I was surprised today by an email from WSDOT, they said its Calcium Chloride with a corrosion inhibitor blend. I think they ordered the wrong stuff and got corrosion enhancer. I was pretty happy about the snow and even got a snow day from work, but in the future I will hope for rain.
Here is the email:
Thank you for your e-mail to the Washington State Department of
Transportation (WSDOT) asking about the deicer used on the state
highways.
The liquid deicer used in your area is CC&B. It is a Calcium Chloride
deicer with a corrosion inhibitor blend.
There are a few products on the market that are specifically designed to
breakdown deicers. However, they are usually quite expensive. I am
including for your review, a link to a product that we currently use in
our fleet division.

While we do not endorse this product over any of the other products that
are currently available, we have had success using it on our equipment.
WSDOT also recommends that drivers who drive on roads treated with
deicers, manually wash their vehicles or drive thru a mechanical carwash
to help prevent build-up over time. Normal car wash soap with agitation
will remove most deicers.
For information about our snow and ice removal program, including
deicers, please see our website at

If you have further questions about deicers, please contact Jay Wells,
WSDOT HQ Maintenance and Operations Staff Superintendent, at
360-705-7863 or
