How to Clean and Reuse Mr. HOBBY Bottle Pourers

Quick Answer

You can clean and reuse Mr. HOBBY bottle pourers by soaking them in Mr. Color thinner or isopropyl alcohol, then rinsing and drying. This saves money and reduces waste.

How to Clean Mr. HOBBY Bottle Pourers

1. Disassemble the pourer: Remove the pourer from the bottle. Separate the spout cap from the inner plug if your pourer has two pieces. Rinse off any loose paint with a paper towel. Common mistake: Skipping disassembly leaves paint trapped in the threads, leading to clogs.
2. Soak in thinner or alcohol: Place the pourer parts in a small container. Cover with Mr. Color thinner or 91% isopropyl alcohol. Let soak for 10–15 minutes to soften dried paint. Checkpoint: Do not use acetone on plastic parts—it may damage the pourer material.
3. Scrub with a soft brush: Use an old toothbrush or a small parts brush to gently scrub the spout, cap, and inner plug. Pay extra attention to the narrow opening where paint often hardens. Common mistake: Scrubbing too hard can deform the plastic spout. Use light pressure.
4. Rinse and dry thoroughly: Rinse all parts with warm water. Shake off excess water and let them air dry completely on a paper towel. Ensure no thinner residue remains before reassembling. Checkpoint: Moisture left inside can contaminate your paint. Drying takes about 30 minutes.
5. Reassemble and test: Once dry, snap the pourer back together and insert it into a clean bottle. Test by pouring a small amount of thinner or water to confirm the flow is clear. Common mistake: Forcing a wet pourer into a bottle can cause mold or rust on the bottle threads.

Because they sit inside the bottle, paint residue can build up around the spout and inside the cap. Regular cleaning keeps the pourer working as intended.
