As a ujala is avery famous and well estabilshed brand in this field but my personal experience with ujala liqiud blue is not very good. It is easily availble in general store. After using it for a lomg time I found that the distribution of the colour over the cloth is not uniform. The effect of this on the cloth is very less. And the colour used in it is of very low quality. Using it is very easy becuase it is just a colour, two to four drops in half bucket of water. I dont found this liquid blue useful.
