Having a tough time with this one.

Plexus (Sp?). Originally designed for cleaning and protecting airplane canopies. It's an aerosol spray can (black and blue w/ white top). Even makes small scratches diminish. I ordered online from Quadratec (use it on my Jeep soft top too), but have seen at some auto parts stores as well.

Do not use paper towels. Always a soft cloth with whatever spray you have.

Yeah I knew that one also, I checked the manufacturers site and they say mild soat and water but do not wipe dry. OK, how the hell do you keep it from spotting if you dont wipe it dry? And Kachina made their canopies to where half of the underside isn't even accessable so i will probably wind up putting threaded sleeves so I can run allen caps on em to remove and clean about once a month during season. I tell you what, a 34 is twice the work of a 30 to keep clean, no joke.

Try going from a 27' to a 38'. Seems to take forever to clean the bow, and I don't even want to talk about waxing.

I wash the windshield with mild soap, LOTS of water and a clean soft sponge. Then rinse and dry about 95% w/ an Absorber. Then spary with Plexus and polish with a clean cloth. Works great.

You can try a squeege, but you need one that's very flexible to follow the contour of the canopy. One like this:

That one is made for paint, so I'd bet its fine for your canopy.

Three Days Only ( another member on here) told me before I even took delivery that when I came out of the salt to douche the hell out of the canopies and no rubbing because of the salt accumulation. That part is fine and the sponge idea sounds great. I'll give it a whirl.

Cut and paste this link Ken, this is what I use on my windshield.

If not my detailer has it, I'll ask him where he buys the stuff from. I sub him out for work every now and then.
