Brilliant!!
I received my order, Nanna's Secret in Orange Burst. I didn't want to do a 'full' clean, just try it. Did one of my oven racks which was bad! It took me 2 minutes to try it on one rack. OMG! Unbelievable! Wow, just Wow!! I can't imagine what else this clay could do! Highly recommend! Have ordered more including Mould cleaner and radiator cleaner. 5 Stars and more! 🎉

Nanna’s Secret
When I received my Nanna’s Secret, my first thought was I hope you can buy the applicators separately as I couldn’t see it lasting long. How wrong was I. I have chucked all sorts at it. I am now onto my second tub and the first applicator still looks as good as new. I am thinking what else I could use it for. Perhaps washing paintwork before decorating. Brilliant product all round.
