All four of the vinyl sleeves and the compilation's cover are also based on the initial art for Gloss Drop, intermixing different colored paints on the pink of the original sculpture.

[7] Slant Magazine's Kevin Liedel, in a two-out-of-five stars review, opined that "while the album's contributors lean in a well-intentioned direction, preferring organic, innovative methods over simply pasting some vocal lines and guitar riffs on top of standard, synth-driven BPMs, Dross Glop is, at best, uneven,"[9] also calling it "scattershot, meandering, awkward, and often boring".

[9] PopMatters' John Garratt said, "The best remix albums can capture the listener's imagination and take it down bold new paths.

"[16] More positive reviews came from such publications as Pitchfork, who awarded the album 7.8 out of 10, and acclaimed Hudson Mohawke's remix of "Rolls Bayce", calling it "an unexpectedly soft and emotive take from the Glasgow producer";[8] Kode9's remix of "Africastle", saying it is a "seven-minute, house-focused mini set of sorts, fizzing and grinding ominously before slamming into a kind of chiptune dancehall dance party";[8] and Qluster's "Dominican Fade", which "pairs prim horns with beautiful organ glimmers, sounding nothing like the source material but no worse for it.

"[8] AllMusic's Heather Phares gave the album 3.5 out of 5 stars, and said "Gang Gang Dance gives Gloss Drop single 'Ice Cream' one of the most playful and successful treatments, adding to it a futuristic Latin twist with dive-bombing bass, a low-rider beat, and chanting vocals," also noting that "Like many remix collections, Dross Glop doesn't flow particularly well, and it's not quite as dazzling as Gloss Drop, but it once again shows that Battles are up for anything.
