Frequently Asked Questions
Can I trim these liners to fit around pipes?
Yes — most silicone and many TPE liners are trimmable. Look for products that explicitly state trim lines or describe scissors/utility-knife trimming. Measure first and cut slowly to ensure a neat fit.
How do I clean an under-sink liner?
Lift the liner and wipe with a damp cloth or mild soap. Many silicone liners rinse easily and some are dishwasher-safe; TPE liners usually wipe clean with a non-abrasive sponge. Allow to air-dry before replacing.
Will a liner stop major leaks?
Under-sink liners are designed to contain drips and small spills long enough to notice a leak and react, but they are not a replacement for plumbing repairs. Choose thicker, raised-edge liners for better temporary containment.
