If by miracles you mean achieve world peace then no. If you need to disinfect your HVAC because it smells musty then it works. I use this once a year on both cars and it works. It leaves a bit of citrus smell but that soon goes. It is primarily for disinfecting the ducts but also works if you put the HVAC in re-circulation mode.
If you have a real problem with a smelly HVAC then a one shot disinfectant (Normfest make one) or better still an ozone generator works - but you have to use these with care because ozone is dangerous if not used and vented properly.
no i don't have a smelly HVAC.
all HVAC system has bacterias and will eventually smell funky.
i bought this solvent coz it was cheap on ECP, only to test it.
i want to be sure it's perfectly safe to use by asking on MBclub before I start spraying my vents.
do i stick the plastic pipe all the way in and then slowly pull pipe out while i spray richly inside vents?
how often should this be done?
once or twice a year to prevent funky smell?
