Will share the first one, just ended up climbing on the roof cleaning solar panels. A lot of spots of sap, accumulated pollen etc. Instant cleaner is higher concentration isopropyl alcohol, I used 99%.
Common product on the market are designed for sap and tar and they don’t work well on sap. On other hand, isopropyl alcohol would not work well on tar.
WD40 also works pretty good for removing tar and sap. Works on the sticky residue from old bumper stickers too. Just wash thoroughly with soap and water when you are done...
