My very DH is preparing to seal our deck. We will need to clean the
deck before applying the sealant. We plan to clean the deck with
bleach. My plan is to
water the plants surrounding the deck
cover the plants w/ a clear plastic tarp,
clean the deck with bleach,
seal the deck,
remove the tarp and re-water the plants to dilute any bleach which may
have seeped into the soil or found its way to the plants.
Has anyone cleaned a deck before with plants nearby? Will the steps
listed above suffice to protect the plants? Should I use a different
cleaner and will that be effective? The deck isn't particularly moldy
or dirty, but we want it as clean as possible b/f sealing.
Thanks in advance!
Plain water will clean it just as well as bleach. If the deck has never
been sealed before, the effect of using bleach on it will lighten the
color more than clean it. If you have some moldy spots, and you're
planning on using bleach because of that, I'd suggest changing the
conditions that lead to the mold growing instead.
Unless you can accomplish this in a very short period of time on a cool,
cloudy day, you may cook the plants.
A power washer with plain water would be best. If you need to loosen
ground in dirt, trisodium-phosphate (TSP) is the usual cleaner of
choice, not bleach. (Make sure you read the directions first. Really.)
Not very good idea to use bleach on a wooden deck. Some of the deck cleaners on
the market now are very "plant friendly". Just wet down the foliage before
cleaning the deck and then spray the foliage again once finished. We've never
lost a plant yet, and the deck looks great. Here is a good online resource
which you might find helpful...
