This is an incredible cleaner.
I used to use a competing brand from Europe that came with liquid and pills. You would put a pill into the liquid and then the contacts into the solution. This did not work well overall.<br /><br />This solution is tremendous. You do have to leave it soak for at least seven hours. And then I rinse it clear before I put them in. I have never had any burning or any other problems like some people who are not using this correctly have reported. Use it the way it says and you will have zero problems.<br /><br />One tiny complaint that I do have is that the bottle that causes the liquid to clean seems to diminish over time. By the end of the second bottle of cleaning solution, the small bottle that the contacts go into that causes the cleaning solution to work, becomes less and less effective. By the end of the second cleaning solution bottle it appears to barely be working at all. I think this is a real mistake on part of the company and they should offer us the ability to purchase more small bottles with the activator or make the activator longer lasting.<br /><br />Still, overall, this is a fantastic product.
