Topic Explanation:
The discussion revolves around finding DIY alternatives and safety tips for ileostomy deodorant due to Medicare reducing the allotment of ostomy deodorant to one 8 oz bottle per month. The original poster, who has been using Hollister M9 deodorant, finds this amount insufficient and is seeking advice on homemade substitutes, specifically asking about the use of mouthwash and dilute hydrogen peroxide, while being cautious about the concentration to avoid irritation of the stoma.

Extracted Advice and Helpful Insights:
1. Alternative Deodorant Solutions:
- Baking soda is suggested as an inexpensive and effective odor absorber. It can be scooped into the bag after emptying.
- A mixture of pre-dissolved antacids in water can be used to flush the bag and neutralize odors by raising the pH level, which inhibits digestive enzymes responsible for odor.
- Antibacterial dish soap mixed with water can be used to wash and flush the bag, helping to clean and deodorize.
- Peppermint essential oil and aspirin have been mentioned as potential deodorants, though aspirin's safety was questioned due to its acidic nature.
- Hydrogen peroxide can be used as a rinse or flush in small amounts (3-5 cc) to manage odor effectively and inexpensively.
- Commercial alternatives like Safe n Simple deodorant/lubricant were noted for being cost-effective and efficient.

2. Safety and Effectiveness Concerns:
- It's important to consider the pH levels of substances used in DIY deodorants. Antacids are safer as they only slightly raise the pH, unlike aspirin which is much more acidic and could potentially harm the stoma.
- Full-strength hydrogen peroxide has been used successfully by some without causing irritation, but individual experiences may vary.
- The effectiveness of homemade solutions should be weighed against commercial products like M9, which some users find unparalleled in performance.

3. Cost Considerations and Insurance:
- Users should calculate the cost of DIY solutions against purchasing additional commercial deodorant, considering both materials and time.
- Checking with insurance providers and suppliers about coverage limits and possible errors in supply limits can sometimes reveal misunderstandings or miscommunications that can be corrected to access more supplies.
