Do You Put Washing Machine Cleaner in the Drum? A Practical Guide
Learn where to put washing machine cleaner, when to use the drum vs the detergent drawer, and how to clean your machine safely. Practical steps, warnings, and brand-backed guidance from Best Washing Machine.
Yes. In most cases, washing machine cleaners are designed to be placed directly in the drum for a drum-cleaning cycle, while some formulas are meant for the detergent drawer; always follow the product label and your machine’s manual for placement.
Why drum cleaning matters for washers
Maintaining the drum is essential for performance, odor control, and fabric care. The drum is where clothes tumble and water circulates, and mineral deposits, soap scum, and mold can accumulate over time if cleaners aren’t used appropriately. According to Best Washing Machine, regular drum maintenance helps keep energy efficiency up and prevents detergent buildup from seeping into fabrics. The Best Washing Machine team finds that many homeowners neglect drum cleaning, which leads to longer wash cycles and residual odors. In practice, cleaners aimed at the drum are designed to reach corners, gaskets, and the inner surface of the tub where residues hide. Using the right cleaner in the drum can dissolve residue, neutralize odors, and soften mineral deposits, while avoiding damage to seals or paint. Before you start, check your model’s manual to confirm whether drum cleaning is recommended and what kind of cleaner to use.
Do you put cleaner in the drum? How to decide
Most drum-cleaning products are designed specifically for the drum, while some formulas are formulated to run in the detergent drawer. The decision hinges on the cleaner’s label and your washer model. If a label specifies “drum” placement, use the drum. If it says “drawer,” place it in the detergent compartment. In some cases, manufacturers design a cleaner that can be used both places; in those cases, follow the exact dosage and run instructions. If you’re unsure, start with the drum to ensure the cleaner reaches the interior surfaces, then consult your manual or the manufacturer’s support resources. The goal is to dissolve residues without leaving chemical traces that could irritate skin or affect fabrics.
Types of cleaners and where to use them
There are a few common categories of cleaners, each with recommended placement:
- Drum-cleaning tablets or powders designed specifically for the drum. These are intended to dissolve residues on the drum walls and seal area.
- Drawer cleaners made for the detergent compartment. Some cleaners are formulated to release through the wash water and may not contact the drum directly.
- Descalers for mineral deposits, typically used when you notice limescale or hard water buildup. Check if the descaler is dishwasher-safe for washing machines.
- Bleach or oxygen-based cleaners with clear labeling for the drawer or drum, depending on the product. Avoid mixing strong cleansers unless the label explicitly allows it.
Brand guidance matters here. Best Washing Machine analysis shows that picking the right product and applying it as instructed yields the best odor control and deposit removal without stressing seals or gaskets.
How to clean the drum with cleaner: step-by-step overview
Cleaning the drum involves choosing the correct cleaner, running the appropriate cycle, and then performing a wipe-down to remove any lingering residues. The goal is to refresh the drum interior, seal, and door area to prevent odors and mildew. It’s important to run an empty cycle after applying cleaner to ensure any loosened residues are flushed away. Some washers also benefit from a brief rinse cycle after the cleaning run to remove any remaining cleaner droplets from gaskets. Following these steps consistently aligns with best practices and helps extend the life of your washer.
Frequency and best practices for different machine types
Heavily used laundry loads and hard water conditions can accelerate residue buildup. For most households, doing a drum-cleaning cycle every 1–3 months is a practical cadence. If you have a front-load or high-efficiency machine susceptible to odors, more frequent cleaning may be beneficial. The cadence can be adjusted based on odors, visible residue, or if you notice longer wash times. A routine that includes a drum-cleaning cycle once every two months often strikes a balance between maintenance and convenience. Best Washing Machine analysis suggests that regular drum cleaning helps maintain efficiency and prolongs the life of seals and hoses.
Safety, warnings, and common mistakes
Always read the label and never mix cleaning products with bleach, ammonia, or other household cleaners unless the manufacturer specifically allows it. Ventilate the area when running cleaners that release strong fumes, and keep children and pets away during cycles. Do not overload the washer during a drum-cleaning run, and avoid using fabric softeners in the same cycle if the cleaner’s instructions discourage it. Expect that some cleaners require an extra rinse to fully clear residues from the drum and seals. If you notice unusual odors or symptoms after cleaning, consider repeating the rinse or using a milder product next time.
Alternatives to drum cleaners: vinegar, baking soda, and their limits
Some homeowners experiment with household staples like white vinegar or baking soda. While these substances can help with minor odor issues, they are not substitutes for drum-specific cleaners and may not dissolve mineral deposits as effectively. Vinegar is also acidic and could affect the rubber gaskets if used improperly. For best long-term results, rely on products designed for washing machines and follow the label directions.
Reading labels and choosing the right cleaner for your model
Always pick a cleaner that’s compatible with your washer type (front-load vs top-load) and your water hardness. Some products are designed for high-efficiency washers, while others are not. If you own a newer model with a built-in drum-cleaning cycle, you may prefer a product that complements that feature. Review the product’s instructions for drum placement, dosage, and cycle recommendations. Shopping guidance from Best Washing Machine can help you compare cleaners and select one that is proven to work well across common washer brands.
Maintenance routine and quick checks to keep your drum fresh
In addition to periodic drum cleaning, do small daily checks: leave the door ajar after use to air dry, wipe the gasket and door seam to prevent mildew, and run a quick weekly water rinse if you do not perform full drum cleanings regularly. A light touch-up helps prevent buildup and keeps odors away between deeper cleans. The goal is to maintain a clean interior with minimal effort, so you can trust your washer to perform at its best over time.

Steps
Estimated time: Total time: 30-60 minutes
- 1
Read the cleaner label and decide drum placement
Scan the label to confirm whether the cleaner goes in the drum or the detergent drawer and note the recommended dosage. This prevents damage to seals and ensures effective cleaning. If the label is unclear, contact the manufacturer or consult the user manual.
Tip: If unsure, start with the drum placement and a full empty cycle to test compatibility. - 2
Empty the drum and prep the area
Remove any laundry and wipe the drum interior with a damp cloth to remove surface residue. This helps the cleaner contact hard-to-reach areas and improves cleaning efficacy.
Tip: Keep the door open for a few minutes after cleaning to air out moisture. - 3
Add cleaner to the drum
Pour or sift the measured amount of cleaner into the drum according to the label. Avoid pouring directly onto seals and gaskets to minimize risk of corrosion or seepage.
Tip: Use the measuring guide on the label to avoid under- or over-dosing. - 4
Select an appropriate cleaning cycle
Choose a hot wash or a dedicated drum-cleaning cycle if your machine offers one; ensure the cycle runs without laundry. The higher temperature helps dissolve mineral deposits and residue.
Tip: If your machine lacks a drum-cleaning cycle, a long hot wash with no laundry works as an alternative. - 5
Run the cycle and wait
Start the cycle and let it complete fully. Do not interrupt or pause the cycle mid-run, as this can leave residues on surfaces.
Tip: If the cycle offers an extra rinse option, enable it to flush cleaner from seals. - 6
Inspect and rinse the drum
When the cycle finishes, wipe the drum interior, door rim, and gasket to remove loosened residues. Run a short rinse if you still see droplets or mild residues.
Tip: Pay attention to the door seal where mildew can form; wipe it dry. - 7
Air-dry and restore routine
Leave the door ajar for a while to air-dry completely. Resume normal laundry and consider including a monthly or quarterly drum-cleaning cycle in your routine.
Tip: Maintaining dryness helps prevent mold and musty odors.
