When to clean your monument – The best time to clean a monument is on
a cloudy day. The clouds will keep the temperature of the monument
lower and will slow the drying of the S/S Biological Solution allowing it
time to work.
Follow the steps for accessing the soundness of the monument. If
the monument is not sound, go to the steps for cleaning an “at risk”
Take a small amount of S/S Biological Solution on a rag or paper
towel and apply it to one of the bottom corners of the monument.
Allow the S/S Biological Solution to dry. Be sure that the S/S
Biological Solution has not damaged the monument in any way by
discolouration or staining. If it does, return the S/S Biological
Solution for a full refund.
Dilute the S/S Biological Solution three parts water to one part S/S
Thoroughly wet the monument with the S/S Biological Solution
mixture. Allow the S/S Biological Solution mixture to soak into the
stone and the biological growth by waiting 2 to 5 minutes. Do not
let the S/S Biological Solution mixture dry. If it begins to dry, apply
more of the S/S Biological Solution mixture.
Using the brush and putty knife, remove the biological growth off
the surface of the monument. You will have to apply more of the
S/S Biological Solution mixture to completely remove the growth.
You may have to repeat this step several times to completely
remove the deposits. Be patient and allow the S/S Biological
Solution mixture to do its work.
Once all the deposits have been cleaned, rinse the monument with
Allow the monument to dry somewhat (it does not have to be
completely dry, but most of the wetness should be gone). Apply a
final application of S/S Biological Solution mixture. The S/S
Biological Solution mixture will continue to kill the biological grow
over the next few days. Under normal conditions, this final
application of S/S Biological Solution will maintain you monument
for up to one year.
In some cases, subsequent applications of S/S Biological Solution
will help prevent future growth of biological growths. This depends
on the location of your monument. Monuments under trees
especially evergreens are especially susceptible to biological
