70% isopropyl alcohol is widely recognized as an effective disinfectant in salon settings for several reasons. It has a balanced concentration that provides optimal efficacy in killing bacteria, viruses, and fungi. This concentration allows for adequate penetration into the microbial cell walls while also ensuring that the alcohol evaporates at a rate that maximizes its disinfecting capabilities.

Additionally, isopropyl alcohol is versatile and can be used on a variety of surfaces and tools, making it suitable for sanitizing equipment like scissors, combs, and other implements used in beauty services. It is often preferred over other disinfectants due to its quick-drying properties and non-corrosive nature, which helps maintain the integrity of expensive salon tools.

In contrast, while a 10% bleach solution can be effective, it is often too harsh for many salon tools and can lead to damage over time. Alcohol wipes are convenient but may not provide the same level of thorough disinfection as a liquid solution. Hydrogen peroxide, although also a disinfectant, is less commonly used in salon settings due to its slower action time and potential for leaving residues. Thus, 70% isopropyl alcohol stands out as the most practical and effective choice for disinfecting tools in a salon environment
