Are you checking the PH of your chemical solution before spraying the chemicals?  Here is a link to a previous NAFEX post on chemical PH:  


You can also check to see if the chemical you are using is available as a flowable liquid which is much better than powders.  You can use the http://www.cdms.net/LabelsMsds/LMDefault.aspx database to search for availability.

Long time no see, Tom!
May I suggest that some pwders do not dissolve well...
Settling can be an issue as these powders may be impure,
and have some non-dissolvables.

But off the top, I'd say try a blender.  Then allow this
to settle in a clear tall drinking glass (one time only,)
to test THAT powder for settleables. If any of these are
toxic, dedicate a blender to that use. Plastic bodies/jars
are susceptable to aborbtion and some cross contamination,
but are a few bucks or GoodWill. Separate gaskets will be
needed, and why not use your old blade, and get a new one
for margaritas... Of course, lacking these, you could
use a disposable coffee filter.

Watch out for plastic absorption if you use this filter
frame for coffee too. Melita's are $5. A plastic strainer
and a napkin or paper towel even, for today.

Grow ON!

Hello All,

I have a question for all small, pump sprayer users.

I have two one gallon, pump sprayers, and no matter how diligent I am with
rinsing either with water, and water with dish soap after usage, I cannot
get half way through spraying my one gallon of spray, without the darn tip

I premix my powders with warm water in a glass jar, shake them up, then add
that concentrate to sprayer.  I even use reverse osmosis filtered water
thinking that hard water was my issue and I still have tip clogging

Is there a secret to prevent tip clogging in small pump sprayers?  I am
totally frustrated and disgusted with the tip clogging problem at this

I have even filled them with warm soapy water after rinsing and allowed that
to all spray out, and still I get the problems.  Should I use vinegar or
ammonia as a final rinse?
