If you ever thought natural, non-toxic cleaning products couldn’t replace aggressive, corrosive, toxic cleaners, Greenman is here to prove you wrong.

Formulated to replace conventional toxic products that can harm the environment and even sewage systems and toilet functionality, Greenman G WIZZ can do everything from clean surfaces to toilets and even drains and heavy grease.  It actually digests organic waste and removes odours, while being completely biodegradable and suitable for septic tanks.

works - even for my oven

I bought it to use to unclog a drain. It did not work for that so we got a plumber who took out the clogged up hairs in the basin drain. I thought it would help unclog drains but that didn't happen...I then used it as a general bathroom cleaner and it was quite good in that way really good at removing smells

This product works quite well, although every treatment does use quite a lot. Removes odours well. Works very well in conjunction with regular bicarb and vinegar treatments :)

I was very impressed with this product, it worked brilliantly on our blocked drain and is a great cleaning product for the bathrooms. Will definitely buy again.

Very happy with how well this helps in the bathroom and on though to clean places

Just came on to re order this great product and saw the last comment so thought I would add on - the product is always a watery consistency and works very well, never been any difference in the consistency of the liquid. As the owner has previously written - the viscosity of the product is not a gel - it is a liquid.

Works like a bomb love it

Leaves my garage floor clean and oil-free.

Great and works well.

Really liked this product and it worked wonder in the toilet and shower areas. Love the fact that it is great for our septic tank!
26/03/2018, By Cam
Cleans toilets very well as well as floors, especially when you have pets in the home.
19/03/2018, By Leonora
I certainly love this product - it is a repeat order. I am aware that with natural products the viscosity can be inconsistent and this does not bother me. As long as the quality of the product remains within the expected limits, it is acceptable. Factors such as temperature, humidity, light and air all impact on natural products because of the absence of toxic stabilisers. It does the job for me - atery or not

Thank you for the feedback.

Unfortunately as highlighted we had 1 bad batch of ingredient (Bacillus Spore ingredient in 1 drum were not viable) - from keeping an eye on the stock levels at Faithful to Nature there should be no more issues going forward.

To clear up the question around watery or thick concentrate - the product is a liquid - so the viscosity is not thick - it is a very watery but powerful product. Most products that are thicker are only thicker due to a thickening agent being added such as guar gum for the eco gels.

So "watery" does not equal bad. The product is a truly effective all round product that has many uses and is ideal for any home using a Grey Water system. G WIZZ can be used to dose a septic tank and keep it healthy, clean the dirtiest of kitchens - removing heavy grease all the way through to streak free windows.

It is a great pity that 1 batch had a bad ingredient or else the reviews would no doubt have remained 5 stars all the way through on efficacy.

Thank you for the ongoing support.

I am now reading the reviews of the watery product and wondering if I also got a bottle of the bad batch. Mine is also like water and I won't say I am very fond of it and wont be purchasing this again. I still got half a bottle unused. it is almost like you do not know if it is really cleaning like it says.
21/02/2018, By Max
I bought 2 bottles based on the great reviews. However, was disappointed on opening the first bottle as it was very watery rather than it being a thick concentrate as described. But as we already opened it we used it. The second bottle however was fantastic. The right consistency with amazing results. I'm ordering more right now.

Thank you Jane - luckily you commented so that I could investigate what had happened. Unfortunately my supplier had delivered a spoiled batch of ingredient. Your comment led me to have the ingredients analysed as I fully stand by G WIZZ being a great and truly effective multi use product. I apologise for the inconvenience and happy to have converted you.
18/12/2017, By Jane
the first bottle purchased was not effective and i couldn't understand why it received the rave reviews. Shortly after i initially commented i was contacted by Greenman to inquire why i didn't like the product and offered to send me a second bottle. I tried it for a second time and it definitely lived up to the hype. Cleaned heavily greased pans magically and left my bathroom sparkling. I have been converted. Thank you Greenman for such brilliant customer care.

It worked well, just didn't go very far. My bottle lasted a week, hence 3 stars.
05/12/2017, By Nicola
Read all the great reviews and was excited to use this product but unfortunately disappointed.Product was very watery, almost diluted even though it says concentrated.Cleans ok but have used better products.
04/12/2017, By David - Owner
Hi Jane - would be great if you would make contact with me as it makes zero sense to me why G WIZZ did not work for you - I am the owner and producer and take great pride in make fantastic products - so your comment is of course troubling for me and I would like to figure out how and why the G WIZZ you bought was not of an excellent standard. My details are on the bottle. Thank you.
04/12/2017, By Jane
based on the great reviews i recently purchased this. Was most disappointing. At best i will use it as a drain cleaner. Wont be purchasing it again.
25/11/2017, By Wendy
Wonderful product, replacing most of my other products with this one !
21/11/2017, By Janneke
Actually this product needs 6 leafs
21/11/2017, By Janneke
I love this product!!!!! I use it from cleaning blocked shower drains to dishwashing liquid! Not even commercial dishwashing liquid comes close to cleaning like G Wizz!! Please produce in bigger size bottles!
13/10/2017, By Zelda
This is my absolute favorite product. It is strong enough to remove really tough stains and grease but still nature friendly. I would give this an extra little leave if I could.
28/08/2017, By Leo
I've taken some advice from a review and have used about 125ml to clean my dishwasher and washing machine - pure magic! I've also poured some down the shower drain to keep it unblocked.
16/08/2017, By Mary
Love this stuff - can use it for anything; I use it in a spray bottle to spray the dishes instead of a block. Needs to rinse dishes, but it's a small price to pay for the chemicals now not going in the garden.
Using it on greasy stains in clothing and to degrease ovens or even let it mellow in the toilet before a good clean. Magic enzymes. Pity the producer changes his products so often you never know if it's still in stock or he has moved onto his next new invention.
20/07/2017, By Marelie
Terrific product. Never looking back :)
20/04/2017, By Val
Love this product, smells great and does a brilliant job. I have re-ordered.
02/11/2016, By David
Great feedback on using G WIZZ in the Dishwashing Machine - half a cap of G WIZZ or can spray between 5 - 8 times into the machine before closing - probably easier spraying it into the machine.
19/10/2016, By Val
Love it. Cleans well and smells nice an fresh. will definitely purchase again.
