Dirt 2 Highly Compressed

[Bran Cardello]

Sprayingcompressed gas or using a vacuum, the results will vary based on the laptop's design, as well as what kind and amount of debris is stuck inside. That being said, compressed air does come out with more force than a vacuum. If you really want to clean out a laptop, you will likely need to remove the cover to expose the motherboard and the fan. Then you can use compressed air to thoroughly clean the dust.

I'm not advocating it - as its definitely not a best practice due to moisture - but I've also had success using an air compressor (once even at a petrol station) to very quickly.clean a dirty system) and indeed I do this regularly to unblocked heavily clogged [water] filters which vacuuming would do little for. I have not tried them (yet), but you can get devices to put on an air compressor to remove the moisture.

Take a look at this page, it gives instructions to change the viewfinder screen,...basically you'll do the same, just after cleaning replace the same one. Look also at the botton of the page and you will find the solutions that are acceptables as cleaners. Never touch it with your fingers.

I will highly recomend the use of special plastic tweezers and the plastic box where the screen comes, because the tweezer will handle the screen from the camera to the box( where there is a slot to place it in vertical position for cleaning ),and back to the camera. Just steady hands and be delicate and is a breeze.

Bal, another thing. If you don't have the tweezer and the box,I have one lying around from a viewfinder I ordered to replace one I TRIED TO REMOVE, CLEAN AND REPLACE W/O THESE TOOLS (of couse you guess the out come, I scratched and ruined the screen, therefore I oredered a new one. That was a while back, now I have some others ones , so I will be not in short supply of these tools.

1. Remove them (I use fingernails, but if you have never done it before I recommend the tweezers that come with each accessory screen) -- pull out the release latch and the screen+frame falls loose. Remove carefully by holding on to the tab located at one side.

Arnab Pratim Das insturctions are very good. Depending on the condition of the pipes in your building they can have oily, rusty gook in them and it can make a mess. Ive used unfiltered running water in my current house once but the last house I use HD filtering for film washing and that was the only tap water Id let touch a screen there. To be on the safe side you can use several rinses in bottled water.

99.9% Ethyl Alcohol is the preferred viewing screen cleaner and final wash by a repair guy I know. Methyl will eat some Canon screens. I think my friend uses USP grade Ethyl. You might get way with using 98 Proof Vodka as its 49% ethyl, 51% distilled water. Drying marks can be a problem even with alcohol. I think he blasts the screen off with highly filtered compressed air. I use canned air.

The F3 screens and other true F series cameras have an optical glass condenser on top and the focus screen proper on the bottom. The focus screen on the bottom is made of the same material as the FM3a, FM2n, etc. The two are sandwiched and tapped together with a thin strip of clear tape then mounted in an aluminum or polyfiber frame.

I insert a large diameter drinking straw [Starbucks has them in their Computer Cleaning Section of every store);-)] into the slim angled attachment which comes with most vacuums, I then tape the straw to the outside of the attachment creating a seal. It is a simple matter then to take an ESP Brush as mentioned above and use it to brush the dust into the straw which sucks it into the vacuum cleaner. Where it goes from there I have no idea!

I have encountered a similar problem while cleaning dust and grime off PCBs for re-soldering/repair. Usually, the dust has accumulated over time, and due to moisture which can't be removed with compressed air.

This is useful for cleaning motherboards, GPUs, fans and heatsinks. If cleaning a CPU/GPU die, take care and use some Iso., both on the die and the heatsink contact. Always reapply thermal paste after.

I was about to make a special tiny nozzle for my hair dryer (on cool of course), before I discovered a powered duster and bought that instead. You asked about a household item, so I'd go with the nozzle. I also briefly considered a balloon and a straw...

Instead of expensive cans of air, I use the blow gun on my cheap ($50-on-sale) 1-gallon compressor. There is a slight chance of water droplets forming, but it won't be as bad as human breath or the stuff that often falls into keyboards.

Depending on how the crevice to clean is shaped, an old (but reasonably clean) toothbrush can work quite well.This seems to work well on the narrow spaces where plastic pieces come together, or decorative grooves in a device, where dirt or dust sometimes builds up.

