The BF has uber-detergent-sensitive skin that looks like a raised relief map, if we use anything with color or fragrance. We've been using the Kirkland's Ultra Clean Free & Clear for years with good success. At my place, I use All's version of a free & clear detergent (can't recall the exact name), and the BF hasn't had any issues. We use Bounce's dye- and fragrance-free dryer sheets.
Also, I never use the 'full' amount recommended by any detergent brand. I use 1/2 to 2/3 of that amount, and our clothes still come out very clean and fresh - and without soapy residue.
