What is the best way to clean up the screen on my K75S? It has some scratches and sticker "debris".

I have been using PLEXUS a product from what I hear developed to polish the screens of aircraft. It is expensive but does clean well but the shine doesn't last very long.
I have found too that most car paint polishes will do a fairly good job.
Have a look at some of these I know that Meguires products are good http://www.ebay.com.au/sch/i.html?_sop=10&_from=R40&_sacat=0&_nkw=headlight+polish+kit&_lncat=0&_arm=1&_armm=94&_ruu=http%3A%2F%2Fwww.ebay.com.au%2Fsch%2FMotorcycle-Parts-Accessories-%2F14780%2Fi.html%3F_sop%3D10%26_from%3DR40%26_nkw%3Dheadlight%2Bpolish%2Bkit%26_arr%3D1&_armi=Motorcycle+Parts%2C+Accessories

Boog - it depends on what you mean by "clean" are you looking to remove surface debris or do you need to remove scrathes? If its the latter have a look at post #17 on this thread.

If its the fromer the Rick G's suggestion is one of the best products to use after soap and water or a car wash with a good TFR (Traffic Film Remover). If it's not stating the obvious....mind how you go with harsh chemicals to remove old sticker residue but you should be ok an alchohol wipe, the type used for cleaning spectacles.

Cheers Chap! I will investigate.
I heard somewhere that cheap toothpaste was a good polish...?

toothpaste would/could work as it is a light abrasive but you would need a fair amount to cover the whole screen.... I would imagine that you would have a lovely minty smell from the screen for a while..... That could attract more bugs

Yep - Heard that but never tried it. Brasso is another mild abrasive that others have recommended.

HP Brown Sauce works well, but give the screen a good wash after as it stinks after a while. Think its the vinegar in the sauce that does the work. Great for removing bugs.

Hi Guys
Many uses for WD 40, see list below seems it can be used to clean sticky residue left on windscreens and such.
Removes Lipstick from clothes -



WD-40 – Officially known as Water Displacement #40. The product began from a search for a rust preventative solvent and degreaser to protect missile parts. WD-40 was created in 1953 by three technicians at the San Diego Rocket Chemica Company. Its name comes from the project that was to find a \"water displacement\" compound. They were successful with the fortieth formulation, thus WD-40. The Corvair Company bought it in bulk to protect their atlas missile parts. The workers were so pleased with the product, they began smuggling (also known as \"shrinkage\" or \"stealing\") it out to use at home.

The executives decided there might be a consumer market for it and put it in aerosol cans. The rest, as they say, is history. It is a carefully guarded recipe known only to four people. Only one of them is the \"brew master.\" There are about 2.5 million gallons of the stuff manufactured each year. It gets its distinctive smell from a fragrance that is added to the brew. Ken East (one of the original founders) says there is nothing in WD-40 that would hurt you.

When you read the \"shower door\" part, try it. It's the first thing that has ever cleaned that spotty shower door. If yours is plastic, it works just as well as on glass. It's a miracle! Then try it on your stovetop...Voila! It's now shinier than it's ever been. You'll be amazed. Here are some of the uses:

Protects silver from tarnishing.
Cleans and lubricates guitar strings.
Gives floors that 'just-waxed' sheen without making it slippery.
Keeps flies off cows.
Restores and cleans chalkboards.
Removes lipstick stains.
Loosens stubborn zippers.
Untangles jewelry chains.
Removes stains from stainless steel sinks.
Removes dirt and grime from the barbecue grill.
Keeps ceramic/terra cotta garden pots from oxidizing.
Removes tomato stains from clothing.
Keeps glass shower doors free of water spots.
Camouflages scratches in ceramic and marble floors.
Keeps scissors working smoothly.
Lubricates noisy door hinges on vehicles and doors in homes.
Gives a children's play gym slide a shine for a super fast slide.
Lubricates gear shift and mower deck lever for ease of handling on riding mowers.
Rids kid's rocking chairs and swings of squeaky noises.
Lubricates tracks in sticking home windows and makes them easier to open.
Spraying an umbrella stem makes it easier to open and close.
Restores and cleans padded leather dashboards in vehicles, as well as vinyl bumpers.
Restores and cleans roof racks on vehicles.
Lubricates and stops squeaks in electric fans.
Lubricates wheel sprockets on tricycles, wagons, and bicycles for easy handling.
Lubricates fan belts on washers and dryers and keeps them running smoothly.
Keeps rust from forming on saws and saw blades, and other tools.
Removes splattered grease on stove
Keeps bathroom mirror from fogging.
Keeps pigeons off the balcony (they hate the smell).
Removes all traces of duct tape.
Folks even spray it on their arms, hands, and knees to relieve arthritis pain.
Florida's favorite use is: \"cleans and removes love bugs from grills and bumpers.\"

