Can I use benzalkonium Chloride for cleansing after urinating in order to prevent recurrent utis?

"... Prevention

Lifestyle changes may help prevent some UTIs.

After menopause, a woman may use estrogen cream in the vagina area to reduce the chance of further infections.

BATHING AND HYGIENE

Choose sanitary pads instead of tampons, which some doctors believe make infections more likely. Change the pad each time you use the bathroom.
Do not douche or use feminine hygiene sprays or powders. As a general rule, do not use any product containing perfumes in the genital area.
Take showers instead of baths. Avoid bath oils.
Keep your genital area clean. Clean your genital and anal areas before and after sexual activity.
Urinate before and after sexual activity.
Wipe from front to back after using the bathroom.
CLOTHING

Avoid tight-fitting pants.
Wear cotton-cloth underwear and pantyhose, and change both at least once a day.
DIET

Drink plenty of fluids (2 to 4 quarts each day).
Drink cranberry juice or use cranberry tablets, but NOT if you have a personal or family history of kidney stones.
Do NOT drink fluids that irritate the bladder, such as alcohol and caffeine."

It is probably best to cleanse the genital area with warm water only - if you want to use an antibacterial make sure it is well diluted.
