Furthermore, unlike ozone treatment, you can immediately get back into your vehicle after disinfection. In contrast, after ozone treatment, a waiting period of 24 to 36 hours is typical. The ozone odor can even linger for up to six months afterward. Air Clean leaves no odors or unsightly residues on the dashboard, upholstery, or other vehicle surfaces, except for a brief, "swimming pool" smell. Swab tests conducted by an independent laboratory have proven that the new disinfection method is effective against bacteria (even MRSA , MSSA, etc.) and viruses in just ten minutes, eliminating everything. Remove musty odors from your caravan.
