Starting out I have used a bonnet cleaner while pre-spraying the encap down. I found this method to be a little more time consuming than running the encap through the bonnet driver itself, but it saves on Chem and drys a bit quicker. I also am not a fan of Encap ONLY cleaning. I use it as a maintenance clean in between HWE for commercial and don't even offer it as a residential product.... Thoughts?
