There are several options for controlling bedside commode odors, including liquids and sheets. The right product depends on whether you want to check the color of urine and stool or reduce the need to measure each dose. This article introduces products from seven companies and explains the differences between types and how to use them.
What are bedside commode deodorizers?
It is not always possible to dispose of waste immediately after using a bedside commode. One way to control odors until disposal is to add a deodorizer and water to the bucket. This article introduces deodorizer types, selection points, and manufacturers’ current products.
Types of deodorizer
Types include liquids, foams, sheets, powders, and tablets. Liquids come in colored and colorless versions. Required water volumes and doses vary by product.
How to choose a deodorizer
Colored liquids and foams are options if you want to make waste less visible. If you want to check the color of urine and stool, a colorless liquid or sheet makes this easier.
To reduce measuring, consider single-use sheets, powder sachets, or tablets. Also check your scent preference, ease of preparation, and compatibility with the commode itself.
How to use deodorizers
Dilute liquid products with water according to their instructions. Add sheets, powders, and tablets to the bucket with the specified amount of water. Use foam products as directed to cover the water surface or waste.
Check each product’s label for the required water volume and dose. Even when using a deodorizer, dispose of waste frequently and wash the bucket. For toilets using waste-wrapping systems or disposal bags, follow the toilet’s or bag’s instruction manual.
