AMAZING

Really quick delivery. Received Nanna's Secret just in time to clean the windows. What amazing results, no smears, just gleaming windows. Also cleaned the white frames, they came up a treat too. You only need a small amount of paste, it goes a very long way. 100% recommend this product and company.

Great customer service and products that actually work!

Bought a tub of Nanna's Secret cleaning product - brilliant! Have tried a vast range of products to clean the glass of my shower cubicle and I'd literally given up thinking I was ever going to get something that would rid the glass of the water marks (I live in a hard water area). Have to say, Nanna's Secret has made a huge difference, my shower cubicle no longer looks like I haven't bothered cleaning it! Customer service from Must Have Ideas was first class, the product came promptly and safely. I've just placed an order for a few more items! Brilliant!

Nannas secret

I recently purchased Nannas secret, kept seeing it advertised on social media, I have a stainless steel gas hob that I just couldn’t get clean, had marks on it that just wouldn’t come off, not anymore!!!!!!! It’s never been so clean since using this product, spotless, like new, great service to, quick delivery, efficient and professional. 5 stars from me as great service is hard to come by these days, well done Amy and team xx
