Windsheild cleaning
I don't know how many folks I have talked to, do NOT know about.
Bounty paper towels (MICROWAVE/COOKING). I have used these for 15 years and have not had to replace a windshield yet. These towels are specifically for Microwave use and have No metal recycled crap in them. A lot better than trying to find used socks to do the job. This is just a hint and not an ad for the Company. I DO NOT work for them! Just thought I would pass along for what ever it is worth. Get in touch with the Company and they will verify if you need reassurance. Ok all you no it alls, FLAME Away.

I was told by Kimberly Clark that common paper towels are NOT good for cleaning
polycarbonate or acrylic glass. This would also apply to using tissues on eye glasses. Old style diapers are good for canopy cleaning. GA N39KK |

I bought some expensive paper based polishing towels from a plastics
company. They were touted as the 'perfect' acrylic cleaning rag. Unfortunately, they scratched a test piece of plexy just like any paper towel. The common advice to use only soft cloth rags seems to be well founded. I have polished out scratched canopies and to do it right is a LOT of work. Best to never get them scratched in the first place. There are some good scratch removing polishing compounds available but I always wind up with McGuire's #10 as the final wax. #10 takes a lot of work to do it right but the wax is exactly the same refractive index as Plexiglas so the remaining scratches disappear. There is a story going around that #10 leaves the canopy statically charged which attracts dust. I've never seen this if the polish job is done according to the label instructions.

Wait a while so you don't loose your vision to water explosions. Microwave cleans off like nothing. Or be stupid and spend your money on microwave towels. It's the same thing. How's that for a flame? ;-) Where do I send my bucks? Richard My kind of crowd! I'll be passing a hat around at the next Rutan X-prize launch. ;-) Where'd you learn so much about spacecraft? I'm impressed. By the way Rich, are there any Saturn V or LEM blueprints in existance?; I saw that you hang out at the sci.space groups. I'd kill to get a reproduction to hang up in my hangar. cheers, pac pac Source for orbital trajectories? Principa Mathmatica - Newton. All else follows from that... :^) Heck Pac, nobody believes I dropped out of high school at 17. Nor that I'm considered a 350 credit hour sophmore at 54... For what it's worth, my thesis is to understand exactly WHY the answer to the question of life, the universe, and everything is 42. ( Douglas Adams, who passed away before publishing his research) I found a bunch of detail stuff on Apollo and the LM a while back. My history file only goes back 90 days, must have been longer than that, because it wasn't there when I looked just now. I believe I found that site via a google search for LEM history. But I'll send you some of what I found. Richard |

Flame #1: Use Lemon Pledge for your windshield. It's cheaper than old clumps of Mirror Glaze, works better and the FBO's in the desert that use it have never had to replace a windscreen due to scratches (even with students.) It leaves a slight flim on the surface of your polycarbonate (plexiglass)which suspends abrasive particles. But use the cheapest plain towels at CostCo. I DO work for them on commission, so you must send me a dollar every time you clean you windshield this way. ;-) pacplyer - out I make transparencies for a living, so here go's.... Lemon Pledge.... It appears safe on newer acrylic plastics, but I'm still not convinced. I do know for a fact that the older acrylic formulations (and they do change) can be damaged by use of it. The problem is most likely the propellant gasses used in the Pledge and not the product itself. Now since most product is packaged with isobutane it might be ok. I would hate to recommend a product without knowing what plastic you are shooting it on. Each plastic company specs different UV packages and the monomer mix changes from batch to batch. SO the cautious approach would be to stay away from it if you haven't started. Food for thought. Scott. |
