So buy one battery (let say $15 out of pocket) in Nov, and recycle 10 ink cartridge in Nov (gets you $20 rewards)....so total you will get $15+$20=$35 in OD rewards, which is only good at OD.
Repeat for Dec on 1st or 2nd. Note that OD rewards should not be used for battery payment.
When people clean circuit boards with baking soda, they are using it as an abrasive paste, not the baking soda solution itself that chemically strips the contaimants. That's why the procedure below is basically neutralizing a strong base (alkali) so strong that'd eat metal with a weak acid (vinegar/citric acid), then neutralize the excess weak acid again with a weak base (baking soda) that normally won't eat metals.
Technically for non-sensitive circuits that wouldn't tolerate a little bit of cross talk from baking soda residue, you don't really have to rinse it with water. Pure rubbing alcohol doesn't dissolve baking soda so if you skip the water rinsing you might see a little bit of white stuff left on it. Nonetheless I recommend a water rinse so you don't end up troubeshooting down the line.
Buy some cheap syringes as applicators (doesn't have to be medical):
- Put a drop of citric acid on the corrosion and see it bubble and add until everything dissolved.
- Wipe the reacted salt water away with tissue/kitchen towel/cotton swabs
- Neutralize the excess acid left with a drop of baking soda each time until there are no more bubbles.
- Add a few drops of water to pick up the baking soda residue (use syringes so the water doesn't go to places you don't intend and ruin the electronics)
- Wick the rinse solution (water that picked up the baking soda residue) away
- Add a few drops of rubbing alcohol (99% if you know where to buy it. 91% can be found in groceries, 70% only if you are too cheap) to suck up the moisture and evaporate it away. The more water content in the rubbing alcohol, the longer it takes to evaporate
- You can accelerate the drying by blowing cold or warm air (less than 100 degree C please). Leaf blower works if you can grab the object tight so it won't be blown away. Or leave it out for a day before using it just to play safe.
The proper way is to take it apart and do the above, but if it's just a remote control or wireless keyboard that you have little to lose, this should do the trick.Sign up for a Slickdeals account to remove this ad.
In my experience, Duracells leaks consistently and it has nothing to do with how you use the cells or how you store it. It's a race to use up the battery as fast as you can before ticking timebomb sets off. I now believe the reason it leaks in remote controls is just because you didn't dispose the cells fast enough and it has nothing to do with whether the cells fully charged or empty.
One example is my remote control which I use every day. One day I saw white stuff coming out of it despite the remote control was still working. I immediately treated the remote control while the leak was fresh so the damage was limited. The Duraleaks are not gradual: it's an small explosive event and most people didn't notice the leaks because the battery was still working until the corrosion brought down the device before the juice was used up. The battery compartment in my remote control borders the edge of the plastic body so when the Duracell battery busted a load the whole remote bar got icky white

You can spend Rewards like individual gift cards online, or in-store they will pull up your combined Rewards total at the register and blanket apply it to your purchase, in order from oldest to newest Rewards. Any leftover Rewards balance is retained in your account. If you don't have enough Rewards to cover a transaction, you'll be prompted for additional cash/credit/whatever for the balance due. It's effectively a virtual store gift card (that doesn't count for out of pocket spending or generate additional Rewards i.e. "roll").
