Nanna's Secret

My kitchen sink unit had got grubby over the years with ground in dirt. No matter what cleaning products I used with a lot of elbow grease thrown in, it just wouldn't shift. Known for being sceptical about everything, I reluctantly bought this thinking it was just another cleaning product that wouldn't work. HOW WRONG WAS I?! It's the best product I have ever used and I highly recommend it.

Does exactly what it said in the ad

Does exactly what it said in the ad. I used it on shower doors that were stained with water marks. Cleaned it off very well but it’s important to thoroughly rinsed and wipe off. It also worked well on the shower tray which was very slippery. Problem gone whereas other products didn’t work. All in all very pleased with the product.

Unbelievable product

So literally 5 minutes ago I got my order of Nanna's secret cleaning clay. I was so excited to try it so I set to and cleaned my gas hob and I'm gobsmacked with the result . Only used a tiny bit and hardly needed to use any pressure to apply was so easy . And result took me less than 10 minutes and it's gleaming not a mark or stain on it. It wiped off really easy then I dried it with a clean duster and I could see my face in it. Can't wait to try it on the inside of my oven.

I'm always buying innovative things from MHI. They're always good quality. This time it was Nana's secret, which I used on my glass paned doors. It worked really well and the glass was really shining after buffing. I have my eye on a lot if things that I can use it on, like doors and window frames. I'm sure I'll be buying again!

Bought lots of items from this company and loved most of them. They are delivered when they say and they are good quality and well packed. I particularly like the iron shield and Nannas secret.

Fantastic products at an affordable price

I have bought a few items recently and have t say they are all amazing! I bought the defrosting tray thinking that it can't be that good but it is now an absolute life saver in the kitchen and I don't know how I lived without it. I've just had a shower with the happy shower head, I live in an area of very hard water. My skin feels amazing and it's going to save me a fortune on shampoo. I bought a mineral shower head from a very well known online shopping site named after a rive last year for the same price, turned out to be a cheap copy which didn't work so was really happy that this one is the real deal. The toilet foam has left me speechless.........as for nannas little secret, well I guess the secret's out, just cleaned the shower door and the water is just running off. I also got an amazing free gift which I've yet to try (washing sheets for the washing machine). Will be giving them a go this weekend. What an amazing company, quality products that actually work at a price I can afford. Thank you x

Excellent Customer Service

For some reason when paying with PayPal it gave the local Homebase store as my address. I called must have ideas customer service team and they took my correct address and sent my order to me. Absolutely brilliant service. Also excellent products. The hohoho hooks are great and the cleaning clay is really effective.
