According to the manufacturer, they now have a solution for
unclogging the spray cans. You can contact them.

As to spraying in another manner, as I too have tried, the
unfortunate problem with the Wei T'o solution is that any moisture
will cause an eventual clog. I am guessing that simply opening the
bottle and transferring it to another container is where many of our
troubles originate. The best way/the most economical way to use the
Wei T'o solution is in the four gallon "Soft Spray" cylinders.
Although there are some additional costs for the spray gun, it is
far better than the spray cans.

I might also say that we have sprayed many, many cylinders of "Soft
Spray" without a clog. At the end of the day, we would clean the
system with alcohol, then vinegar, then alcohol again. We did not
use the "Cleaning Solution" as supplied by the manufacturer. When
cylinders were changed, we would purge the lines of any air to
reduce the possible source of moisture that might cause a clog.

Additionally, I believe, that the spray gun should have a second
valve that would permit cleaning the tip if it should become
clogged. I investigated this idea a number of years ago, but did not
follow through. Maybe the manufacturer has a better system now.
