Among granular absorbents, Cocoa Cleaner Pro is the runaway winner.
It absorbed 128.67g of oil and 237.67g of
antifreeze per cup — both firsts by a wide margin — and left the least oil
residue when cleaning a concrete floor. Zorbent finished second overall with
a 2.5 average and ZEP third at 2.8. At $27, Cocoa Cleaner Pro is also cheaper
than ZEP, Oil Dri, or Pig Granules, making it the clear pick for price and
performance.
For pads, Pig Mat finished first on the strength of
its durability: 262 oz dry and 260 oz wet tear resistance, 55 abrasion
passes, 256.59g of oil, and a pad-best 260.59g of antifreeze. But at $2.15
per mat, it costs a premium. The value pick is Spill Fighter, which posted
the highest oil capacity of any pad at 279.67g
while its bulk 100-pack runs about 43 cents per pad — roughly $1.21 per
quart of oil absorbed. Aim Pads are even cheaper per quart at about 87
cents, though they lag on durability.
Two buying cautions stand out. First, match the pad to the spill: the white
oil-only pads (Oil Eater White, Starbrite, Aim Pads, Flash Dry Pad) repel
water and absorbed under 30g of the antifreeze mix, so coolant spills call
for a gray universal pad like Pig Mat, Spill Fighter, or Auckland. Second,
skip the heavy clay: Oil Dri absorbed just 40.65g of oil per 171.36g cup,
and Dr. Elsey's Cat Litter — while a fine budget option for thin fluids —
managed only 59g of oil at roughly $2.62 per quart absorbed, more than
double the cost-per-quart of the better bulk options.
