Good luck even finding Liquid Wrench now.
Home Depot is such a wasteland. One shit brand of every product, and that's it. Row upon row of worthless, crumbly Dap wood filler, for example.
I went there and asked three employees, probably separated in age by a decade each, for household oil. It's as if they didn't even understand the words. We're talking about 20- to 40- or 50-year-old HD employees who don't know WTF 3-in-1 oil is. Incredible.
I strongly prefer going to my local ACE Hardware or True Value Hardware before Lowes or Home Depot. Their prices will tend to be a little bit higher. However they seem to be staffed by people who know what they are doing, and Home Depot and Lowes stopped doing that entirely. I can walk in, ask the old guy working there what he might recommend and he will give me a recommendation.
