Just wondering, I usually seal my windows with a sealant or spray sealant like megs UCW or Opti-Seal. If I need to use window cleaner on my windows sometime afterwards, will it strip the sealant?
Yes, it will degrade and eventually strip the sealant - which is why I use a QD to clean my glass (I like Poorboy's Spray and Wipe, it seems to streak the least on glass among the ones I've tried, which include UWW+, ONR, OID, and DP RWG).
