It’s actually very very quick. Just 3-4 min and what more the quantity of detergent required to wash 5 clothes is just 1 tspn. Have used it continuously for 2 years now but did not find anything to complain yet.
Type of wash I do:Hand wash.
Process I follow:
*1) Soak clothes in the surf excel quick wash solution for 3-4 mins.
2) The water level is almost always an inch above the level od the clothes.
3) Scrub extra dirty areas for 4-10 sec. (cuffs / collars/socks etc)
4) Rinse with clean water
I do not wash more that 5 clothes at a time (rarely more). And I do my laundry almost alternate days. And inspite of being so strong it surprisingly comes off easily from the clothes leaving no residue. It’s safe on hands as I don’t find my hands getting excessively dry or have any other reaction.
