O heat does not only bring days smelling of seaweed – the temperatures will rise again and, in some cases, this may be synonymous with bad odors – even on the beach.
However, the spread of undesirable smells never comes alone.
Cleaning experts reveal to The Spruce the everyday objects that, when they are not properly cleaned, they can raise more health concerns.
Discover below the objects that can become a “paradise of bacteria”.
Water bottles
This notice applies in particular to reusable bottles, since they end up making longer use, especially on the hottest days.
However, in the rush of day to day it is too easy to forget to clean them properly. Although the bottle may be in contact with numerous surfaces, the most problematic part, according to these experts, is not the bottle itself.
Murphy explains that moisture can be retained in large quantities near the surface of the lid and everything it involves, including rubber coatings.
“ Rinse quickly, it is usually not enough,” says Robin Murphy, chief cleaning officer at Maid Brigade House Cleaning and founder of ChirpChirp.
How do we ensure that the bottle is well sanitized?
“ Be sure to unmount the lid when you can and wash the removable parts with a small brush that reaches the areas you cannot see so easily”, the expert proposes.
Garbage boxes
This doesn't just apply to street trash cans! Although the effects are more noticeable in circumstances where the sun affects these surfaces, the household waste buckets are also greatly affected. Therefore, to minimize the damage, the ideal is not to expose the garbage cans to direct heat sources – whether the sun or the heat released by the oven.
“ Higher temperatures can increase odors, even if you put exactly the same packaging and food waste that you put in the trash during the winter,” describes Kellsie Zapata, founder of Zapata’s Cleaning Services in Georgia.
In addition to bacteria, to avoid the unwanted appearance of animals, the specialist recommends cleaning the garbage cans thoroughly at least once a month during the summer. “Always moving forward with maintenance is much easier than having to restore it later,” he adds.
