OdorCrush Clean Review: Does This Washing Machine Cleaner Actually Remove Pet Odor?

OdorCrush Clean is a washing machine cleaning tablet built specifically around pet hair, pet odor, and detergent residue buildup — a narrower, more specific pitch than a generic "washer freshener." Unlike several other direct-to-consumer products in this roundup, OdorCrush Clean's landing page actually discloses its full ingredient list, which puts it on firmer footing for this review. Here's what the product claims, what's really in it, real pricing, and what verified buyers with pets are saying.

What Is OdorCrush Clean?

OdorCrush Clean is a tablet designed to be placed directly into an empty washing machine drum (not the detergent dispenser tray) and run through a normal hot-water or "clean washer" cycle. The brand's pitch is direct: detergent alone doesn't clean the machine itself, so residue, pet hair, and bacteria build up inside the drum over time, eventually transferring back onto clothes and creating persistent odors.

The product is explicitly marketed toward pet owners, with before/after imagery on the landing page addressing mold and mildew, pet hair, general dirt and grime, pet odor, bacteria, and detergent residue as six specific problem areas.

What's Actually in OdorCrush Clean

The brand publishes a full ingredient list on its landing page, which is worth listing in full since so few competing products in this space disclose formulation details:

• Fatty alcohol polyoxyethylene
• Sodium percarbonate
• Sodium carbonate
• Sodium silicate
• Citric acid
• Sodium polyacrylate
• Alkali protease
• Tea polyphenols
• Lipase
• Alpha-amylase

Functionally, this reads as an oxidizing cleaner (sodium percarbonate is the same active ingredient found in oxygen-based stain removers) combined with a small enzyme blend (protease, lipase, amylase) that targets protein, fat, and starch-based residue — a formulation approach consistent with how the brand describes the product working on pet hair proteins and detergent buildup.

How to Use OdorCrush Clean

The brand's instructions are specific and worth following exactly as written:

1. Ensure the washing machine is completely empty.
2. Place one tablet directly into the washing machine drum — never in the detergent compartment.
3. Run on the "Normal/Hot Water" or "Clean Washer" cycle.
4. After the cycle finishes, wipe away any leftover residue.

The brand recommends repeating this every two weeks, or any time musty odors return, and states the tablets are compatible with all washer types — high efficiency (HE), front load, top load, and both stainless steel and white interior drums.

What Verified Pet-Owning Buyers Say

Several reviews specifically address multi-pet households — one reviewer with seven dogs described running two cycles on a secondary washer before testing the primary machine, reporting a noticeably fresher machine and clothes a month later. Another reviewer with two German Shepherds described using it once and seeing an immediate difference in hair and odor. The brand is also direct about one limitation in its own FAQ: the tablets loosen pet hair from the drum rather than fully dissolving it, by design, to avoid damaging the washing machine itself — a more honest and specific claim than a blanket "removes all pet hair" promise would be.

Who Should Buy OdorCrush Clean?

This is a strong fit for households with pets who wash bedding, towels, or clothing covered in pet hair and notice persistent musty odors even after a normal wash cycle. It's also relevant for anyone who simply hasn't cleaned their washing machine's interior in a long time and wants a documented, enzyme-and-oxidizer-based approach rather than a vague "freshening" tablet.

It's less necessary for someone who already runs a dedicated tub-clean cycle with a standard washer cleaner regularly and isn't dealing with pet-hair buildup specifically — the core value proposition here is targeted at the pet-owner use case.

Pros and Cons

Pros:

• Full ingredient list published — unusual transparency for this category of product
• Specifically formulated and marketed around pet hair and pet odor, not just generic "freshening"
• Compatible with all major washer types, including HE, per the brand
• 60-day money-back guarantee and a strong (614-review, 4.9/5) customer rating on the brand's own page

Cons:

• The brand is explicit that it loosens pet hair rather than fully dissolving it
• No fragrance is added, which may disappoint buyers expecting a scented result
• "Kills 99.9% of bacteria" is stated without a specific lab citation on the page

The Bottom Line

OdorCrush Clean stands out in this roundup for actually publishing its ingredient list and being specific about what its enzymes and hair-loosening action can and can't do. For pet-owning households dealing with washer odor and buildup, it's a reasonably well-documented, low-cost option backed by a solid guarantee.
