When soft washing you homes exterior walls, roof, driveway or even back patio the aim is to clean the area with no damage to any of the near by landscape including trees, shrubs, grass and flowers that take months and up to years to grow.
There are a few main keys to watch for before tackling the cleaning job.
What are we planning to clean?
What plants should we look out for?
What concentration of chemical should be used enough to kill the mold and mildew but not harm the plants?
How do we water the plants when in the process of cleaning?
In this scenario lets cleaning a two car concrete driveway and sidewalk with a barrier of flowers on each side and grass, The common household exterior cleaning needed in many south florida homes.
As stated before we are cleaning up a driveway and sidewalk with flowers and grass as our surrounding landscape to watch out for. The plants to look out for are the beautiful but sensitive flowers and brittle green grass that can change colors fast when sprayed with chemicals from the soft washing and pressure cleaning. The level of concentration we should use is a lower dilution of chlorine and soap to lift the organics sticking to the concretes pores and pressure cleaning off and because the concrete has many deep pores we recommend leaving a added layer of chemical to kill of any residual bacteria lingering around. When doing this type of cleaning we recommend you to water the landscape after as a final rinse to water down the low concentration of chemical and any dirt that was lifted up on the walls and plant foliage, plus it also helps with the harsh chemical smell that many homeowners find undesirable.
In just about every scenario we only recommend you to water the plants down with water throughout the pressure cleaning process especially when using a higher dosage of chemical and soaps. Using tarps and covering the plants make seem like a good idea at its surface but if the outside temperature is hot then the tarp acts as a convection heater and literally burn the plant. Tarps also hider us from looking at where the chemical is falling down, it make seem like the chemical hits the tarp and thats it problem solved but if we look closer we can see the chemical drip straight down to the plants delicate roots and dry up at the source. With the focus being on the cleaning, all eyes are kept off the chemical going to the root and that means game over for the plant that look years to grow and mature.
