Fabulous product

I’ve been looking at getting some nanas secret for a while & wish I’d got some before now!! It’s amazing, I’ve been using this on my clients homes with incredible results, some really old lime scale & water stains on shower doors one go of this stuff & it’s all gone!! Literally like new screens. Can’t wait to get more

Good company to deal with

I saw the advert for Granny's Secret and decided to try it out. Ordering was easy and the parcel arrived in just a few days. So far, it does what it says on the label. The only down-side is that since I gave my details on the order, I keep getting messages / adverts on facebook which I do not want, so have had to block.

Nannas secret glass cleaner is a game changer. I have four glass showers and they are all sparkling as if new. A bit of effort to use but so worth it. Will definitely continue to use in the future.

Bought one storage item and went back for more!

Bought one storage item….to see if it was true what other people were saying….well what can I say went back and ordered 2 more different sets! and a Nanna’s Secret 🤫. Brilliant from start to finish and a thank you to Beth Customer Service for her help when I couldn’t see my last 2 set of orders that said delivered… neighbours had them and literally just as Beth checking door bell rings and neighbour gives us packages. Definitely will be purchasing a few other things I have seen 😃 .

Excellent service

Very quick delivery. Lots of communication regarding stages the order was at. Used Nana's Secret on the oven door. Cleaned the grease off immediately. Mould Magic did a great job of removing disgusting long term mould from the door seal of a washing machine left by a previous house owner. The products definitely work but if you are concerned about the environment, you would not want to use.

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! 🎉
