Fumbling about.
I've used straight WD-40 with razors and knives and I've used 3 in 1 with knives but not with razors. I've also diluted mineral oil with WD-40 which is better than either WD or mineral straight. After finishing on my coti with baby oil the other day I think I'll be trying that on my black and see what happens.
Have you used that particular 3-in-1 with the PTFE Lubricant? It's unlike regular 3-in-1 oil.
I bought it at Lowe's and it's also sold on Amazon. I like it a lot more than the combination of mineral oil and WD-40.
Happy shaves,
Jim
