Reddit mentions of Polaroid Super Blower With Hi Perfomance Silicon Squeeze Bulb

These things are pretty effective. They aren't quite as powerful as canned air but they kick up a good amount of dust.

• $30 flash
  
  
• $40 remote flash triggers. There's a $25 version but I haven't used those. These have worked flawlessly for me
  
  
• $15 intervalometer/remote shutter release cable, or the $30 wireless version
  
  
• Maybe a flash stand with a modifier that uses this kind of S-type bracket
  
  
• A nice tripod in the $100-150+ range
  
  
• $6 bulb/rocket blower and a pack of lens cloths from an eyeglass store
  
  
• $125 50 mm f/1.8 lens
  
  
• A kit telephoto lens (55-250 or even a 75-300 is super fun)
  
  
• A trip to practice the genre you're intro lately, or maybe even a new field

A Lenspen will remove the grease. You need one.

I got this one, it's superb and cheaper than the Nikon it seems. 'Lenspen' is a trusted brand, copied by many.

I use the brush first, then the pad, then the brush again to remove any carbon residue from the pad - though this has never been any issue for me.

ALSO....I got a Blower which helps remove larger particles from the lenses and surrounding headset housing.
By using it in reverse, you can actually pick up particles from the headset :)

it looks like it's probably a mealybug infestation :( here's what i would do:

1. quarantine this plant away from any of your other plants. you'll want to put it in a warm, dry place that gets bright, indirect sunlight. ensure your plant isn't getting any direct light as treatment will make its leaves more susceptible to sunburn.
   
   
2. use a q-tip dipped in isopropyl (i.e., rubbing) alcohol to wipe away the white stuff. i have one of these that i use to blow droplets of water off of my succulents after watering them. if you have one, use it to prevent the alcohol from pooling in between your plant's leaves. otherwise, you can use the edge of a paper towel. the alcohol will evaporate away fairly quickly anyway, so it's not a big deal if it pools a little.
   
   
3. check on your plant daily for mealybugs. if you find more, continue treating them with the alcohol.
   
   
4. if the infestation appears to be getting better, continue to treat it as you have. if you believe the infestation is getting worse after a few days, you may need to treat the plant's soil. use a spray bottle to douse the soil with isopropyl alcohol. the alcohol will not harm the plant, its roots, or its soil, so don't worry: it will evaporate away quickly.
   
   
5. once you are sure that the infestation has been dealt with, allow the plant a week to rest and slowly introduce it to direct light. you may want to replant it to dispose of the old soil, but it's not necessary.
   
   good luck with this beauty! with a little love, i'm sure this little one will be just fine :)

Exactly. In most laptops, cleaning the fan means removing the heatsink. Since you removed the heatsink, you'll have to apply new thermal paste anyway.

Half-assed cleaning by blowing compressed air into the exhaust vent is a temporary solution at best (because it only dislodges the dirt but it's still inside the heatsink), and outright dangerous at worst (because there have been cases of fan blades breaking due to the compressed air).

Don't simply rely on the exhaust temperature. Use hardware monitoring software to see the actual CPU temperature.

Read the Hardware Maintenance Manual for your particular model. Google is your friend. In most laptop heatsinks, the fan can be separated from the heatsink, and is usually fastened with small screws.

Removing the fan allows unrestricted access to the heatsink's cooling fins. I use an old toothbrush to remove dirt, as well as an air blower like this one.

Remove all traces of the old paste before applying the new paste. There are dedicated thermal paste cleaning compounds, but 90% isopropyl alcohol works just fine.

This. Try blowing on it, but with a bulb, not your mouth (too easy to get spit on it).

Dust is tough one. But, if you ever feel like you'd like to reduce the amount of it this guy is a cheap and decent tool.

How about a blower?

Dont use a cloth since the cloth will also be dusty. Use an air duster like this. Also you shouldn't keep taking out the lense cups out exposing the LCD.
