How to Clean a Weed Rolling Tray (Glass, Wood, Silicone)

Quick answer

Clean a rolling tray with 91% isopropyl alcohol and a lint-free cloth. Scrape loose resin first. Wipe the surface. Rinse with warm water and mild dish soap. Dry the tray before you roll. Wood trays need a damp cloth, not a soak. Silicone and plastic trays handle alcohol wipes. Glass and metal trays take a 10-minute alcohol soak.

What you need

• 91% isopropyl alcohol (70% works, takes longer)
• Mild dish soap
• Warm water
• 2 lint-free cloths or paper towels
• Soft brush or old toothbrush
• Cotton swab for corners
• Resealable bag for soaking
• Coarse salt (glass and metal only)

Steps

1. Empty the tray over a trash can. Tap the back to drop crumbs.
2. Brush dry plant matter into the trash. A soft brush moves kief and shake out of the corners.
3. Pour 1 to 2 tablespoons of 91% isopropyl alcohol onto a cloth. Do not pour alcohol into the tray.
4. Wipe the surface in one direction. Resin comes off in gray-brown streaks.
5. For sticky resin, let the alcohol sit on the surface for 2 to 5 minutes. Keep the spot wet.
6. Scrub corners and the rim with a toothbrush dipped in alcohol.
7. Add 2 to 3 drops of dish soap to a sink of warm water. Wash the tray.
8. Rinse. Hard water leaves spots on metal and glass.
9. Dry with a second cloth. Air dry 10 minutes before you roll.

Glass and metal trays

Salt works as an abrasive. Put the tray in a bag with 1/4 cup of alcohol and 1 tablespoon of coarse salt. Seal the bag. Shake for 30 seconds. Rinse. This removes baked-on resin in one pass.

Silicone trays

Silicone handles alcohol, but alcohol pulls oils out of the surface over time. Use soap and warm water after each session. Reserve alcohol for sticky residue.

Wood trays

Wood swells and cracks when it soaks. Do not submerge a wood tray. Wipe with a cloth dampened with warm water and one drop of dish soap. Dry with a towel right away. Rub food-grade mineral oil into the wood every 4 to 6 weeks.

Plastic trays

Most plastic trays are ABS or acrylic. Alcohol is safe on ABS. Alcohol clouds acrylic and can remove printed graphics. Test a small spot on the bottom first. Skip the dishwasher. Heat warps the tray and lifts the print.

What not to use

• Acetone or nail polish remover. It melts ABS and acrylic.
• Bleach. It leaves residue you can inhale.
• Steel wool and scouring pads. They scratch the surface and hold resin.
• Boiling water. It warps plastic and cracks glass with a printed layer.

How often

Wipe the tray after each session. Deep clean every 2 to 4 weeks if you smoke most days. A tray with visible resin film adds taste to flower. Clean trays keep kief from sticking, so you can save it.
