Please recommend an AHA toner that is effective for whiteheads.

I used to use The Ordinary Glycolic Acid, but I stopped using it for a while and put it away when I switched to a retinol product. However, perhaps because this summer was so hot, it has turned cloudy and deteriorated. It was definitely fine as recently as July. My room is indeed quite hot, but it’s annoying to have to buy a new one since it spoiled less than a year after opening. I’m thinking of trying something different this time, so please recommend any products you found to be good.

Seeing how glycolic acid worked well for me, it seems like AHA products suit me well, but I don't mind BHA or PHA products as long as they are effective!
