Pressure washing and power washing have been the main method of cleaning decks.
The cleaning typically was done prior to staining or
painting to remove dirt, molds, algae and fungus. As professionals
began to specialize in deck cleaning chemicals were added to the
process for a more uniform level of cleaning and to allow the use of
low water pressure rinsing (less wood fiber damage). This process
is done by typically wetting down the deck to prevent the cleaner from
drying to fast than apply the cleaning mix, dwell and rinse. Dwell
time is important. The process is than finalized by spraying the deck
with a wood brightener to balance the ph for preparation of a finish.
This is the main method of professional deck cleaning.
At Carlton Cleans we changed the process by removing the
pressure washer from the process. The main reason we removed the use
of a pressure washer is even at low pressure with the use of chemical
cleaners minor damage to wood fibers can still occur and the chemical
strength generally has to be on the strong side to be effective.
Carlton Cleans uses scrub brushing in the place of a pressure washer.
We use a low pressure chemical sprayer to apply our deck cleaning mix
and hand scrub the entire deck. The process is finalized by applying
a wood brightener. The lower chemical ratio is better for the
environment and the technicians doing the work and still effective
because of the scrub brushing process. The scrub brushing is gentle
on the wood and is a very effective cleaning method. Of course the
process of scrub brushing is more time consuming than pressure
washing and high chemical ratio use. Carlton Cleans also applies all finishes by hand.
