Cleaning O2 sensors?

2015 Views 5 Replies 4 Participants Last post by  Toyman321
Is there a way to clean o2 sensors? My truck has been getting poor mileage and making poor power lately and I think I saw somewhere that it is possible to clean O2 sensors. Will contact electronics cleaner work, the same stuff used for MAF cleaning? Does this really help?

if you get water inside the sensor it will ruin it
