A milk of magnesia solution, mixed with 10% magnesium chloride powder, or magnesium oil should keep the pH within a good range that it doesn't get irritating. It may be used internally in the uterus area. Another one I used was 1/8 teaspoon per 2 liter bottle of water of potassium permanganate used as a wash for uterus. The normal mixture for potassium permanganate concentration is 1: 10000 concentration. 1/16 teaspoon potassium permanganate per 3 liter of water is the dose I used. Roughly speaking, 100 mg per liter is the standard concentration. In a teaspoon is equal to roughly 5000 mg. So 1/2 is 2500, 1/4 is 1240, 1/8 is 620, 1/16 is 310 mg. So the concentration is more suited for 3 liters here, but I prefer to make it slighly stronger then the 1:10000, but in general it's close enough. Most people I assume don't have a cheap digital weighing, so a standard teaspoon measure should be enough. The mixture after mixing can be used as an internal wash in uterus area. It is in general non irritating when the potassium permanganate is properly diluted here and may be used as frequently as required. As for the milk of magnesia this can be used too as a wash, but is in general drying, and hence some magnesium oil or magnesium chloride is added until the pH paper is a bit on the neutral side so it won't be too iriitating. There are other antiseptic solutions that is currently used in some studies the kill within less then a minute with MRSA when we used povidone-iodine (betadine) applied to the area infected, undiluted, of course. That's the remedy or part of the remedy that I used for genital herpes as well. The betadine may be diluted by 1/2 if it is too strong but I won't dilute it further as it is too weak. If it becomes non-irritating externally, I can used the same concentration internally too. Acai sometimes help but don't do it because sometimes they add other things to it which reduces it's effectiveness, is another possibility. Silver sulfadizine is another one they used, at 1%, but it's not easily available and I haven't tested that one yet, but i would likely used it for external application. Other things I found helpful against MRSA were benzalkonium chloride, copper sulfate solutions, caprylic acid and tea tree oil. The most interesting was the benzalkonium chloride roughly between 0.1% to 0.5% in any lotions, honey, or creams that can be applied. If of course, you can get benzalkonium chloride, you just mixed it yourself, or get some from drug stores that has the benzalkonium chloride at the concentration mentioned I found to be helpful too. The potassium permanganate solution at 1:10000 concentration can be used inside a canal, one of my friend used it to clean her uterus whenever there's an infection, itch and is used as a general antiseptic solution.
If the potassium permanganate solution at 1/16 teaspoon per 3 liters of water is too weak, i sometimes used 1/16 per 2 liter of water. Under both mixtures I don't find skin irritation for general use.
A preferred benzalkonium concentration I like is about 0.15% concentration, in case you want to be more exacting.
Again the concentration maybe increase/decrease depending on effectiveness versus the irritation to the skin it caused. Less irritating we may increase greater concentration for greater effectiveness.
Tea tree oil maybe irritating to some, not irritating to another, but if it is irritating we may dilute the mixture with appropriate oils such as coconut oil or olive oil.
I haven't quite experimented with a mixture of xylitol, or other polyol sugars mixed with the milk of magnesia, but I do know they prevent the bacteria from attaching itself to healthy skin, thus reducing the infection.