WD-40 attracts fish. Spray a LITTLE on live bait or lures and you will be catching the big one in no time. Also, it's a lot cheaper than the chemical attractants that are made for just that purpose. Keep in mind though, Using some chemical laced baits or lures for fishing are not allowed in some states.
Use it for fire ant bites. It takes the sting away immediately and stops the itch.
WD-40 is great for removing crayon from walls. Spray on the mark and wipe with a clean rag.
Also, if you've discovered that your teenage daughter has washed and dried a tube of lipstick with a load of laundry, saturate the lipstick spots with WD-40 and re-wash. Presto! Lipstick is gone!
If you sprayed WD-40 on the distributor cap, it would displace the moisture and allow the car to start.
It removes black scuff marks from the kitchen floor!
Use WD-40 for those nasty tar and scuff marks on flooring. It doesn't seem to harm the finish and you won't have to scrub nearly as hard to get them off. Just remember to open some windows if you have a lot of marks.
Bug guts will eat away the finish on your car if not removed quickly! Use
WD-40!
P. S. The basic ingredient is FISH OIL PPS I have no commercial interest in WD40!!

Bought a second hand replacement screen for my K100LT which was a bit scratched - was recommended to use Autosol metal polish by a back street bike mech and it works a treat (tried it on the old screen first because I was doubtful). Came up like a new screen and took all the small scratches away.

Micromesh. It is what we used to use on the perspex Harrier canopy in the RAF and it is great for getting rid of scratches without leaving much distortion.

I think my screen may be a tad worse than most as it's gone opaque, quite similar to how some headlight covers go on cars.

The solution with headlight plastic is to use various grades of wet 'n dry followed by a polishing kit like this one from 3M it sounds quite a drastic approach but does pay dividends if you hold your nerve 

I'll be having a go in the next few weeks and will do a before and after shot.

The screen on my k75rt has started to 'craze' over the last two seasons. It doesn't show in the shade; only when direct sunlight is coming from a specific angle. This isn't scratches. It's something going on within the plexiglass and starts in a spreading circular pattern. I think it might have started because I used a chemical product to try to remove fossilized bug guts, called 'Bugs be Gone', a couple of years ago. I had always used Maguires Plastic Cleaner (does well on aircraft canopies) and it did a great job of polishing and cleaning scratches -  except for those bits of bugs that are as hard as dinosaur sh*t. This 'crazing' has spread dramatically this year. It's not an issue as far as safe riding is concerned. It just looks like hell.
Any thoughts on curing this mess?

Try using Plexus it is a perspex polish that came into being due to the aircraft industry and it gets into the fine cracks and has the same refractive index as the perspex.
I was also put onto one other thing which is Mr Sheen which is a furniture polish but is also good on perspex. A crop duster pilot put me onto it and he used to use it to get rid of the splattered bugs and polish the canopy.  But DON'T use it on a visor as it can effect the hard coating on the plastic and make it go opaque.

Thanks Rick. I'll keep a look-out for those things. I've got all winter now to get at it.

There's one thing you shouldn't put on any type of plastic including acrylic (plexiglass) and that's silicon. Plastics break down when exposed to heat and UVs. The application of silicon products will accelerate this process. It may temporarily cover over scratches and cracks and make your trims etc look new, but it gets into surface cracks and expands when it dries out damaging the plastic and it provides absolutely no protection. This would account for the crazing effect on your acrylic windshield.

Armour All is really bad for this. Some Mr Sheen products are silcon based for use on man-made products like plastics. Use it indoors and its probably ok but expose siliconed plastics to higher temps and UVs and it will cause permanent damage.

For a plastics protectant try 303 Aerospace. It has a high SPF rating.

Maguires also has a good reputation for protecting plastics including acrylic. Its silicon free and has a UV blocker.

Good insight and good advice. Thanks KH.

To remove debris / sticker residue I normally use brake / engine cleaner. It is pure alcohol (normally propanol / isopropanol) and does a good job without doing any harm to paintwork or plastics.
