To have a pleasant odor in a room, you need to drip a couple of perfume drops on an unlit light bulb. If there is a musty smell in your fridge, you have to put black bread slices on the shelves and hold them in a closed refrigerator for several hours. To get rid of a specific smell in the place where the bread is kept, you need to wipe this place with a cloth dampened with vinegar from time to time and air it regularly. Unpleasant odors in a cupboard can be removed...

The stains of organic origin are removed with stain removers, which include reducing agents (sodium hydrosulfite or its derivatives), oxidants (hydrogen peroxide), as well as various solvents and other substances. Their action is based on the fact that they convert coloring matter to the colorless one which is easily washed out. To remove stains from juice, berries, fruit, ink, wine from any fabric use powdered cleaners and pastes, indicating that the stain remover is used for...

Why not create a trash bin which will consist of several disposable and recycled paper containers nested inside one another? This will eliminate the need for plastic can liners. Such a bin would be the ideal choice for disposing of paper products, since the contents and bag could all be recycled together. It would also be suitable for dry biodegradable materials, and could be used in compost bins.

A new ultrasonic nozzle will use ultrasound technology to increase the cleaning efficiency of ordinary water while also reducing water use. The nozzle will differ from conventional ultrasound cleaning devices by the addition of bubbles, which will scrub the nooks and crannies of the material. The power will be set to low or high, and device will use one tenth the amount of water as a conventional pressure washer. It will also reduce the chances of contamination by putting less...

The idea is to place timers on the doors of individual toilet cubicles. This will let people know how long it is since someone else last used the cubicle and see which one has been vacated and "aired" for the longest time.

The idea is to create a portable laundry machine that will be operated by hand crank much like a salad spinner and use zero energy. Ideal for small spaces, mobile lifestyles, and displaced living, the laundry machine will be simple to use. Clothes, water and detergent will be added to the machine to soak. The user will then agitate and rinse the clothes by spinning the crank and draining or adding water as needed. Clothes will be spun partially dry in the same manner. The...

A newly developed liquid in conjunction with bacteria-killing gas will use viruses to help break down the resistance of antibiotic resistant bacteria, rendering them vulnerable to conventional cleaning products. The liquid will take advantage of virus infecting bacteria called bacteriophages. The bacteriophages have been engineered to restore a gene in the bacteria that they have lost in the process of becoming resistant. The liquid should cost only a few dollars per liter.

A self cleaning cloth will be able to destroy bacteria and toxins when exposed to light, which could be used to make safer clothing for farmers and medical workers. The cloth could be developed by incorporating the unusual compound 2-anthraquinone carboxylic acid (2-AQC) into the fabric. The compound will bond to the cotton without changing its properties, and produce hydroxyl radicals and hydrogen peroxide when exposed to light, which instantly will kill bacteria and break down...

Why not invent a "smart" Christmas tree - one capable of retaining its needles for twice the normal length of time?
