“After all the product demonstrations and loads of enthusiastic comments on the FB ads/videos, I was very encouraged but I have tried this on some stubborn stains and it's not been that good. I tried on some old, burned on oven stains but it took multiple goes with scrubbing - not the simple spray, leave it on and wipe it off as demonstrated in the videos. I also tried on some soap scum on glass shower blocks and despite leaving it on for a while, it took several goes to even make a dent. Some of them are still there. I do take the time to leave it on the stains but it doesn't seem to make any difference.”
