I currently have 2 bottles of Persil Small and Mighty stood next to my washing machine. It is a brand that I have used since it first hit our shelves. To start with I just used the green lidded biological version and when my girls were born I started using the blue lidded non biological one.

The bottle
Small and Mighty is available in 3 different sizes, I tend to buy whichever is on offer and currently have a medium and large. The medium bottle is 1 Litre and does 28 washes and the larger 'Family Pack' bottle is 1.89 Litres and will do 54 washes. The large bottle is quite heavy when full but has a built in handle so you can still pick it up and pour one handed. The smaller bottle is shaped to be easy to pick up but I find it more difficult than the large pack.
The back of the bottle tells you how much liquid you need for a load depending on whether you live in a hard or soft water area. Each bottle comes with a plastic dosing ball which has the 2 different levels, 35ml or 52ml, marked on it. The dosing ball just goes in your machine with the washing so there is no need to use your washing machine drawer.

How does it perform?
The biological one claims to be tough on stains and I have always found it effective at getting the odd stains we get on our clothes out. Neither myself or my husband particularly challenge this washing liquid by getting our clothes dirty, but mud or food stains have normally come out no problem.

The non biological hasn't impressed me. It is recommended that you use non biological washing liquid or powder for babies clothes as their skin is so delicate and so I chose Persil as I liked the biological version. It claims to remove the 'toughest stains' but I've found that it doesn't remove any tomato based stains or saliva which leaves a brown stain if not removed. I use a 50 minute wash at 30 degrees and Persil claim that it's unbeatable in 30 minutes at 15 degrees. I haven't found any alternative brands to work any better so I guess it is unbeatable in that sense.

It is also available in a 2 in 1 version which includes comfort fabric conditioner and a colour version.

Price and Availability
There is normally a good offer available on this product and it is widely available from supermarkets. The large bottles are currently (September 2012) £6 in Asda or 3 for £16 in Waitrose. The medium bottles are 3 for £10 at Tesco with the small bottle (18 washes) costing £3.80 at Sainsbury's. I never pay full price for this product but just stock up when Tesco have it on offer.

Would I recommend?
Yes, although it's non biological doesn't remove as many stains as I would like I haven't found anything better. It is easy to use and both will continue to be in daily use in our house.
