Absolutely brilliant

Absolutely brilliant for ceramic sinks and Crome taps etc… in fact on most surfaces (but I’d not use it on my marble tops) Economical, last for ages. Highly recommend

An excellent addition to my cleaning box

I have seen the Nannas secret advertised many times and made the decision to buy it to clean my oven, oh my goodness absolutely brilliant took me 15 minutes and it looked like I had a brand new oven.

I love this company

I love this company. I am happy with everything I have ordered. So far, I've had the drain sticks, mould magic, cloths, better brush and it's little friend, super scraper and nanna's secret. All of them are fab. I've tried for years to get rid of black mould on silicone in my bathroom, nothing worked. It took several applications of mould magic and it's gone. I have many more on my list. Roll on payday. One very happy customer.

Nana’s secret cream for cleaning

Nana’s secret cream for cleaning. Is definitely very very good. I would recommend it. I got extra pads, so could use say one for Kitchen & one for Bathroom. Even although the pads are very easy to clean.29

Not too good to be true it’s 100% better!

I purchased the Nanna’s Secret Fresh Lemon. I was not expecting miracles but how wrong I was. I have tried numerous cleaning products to clean the shower screen. Some leave a mess and others just don’t do a good job but Nanna’s Secret was easy to use, mess free and now my shower screen looks like new again. This product is excellent and so easy to use.

Amazing product

Delivered really quickly. Amazing product which has worked as you said it would, cooker, sinks, stained surfaces all sparkling clean after a long time of them looking scruffy and dirty. I will get rid of the majority of cleaning products and stick with Anna's secret natural cleaning clay. Love the fact that it has no toxic chemicals in it.

A very easy ordering process.

I ordered by phone as I had difficulties online. A very polite and personable lady took my order without fuss. Goods arrived very quickly as the website promises with an email to let me know they were dispatched. The product 'Nanna's Secret' is brilliant. I will order this again. Cleaned my oven as the reviews promises. The only downside of everything is the charge for postage: £3.99. I hate ordering anything which has postage charges.
