How to clean plastic bottles using dishwashing soap

This is probably the easiest and fastest working method to clean the insides of your plastic bottles.

  1. Add some warm water halfway up your plastic bottle, and add a few drops of any dishwashing liquid into the bottle.
  2. Now, shake the plastic bottle in up and downwards motions, sideways and circular motions to really get the soapy water all over the insides of the plastic bottle.
  3. Using a special bottle brush, scrub the inside of the bottle cap as well as the insides of the plastic bottle gently. I use the OXO Good Grips Bottle Brush, which you can get on Amazon.
  4. Scrub the insides of the plastic bottle properly to reach all the nooks and corners of the bottle.
  5. Leave the bottle in the open air to dry naturally.

How to clean plastic bottles using vinegar and baking soda

Vinegar and baking soda can help to clean and sanitize the insides of your plastic bottle effectively for you to reuse your bottle without the fear of germs.

  1. Vinegar is an ideal cleaning product as well as a good sanitizer. Fill up your plastic bottle 1/5th of the way with white vinegar, and fill the rest of the length of the bottle with warm water. Add just a teaspoon of baking soda to this solution.
  2. Allow this solution to sit overnight undisturbed, and in the morning, rinse out the inside of the bottle with hot water and towel dry the bottle.

How to clean plastic bottles from inside using rice

Raw, uncooked rice can be extremely helpful in cleaning the insides of plastic bottles, especially those bottles which are irregularly shaped.

  1. Add a few drops of dishwashing soap, some warm water, and fill the inside of the bottle up to 1/4th with raw, uncooked rice.
  2. Make sure that you fill the rest of the part of the bottle with warm water without leaving much space inside.
  3. Vigorously shake the bottle in every direction for about a minute or two. The rice will reach into all the nooks and corners of the bottle which a brush might not otherwise reach. The warm or hot soapy water will help loosen up any sticky residue inside the bottle.
  4. Empty out the contents of the bottle using a strainer so that you can catch the rice and not let it fall down your drain, as this might clog your drains.
  5. Rinse the bottle thoroughly using clean water, and repeat this process a few times if you feel necessary.
  6. Use an antibacterial soap to finally rinse out the inside of the bottle and remove any final residue, before reusing the bottle again.

How to clean plastic bottles using salt

  1. Add a few teaspoons of coarse salt to the inside of your bottle, and fill up the bottle with hot or warm water.
  2. Swirl the bottle around so that the salt reaches all the little ends of the inside of the plastic bottle.
  3. Empty out the contents of the bottle and rinse it out well with an antibacterial soap, or using a drop of bleach. Make sure that you rinse out the bleach well before using the plastic bottle again.
