Our Food and Cleaning Team (FACT) long ago determined that the best kitchen sink wand brush was the Oxo Good grips one. Unfortunately, Oxo, in a fit of insanity, has seen to discontinue this magnificent product which has led to a world-wide shortage of wand refills (they cannot be found at, e.g., Oxo, Amazon, eBay, Bed Bath & Beyond). After a pain-staking an exhausting search, FACT has found them at Target for just $3.99/pair. Unfortunately, unless you buy 8 pair, there is a $5.99 shipping. But given the dearth of supply, buying 8-pair makes sense anyhow.
