The fins are aluminum and may be affected by chemicals. I also fabricated a fin protector from some fiberglass screen material, stapled to two boards, glued on some magnets.

If your are concerned and have a removable panel on the plenum (bonnet) you can also spray the coil down and pour clean water to rinse making sure the water drains from the condensate drain tube.
