Citrus II CPAP Mask Spray Cleaner, suitable for cleaning and deodorizing all types of CPAP, BIPAP, APAP or Oxygen Therapy Masks, Tubing and Accessories (can even be used on other medical equipment, such as wheelchairs, canes and walkers etc). Cleaning is a top priority for your masks and nasal cushions, and these safely and gently cleanse and deodorize them with no damage to your equipment, as they contain NO ALCOHOL and are SOLVENT FREE! They are made solely from natural ingredients (corn, citrus and coconut). They are designed for daily use to gently remove dirt, oils and organics from masks and tubing without leaving any after-odour Each container holds 8 fl oz of ready-to-use Spray Cleanser, and you simply spray onto your mask etc, rinse with water and dry. The sprays are easier to clean your tubing and hard to reach humidification chambers, than the convenient wipes (on a separate listing). It is personal preference on whether you prefer the wipes or the spray. I use both! IMPORTANT DO NOT use any alcohol based products on your masks. Other users of this product (including myself) have commented their masks seal better after using them, and also prolongs the life of the masks. I have personally tried a few different products, and these are my favourites. I have been using them for the past 2 years, and cannot rate them highly enough!
