Tackling those stubborn smelly drains and nasty buildup just got a lot easier with Quest Specialty DIGEST PLUS Foaming Drain Cleaner and Odor Eliminator. This product takes a different route by harnessing non-pathogenic bacteria that produce enzymes designed to break down fats, oils, and grease—collectively known as FOG—along with food residues lurking deep within your pipes. If your drains have been more of an olfactory assault than a simple passageway, this cleaner brings a breath of fresh air, literally, by targeting the root causes of odors and clogs.
One of the standout features of DIGEST PLUS is its thick, rich foam. Unlike liquid cleaners that sometimes struggle to reach hidden buildup, this foam expands and creeps into nooks and crannies that are usually off-limits. Plus, the 24-inch applicator tube lets you deliver the product way down into deep drain pipes, garbage disposals, grease traps, and septic tanks—places where grime loves to lurk and cause mischief. This means you’re not just skimming the surface; you’re getting down to the real problem spots.
The enzymatic action is a key factor here. The bacteria actively digest fats, oils, and grease, turning stubborn clogs and residues into harmless by-products. This biological breakdown is not only effective but also gentler on your plumbing than harsh chemical cleaners. It’s a neat way to keep your pipes clear without the risk of corrosion or damage that sometimes comes with aggressive chemical agents.
This cleaner does double duty by reducing odors as it works. Those unpleasant smells often stem from organic material trapped in the pipes, and as DIGEST PLUS breaks these down, the stench gradually fades away, leaving behind fresher air. It’s a refreshing change from cover-up scents that just mask the problem temporarily.
Another plus is that this product is made in the USA, which can give some peace of mind regarding quality and manufacturing standards. The two-count packaging means you’re equipped for multiple treatments or maintenance sessions, ensuring your drains stay in top shape over time.
Using DIGEST PLUS is pretty straightforward, too. The foam application combined with the extended tube makes targeting specific problem areas a breeze, even if you’re not a plumbing pro. Just apply, let the bacteria work their magic, and enjoy smoother, fresher drains without the stress.

The formula targets grease, soap scum, and food debris—those usual suspects behind slow drains and foul smells—working gently but effectively to keep everything flowing smoothly.
One of the standouts of this cleaner is its unique blend of enzymes and beneficial bacteria that actively break down buildup rather than just masking problems. By going after the root cause, it helps prevent future blockages and those dreaded backups that tend to sneak up without warning. Plus, it’s septic safe, so it plays nice with sensitive systems, avoiding the corrosive pitfalls of harsher chemical alternatives.
The odor-eliminating feature deserves a shout-out too.
