Rowena W.5/5Verified
Started using 2 years ago after discovering harmful chemicals. Very good results at affordable price. Concentrated formula brilliant, better for environment. So happy!
Hannah P.5/5Verified
Brilliant stuff! Need tiniest bit so 5 litre lasts forever. Kind to skin, effective. Don't need sustained bubbles. Great value and environmentally responsible!
Matthew W.4/5Verified
Great cutting through grease, gentle on hands, good for environment. Sometimes loses foam quickly but cleans brilliantly. Best in range! Recommended to friends!
Michael C.5/5Verified
Decent with good eco credentials. Need slightly more than recommended for same power. Not as bubbly, takes getting used to. Fair price for ethical but pricier than supermarket.
George B.3/5Verified
Outstanding value! Concentrated so need tiny amount. Decant into smaller bottles, 5 litre lasts 4-5 months. Does job as well as commercial without harsh chemicals!
Benjamin F.5/5Verified
Really good! Cleans well, kinder to hands than old brand. Needs proper spout though - difficult to pour small amounts without mess. Recommend decanting to smaller bottle.
James M.4/5Verified
Perfect for us! Reducing plastic, 5 litre means refill smaller bottles for ages. No overpowering scents, gentle on skin. Doesn't foam much but cleans beautifully!
Sophie A.4/5Verified
Using for years! Cheaper than other eco brands in bulk, performs brilliantly. Fragrance-free, no chemical smells. Use for washing up, surfaces, cleaning hands!
Oliver D.4/5Verified
Better than big-name brand! Cuts grease brilliantly, handles dried egg without soaking, no residue. Tried making own but never satisfied. Finding this was fantastic!
Amelia R.4/5Verified
Shelves full of scented liquids but don't want artificial fragrances. Other eco brand damaged hands, this rescued me! No scent, no smears, hands happier. Recommended!
Andrew S.5/5Verified
Extremely good value! Concentrated so little goes long way. No strong smell on washing up. Using for months, very happy with results. Kind to skin and effective!
Lauren P.4/5Verified
My favourite by far! Right amount of foam - hate bowls full of bubbles. Cleans effectively, no residue. 5 litre really economical, lasts ages. Prompt delivery!
Charlotte W.4/5Verified
Very pleased! Lathers well, lasts long time. Love buying in 5 litre size - economical and environmental. Only downside is storage space needed but worth it!
Rebecca H.4/5Verified
Excellent product! Refill smaller bottles, sell on market stall - so popular. 5 litre manageable, no mess when pouring carefully. No waste, customers love it!
Daniel R.5/5Verified
Have chemical sensitivities, use for all dishwashing. Still need gloves but gentle formula doesn't cause headaches. Highly recommend for chemical sensitivity. Does job well!
Victoria H.5/5Verified
As good as any mainstream! 5 litre perfect for cutting plastic - refill old bottle. Not much needed for normal sink. Would absolutely recommend to others!
Christopher N.5/5Verified
Best washing up liquid I've tried! Have contact dermatitis, noticed immediate difference in gentleness. Use bit more than mainstream but worth it for skin health!
Emma B.4/5Verified
Brilliant! Using over a year, won't go back. Little goes long way - 2 teaspoons per bowl cuts grease. 5 litre lasts almost full year, incredible value!
Rachel P.5/5Verified
Absolutely love it! Have eczema, this saved my hands after years of cheap brands. Can use without gloves even with open wounds. Lather less rich but cleans well!
Thomas H.4/5Verified
Good eco option, takes adjustment. Cleans well, gentler on hands. Doesn't lather as much which feels odd. For ethical and environmental benefits, don't mind!
