How to avoid fungus on Digital Camera Lens?


The dreaded fungus is something that bothers every photographer. I have suffered from it before, and every coming rain gives me constant worries of possibilities of fungus growing somewhere inside my lenses. I am more vulnerable to fungus than most people because I don't think much about taking out the camera to get some good shots even if it has been raining a bit, and have often got plenty of rain drops on the camera and the lens therefore.

Where does fungus comefrom?
  • Fungus spores are everywhere and germinate under suitable environmental conditions:
  • Relative humidity of at least 70% (more than 3 days)
  • No or little airflow
  • Darkness
  • Nutrients (textile lint, traces of grease, varnish, dust and dirt)
  • Temperatures between 10 and 35°C
How can fungus be avoided?
  1. Silica Gel. This seems to be the easiest and common way to avoid fungus, but I haven't had much success with it either.
  2. . Store the lenses in an airtight container. Again, you may need to put a few Silica Gels in the container. Putting too many of Silica Gel is known to dry out the lubricants in the lens, so you need to use your discretion with quantity of the Silica Gel.
  3. . A popular idea is to install a low wattage tungsten bulb in the closet where you keep the lens. This will keep the place warm and dry, preventing the fungus. This is known to work.
  4. . Store the lens in transparent container. Fungus is known to fear light and love darkness. Also make sure that the lenses are not stored in leather bags, as leather can easily attract fungus.
  5. And finally, of course, the best way to prevent fungus is to get out and shoot more often.
  6. After the work is done, immediately clean the instruments. If possible, you can use a fan or blower to facilitate evaporation of surface moisture.

My 1.9 diesel bravo has been in the garage for two weeks not starting in morning got they said fuel is congealing changed all filters still same problem


for diesel fuel to congeal it has to be poor quality with a high paraffin content close to 0 degrees c or contaminated. I would go for contaminated from a fungus growing in the fuel. Get a sample of the fuel from the tank and if it is a grey slimy mess then that will be the fungus. All diesels use a return line from the injectors that lubricates and cools the injectors.and this hot fuel creates a humid atmosphere in the tank so hat when the tank cools down the fungus grows in the condensed water. Try a wynns diesel fuel treatment product as it is pretty good at killing the fungus and cleaning the tank out.

What is the cure for yellow leaf on tomato plants


Usually fungus. You need to plant tomatoes where the sun will dry the overnight dew quickly each day. Don't water at night (water in the morning). Try to water the soil and not the leaves.

Ask your nursery for a fungicide (or if something else is causing yellow leaf in your area). They will know and guide you.

Best set to pull off the dead/yellow leaves to limit cross contamination and spread of the fungus/mold.

I have a Sanyo SVGA DLP PDG-DSU30 projector. There are small white spots with some black on the screen projection. I'm not sure if its fungus in the lens. Can I remove the lens for cleaning or is it a...


Not many funguses can thrive under the intense heat from the lamp. The Ultraviolet light that the lamp produces reacts with the plastic lamp housing and deposits a film on the optics and color wheel. They can be cleaned with water. I would not use any chemicals on the optics or color wheel since they leave a residue behind.

I have the akai model # ptf492s and the white colors are yellow


I'm almost positive the problem is you have fungus in the CRTs. I know this sounds strange, but it's true. Basically there is coolant fluid in the lamps that develops fungus over time and turns yellow. It should be clear. If you take the back off the television, you will see the 3 lenses (red, green, blue) Each of the lens is held on with 3 screws. Remove the adjustable lens and look at each CRT. Shine a flashlight in they should look white. From what I've read, blue develops the problem first, then green. You can replace the fluid. Look up TV coolant replacement online. It's not to difficult, but you cannot get any of the fluid on the circuit boards or it will ruin it. Mine had a lot of fungus in the blue CRT and a little in the green. The picture looks 100% better now. Good Luck.

Defective part


To better address the problem with your nonstick pot... I need more information on the steps you have used to clean the pot and the extent of damage to the pot itself.

You indicated that the damage has occured between the pot and the inner surface of the cooker base? Is this a corrosive damage or a build up of material on the inner liner of the base?

Often times a build up of 'hard water' minerals accumulates on the inner surface due to condensation and occasional overflows from the foods being cooked. They can appear to be a type of fungus or mold.
