Clean and dry means that there are no foreign matters which have an effect on the composition of the standard solution. Foreign matters like minerals, bacteria or just calcium or dirt directly influence the composition.
A wash bottle containing a solution of alkali can be used to neutralize acids on surfaces or equipment. It can also be used to rinse or clean glassware in a laboratory setting.
To properly clean and maintain a wash bottle for laboratory use, first empty any remaining contents and rinse the bottle with distilled water. Then, fill the bottle with a cleaning solution, such as a mixture of water and detergent, and shake it well. Rinse the bottle thoroughly with distilled water and allow it to air dry before refilling it with the desired solution. Regularly check the bottle for any signs of wear or damage, and replace it if necessary.
To safely clean your water bottle with bleach to remove traces of TSP, first rinse the bottle thoroughly with water. Then, mix a solution of 1 tablespoon of bleach per gallon of water. Fill the bottle with the bleach solution and let it sit for 5 minutes. Rinse the bottle thoroughly with water and let it air dry. Make sure to follow safety precautions when handling bleach, such as wearing gloves and working in a well-ventilated area.
To remove a spilled bottle of shampoo from carpet, first blot up excess liquid with a clean cloth. Then mix a solution of dish soap and warm water, apply to the affected area, and blot until the shampoo is lifted. Finally, rinse with clean water and blot dry.
To clean scum off glass, mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the glass surface and let it sit for a few minutes. Wipe the glass clean with a microfiber cloth or sponge.

To effectively clean and sanitize your water bottle for safe reuse, wash it with hot, soapy water and use a bottle brush to scrub the inside. Rinse thoroughly with clean water. To sanitize, you can use a mixture of water and vinegar or a diluted bleach solution. Let the sanitizing solution sit in the bottle for a few minutes before rinsing thoroughly. Allow the bottle to air dry completely before using it again.
Diluted vinegar solution can also be used to clean brass. It can be prepared bymixing one part of vinegar with ten parts of water.

To effectively clean bottle nipples and restore their clarity, soak them in a solution of equal parts water and white vinegar for about an hour. Then, scrub them with a bottle brush and rinse thoroughly with hot water. Repeat if necessary until the nipples are clear.
Standardized Sodium Hydroxide (NaOH), as most laboratory chemicals should be stored in a sealed bottle to avoid evaporation of the Water portion, which in turn would increase the concentration of the NaOH over time. (this can be observed experimentally by placing a drop of the NaOH(aq) solution on a safe surface and allowing it to evaporate. The H2O(l) will evaporate leaving NaOH(s) behind in the form of white crystals.) Additional advice which is important with NaOH in-particular is to store the solution in a bottle that does not use a (ground) glass stopper. This is because NaOH dissolves glass. When in low concentrations this process precedes rather slowly, and may simply make the glass-on-glass stopper joint difficult to open. Stronger solutions are capable of freezing the joint permanently! (for an extreme example Sodium Hydroxide heated above its melting point to the liquid phase readily dissolves solid glass into a solution! This is not an experiment that should be attempted but only used for comprehension of why the phenomena occurs)
Vinegar is a dilute solution of acetic acid and is created by diluting concentrated acetic acid 20 fold to create a 5% acid solution.
Assuming the numbers are meant to be fractions ... 3/5 of bathroom uses 1/3 of bottle, so 1/5 of bathroom uses 1/3 x 1/3 = 1/9 of bottle. Then 5/5 or entire bathroom uses 1/9 x 5 = 5/9

To clean and sterilize an infant feeder bottle effectively, follow these best practices: Wash the bottle with hot, soapy water after each use. Use a bottle brush to clean hard-to-reach areas. Sterilize the bottle by boiling it in water for 5 minutes or using a sterilizing solution. Allow the bottle to air dry completely before use. Store the bottle in a clean, dry place. Following these steps will help ensure the health and safety of your baby.
The best way to clean glass is with a vinegar and water solution. A 25% vinegar solution should be more than plenty. Spray it on, if you have a spray bottle. Most dollar stores carry them. Use newspaper to clean.
Sodium thiosulfate solution is prepared in freshly boiled and cooled water to remove any dissolved gases or impurities that could interfere with its chemical reactions. Using boiled water helps ensure a clean solution for accurate results when used in reactions, such as in titrations or photochemical processes.
