Rubber can sometimes have a strong smell.
In the manufacture of technical rubber products, additives or chemicals such as fillers, plasticisers, cross-linking agents, accelerators, anti-ageing agents, release agents, etc. are required in addition to the base rubber. The addition of these chemicals causes the typical rubber smell, which may be perceived as unpleasant.
Fortunately, the rubber smell dissipates on its own over time.
Here are a few tips on how to speed up the process of removing odours from rubber: Air the rubber product out in the fresh air for a while. Rub the rubber product with diluted vinegar and leave it to soak for a while. After about 1 hour, rinse the rubber product with water. You can repeat the process if necessary.
