Any other verruca treatment?

[Jokat]

Please help. My now 13 year old daughter has had verrucas on her feet since she was about 4. Amongst single ones, she's also had a cluster (I think it's called a mosaic verruca) that has got bigger and more pronounced over time. They are not hurting her, but especially this big cluster is having us worried as it is such a lump on her foot. So far, we've tried:
Bazooka; bazooka extra strength; some freezing home kit; silver nitrate; duct tape; banana skins; having a healer speak to it (we were desperate at this point); professional treatment from a local podiatrist who comes very highly recommended; she has treated it so many times now that she said the next step will be freezing or needling it, which my dd categorically refuses at this point. We have now started using hospital grade antibacterial/antiviral gel twice a day.
Can anybody recommend anything else? I'd be hugely grateful.

My dad used to cut mine out with a Stanley knife blade.

My grandad used to snap dandelion stalks and rub the sap / milk into them for me

I used to have loads, they also do go away on their own sometimes but took YEARS

I’ve got an annoying one on my head now that I’ve had for years but no sign of vanishing yet

My son had a very large stubborn one on the side of one of his toes (so quite hard to reach). We used (after many failed attempts) bazuka extra strength which was applied religiously every night, left to dry and then tightly wrapped in a plaster. Adding the plaster over the veruca did the trick and it gradually came off (it was a beast so came off in parts!) over the course of a couple of weeks. Good luck!

Well, we tried tea tree oil for 1.5 months, but this only had a small effect on a couple of them. Then I bought H-Warts Formula. We started this one month ago and it's got rid of 4 or 5 verrucas so far! So we'll keep going with this.

@Jokat did anything work in the end?
