyl Siding, Hardie Board or Painted Wood then you’ll want to use a .75 – 1% mix, Brick or Stucco will need a 2-3% mix. If stubborn spots still exist, do not increase your mix, use soapy water and a stiff brush, brush out excess mold and mildew from the surface of the siding. Pressure washing is an option, but we do not recommend, it can be hard on your home’s exterior a cause leaks near windows and anywhere you have a sealant.
