Well I live near a few tall pine needle trees. During some windsotrms My cover will get covered in small pine needles. Most of this will be washed out driving but some get stuck in the covertible bottom area like under theplastic window and to the sides where you can't reach hand into to pull em out. These are very small pine needles. When I wash my car I'll put the hose in the area right under the plastic window area where it goes in the car which flood alot of the needles out. There is still some which don't seem to be coming out. Is this a major problem? I havent oerated my top since october and won't be until warmer weather hits around in march or so. Am I worrying to much or is it natural for some debris to fall in through the sides and back. Just small pine needles and not alot of them since they eventually get flushed out.

 

not a major problem... but worth cleaning out imo- those things do have sap potential.
to clean the area that you refer to, just slightly lower the top (unlatch it and raise it a few inches only). this should loosen the area that you are describing and should allow you to get all the stuff out.
let us know how this goes!
