Colin is a liquid cleaner for electrical appliances. Earlier I used to buy a liquid cleaner from a sales guy in 10 bucks. It was not effective but had no choice.
Colin which is comparatively higher in cost but is best cleaning solvent in the market. I use colin for all my electrical appliance and to clean glass door. Best thing is one spray of colin cleanses the large part of the area.
It also last for long, the handle and spray nozzle is very accurate. it releases exact amount of liquid pressed accordingly, so you dont tend to waste any liquid. Seriously, I have no idea of other, colin I saw in a retail store since then I am using it.
Verdict: It can be used for house as well as comercial purpose to clean, computers, TV, refrigerator, oven, tables and chairs. It is also easily available in the store.
