A4 – FORMULA 420 PLASTICS / SILICONE

This table shows how the features of Formula 420 A4 help you maintain your non-glass collection.

Understanding what sets Formula 420 A4 apart from other cleaners helps you make an informed choice.

What Makes A4 Safe For Acrylic And Silicone Pieces?

Formula 420 A4 is engineered to be non-abrasive. Some cleaners use coarse materials like salt or harsh solvents that can scratch, cloud, or weaken plastic and silicone over time. A4 instead uses a chemical action to dissolve residue. This approach protects your piece's look and structure, preventing the micro-scratches that can make it look dull.

How Is A4 Different From Formula 420 A1 For Glass?

While both cleaners are from the trusted Formula 420 brand, they are not interchangeable. A4 is the designated cleaner for plastics, acrylics, and silicone . Formula A1 is a different product designed for hard, non-porous surfaces like glass, Pyrex, metal, and ceramic . Using the right cleaner for your piece's material is crucial for effective cleaning and avoiding damage.

Get the best results from your cleaner by following these simple steps. The process usually takes just a few minutes.

How Can I Clean A Silicone Or Acrylic Bong With A4?

1. Prepare: Take apart any removable parts from your bong or rig. Rinse the piece with warm water to remove loose debris.
2. Apply: Plug any openings on your piece. Pour enough Formula 420 A4 inside to coat all soiled surfaces.
3. Shake: For light buildup, shake the piece for about one minute. This movement helps the cleaner dissolve residue quickly.
4. Soak (Optional): For heavier, caked-on resin, let the solution soak for 5-15 minutes to penetrate and break down tough spots.
5. Rinse: Pour out the used cleaner. Rinse your piece with warm water until all traces of the solution and any smell are gone.
6. Dry: Let the item air dry completely before you reassemble and use it.

While Formula 420 A4 is an excellent choice for plastics, it's helpful to see how it compares to other options in the same price range.

Using any cleaning solution properly ensures your safety and protects your accessories. Follow these guidelines for the best experience.
