Using chlorine bleach in sprayer

Married2Allis · Mar 14, 2015

I'm looking to replace my old sprayer with a small Northstar or TSC 2.2gpm 12 volt one, mostly for spraying weeds with 2-4D. I don't expect it to last forever, but I'd like to get away with spraying mildew once in a while with chlorine. I was going to use 50/50 chlorine bleach for a few minutes, then flush it immediately with clear water.

Has anybody trashed their sprayer doing this?

I use bleach up to 50/50 mix with water in my pump up sprayers all the time. I would use it in an electric pump sprayer too if I had one. I don't leave it sitting in there even for a day. I suspect bleach of deteriorating rubber valves in one when it stayed in there for weeks. And it would rust steel if there are any steel parts--but it doesn't do it in an instant. Flush it out perhaps twice as the first will remove most bleach and the last rinse should take the remainder out. Make sure to pump plenty through the hose.

I use chlorine bleach all the time to kill
Glyphosate and 2 4D. Used to clean out my row
machine that way also. Just be careful if you have
used a Nitrogen right before hand. The bleach and
ammonia don't play well together and create
poisonous gasses.

Be careful with bleach. My brother used it with a power washer years ago to clean a farrowing house and crates and burned his eyes pretty bad. I am sure there was inadequate ventilation.

I had black and white mold in the basement. I sprayed straight
bleach with my plastic sprayer, maybe every 3 months or so in
the spring through fall months. The mold was really bad.

If you are looking to kill mildew outside on siding or a deck or concrete try a product called "Wet it and Forget it". works real good on mildew or mold on siding or decking and concrete I put it on with a garden sprayer and forget it. One of those rare products that actually work an advertized. I have no experience with chlorine in a sprayer. Available at most big box stores.

Thanks for all the replies, good to know that the sprayers will handle chlorine ok if you just clean them properly. And also I may try the wetit-n-forget-it because I hate to mess with bleach. My north facing roofs all seem to get mildew'd by the end of summer, for some reason lots of moisture in the air here in the mountains near Harper's Ferry WV.
