Cleanup
If you are using water-soluble materials, use warm suds
to clean the spray device. If you are using solvent-
based spray, use a suitable solvent for cleaning, with a
ash point of over 21°C.
Do not use solvents for water-soluble materials, as the
mixture will turn into a gel-type substance which is
dicult to remove.
Figure 16 - Short Term Cleanup
Only follow these instructions when using water-
soluble materials. If you are using solvent-based spray,
follow the Cleanup and Long-Term Storage steps.