How about just using a drinking straw and blowing out the dust? I had pretty good luck blowing dust out of a CPU heatsink that way. Or, maybe blow up a balloon and wrap the end on a straw for more force.

Although I haven't tried it, I would imagine a bicycle pump would work. If you taped the "straw" from your old can to the end you could probably make it more directional and higher pressure. The adapter for pumping up footballs might also help in this regard.

To add to existing answers: one desperate but great way of cleaning really messy keyboards is the dish washing machine. Place the keyboard key-face down and run the program, including detergent and all as you would your dishes. You can also wash some of the usual things with it as long as they are not too dirty (mugs, cups, plates as long as there is no food on them).

After the wash make sure you allow the keyboard to dry completely. Shake as much of the water out as you can, then place it close to an open window or onto a radiator. Don't use it, until you are confident all the water has evaporated. Water will not normally damage electronic equipment if there is no power.

But keep this as a last resort - in some cases the keyboard will after all not survive this operation. My own experience with this has seen no losses so far though. Anyway, this hack is very appropriate if you were considering to bin the keyboard rather than cleaning it.

In midtown Manhattan, the street crossings surrounding the entrance to the Lincoln Tunnel were once some of the most challenging in the city. A mess of highway ramps, missing sidewalks, and concrete barriers made the corner of Dyer Avenue and 30th Street an area to avoid.

On their way, they can take a moment to experience a woodland landscape and a marvel of glulam wood engineering designed by landscape architects at James Corner Field Operations (JCFO) and architects and engineers at Skidmore, Owings & Merrill (SOM).

The new pedestrian passage can be expected to be used by tens or even hundreds of thousands of people a year. Pre-Covid, the High Line saw eight million visitors annually; and the train station has already welcomed 700,000 travelers.

And JCFO, which has designed the High Line since 2004, notes that the connector is just one of new access improvements for the elevated park. A street-level plaza at the edge of the park on 18th Street is in development, and additional spaces to integrate the High Line into the community could happen in the future.

The woodland bridge is an extension of the landscape of the High Line Spur, which veers east off the main route of the High Line for half a block at 30th Street. Connected soil beds built into the black steel structure support 60 trees, 90 shrubs, and 5,200 grasses and perennials.

Made of glulaminated Alaskan yellow cedar wood from British Columbia, Canada, the connector also advances more sustainable practices. The highly compressed wood layers sequester carbon, and construction of the beams released far less greenhouse emissions than a steel alternative.

I was changing a bad spark plug on my F150 4.6L V8 and despite cleaning the spark plug well as thoroughly as I could muster (rearmost cylinder and under the dash pretty well so very little clearance) I can't guarantee a bit of the residual dirt from the well didn't make it into the cylinder. For a bit more context, getting the new plug lined up took a couple attempts and each time the anti-seize had to be cleaned off and re-applied due to sediment sticking to it, not a whole lot but more than I really wanted to risk with the soft aluminium heads on these engines.

What are the risks of starting the engine at this point if some sediment did make its way into the cylinder. Will it just get blown out pretty well right off or will I be risking damage to the sleeve or valves (or anything else further down the line). Would I be further ahead to remove the spark plug and try to sneak a line down into the cylinder and try to blow anything out (keeping in mind that may introduce new contaminants)?

A small amount of dirt would usually not cause an issue. It also depends on the size of the dirt. Most "stuff" which would be sitting where you're talking about is probably fairly small. The biggest worry is if it gets stuck at the side of the piston and is forced up and down the side of the cylinder wall. This will cause a wear track in the cylinder and will just continue to damage it until it is dislodged.

More than likely what will happen is, on first start up the debris will be blown right out of the exhaust port. Mind you, it can get caught up in the catalytic converter downstream, but it really shouldn't cause much of an issue there, either. This is mainly due again to the size of the debris. While the honeycomb of the cat is fairly tight, there is some room for passage of very fine debris. More than likely it will just clog a single passage (or maybe two, depending on the size of the debris), but really shouldn't affect efficiency of it much at all.

Your better bet the next time you go to change out spark plugs is to use compressed air and a shop vac before you remove the plug. Use the compressed air to dislodge any foreign matter, and the shop vac with a tight nosed attachment to suck it up as it flies out. This way you won't have to deal with it another time.
