Here's a breakdown of options, ranging from least to most invasive:
* Cleaning: If the rust is superficial and only on the *surface* of the plastic, you might be able to clean it with a mild abrasive cleaner like Bar Keepers Friend (oxalic acid based, follow instructions carefully). Be VERY gentle, as scrubbing aggressively can scratch the plastic. This only addresses cosmetic issues; it won't fix underlying corrosion.
* Replacing the dispenser: This is usually the best and easiest solution. The bleach dispenser is a relatively inexpensive and easily replaceable part. You can find replacement dispensers online or at appliance parts retailers, searching by your washing machine's model number. This resolves both the cosmetic and potential structural problems.
* Repairing underlying corrosion (Advanced and Not Recommended): If the rust is caused by corrosion on a metal component *underneath* the plastic dispenser, it's far more complex. This would involve disassembling a part of the washing machine, potentially requiring specialized tools and knowledge. The effort and risk often outweigh the benefits. Attempting this repair incorrectly can lead to leaks or further damage.
Important Considerations:
* Safety: Always unplug the washing machine before attempting any repairs. Water and electricity are a dangerous combination.
* Corrosion spread: Rust is a sign of underlying corrosion. Ignoring it can lead to more significant problems, including leaks and structural failure, potentially causing water damage.
* Cost vs. Benefit: The cost of a replacement dispenser is usually far less than the cost of professional repair or dealing with water damage from a neglected problem.
In almost all cases, replacing the bleach dispenser is the recommended solution. It's relatively inexpensive, easy to do (with a little DIY aptitude), and avoids the risks of attempting more involved repairs.
