Rust remover spray CX80 CX-217 Duo Spray 500 ml — rust dissolver and penetrant

CX80 CX-217 Duo Spray 500 ml is a rust remover spray formulated to dissolve corrosion and act as a penetrant for seized fasteners and corroded parts. The product combines a fast-acting rust-dissolving agent with low-viscosity penetrating fluids to help release bolts, nuts, hinges and threaded connections while reducing friction for easier disassembly. It is suitable for automotive, industrial and household maintenance tasks where rusted metal components require freeing, cleaning and short-term protection during repair.

Advantages

The formula provides both rust dissolution and penetration in a single spray, reducing the need to use separate products. Low-viscosity components allow deep capillary action into threaded connections and tight joints, while corrosion-dissolving ingredients help break down rust for faster loosening. The aerosol delivery ensures precise application on hard-to-reach parts and offers temporary protection against further oxidation during repair operations.

Suitable for

• Freeing seized bolts, nuts and screws on vehicles and machinery
• Loosening corroded hinges, latches and door mechanisms
• Maintenance of tools and garden equipment with rusted metal parts
• Preparation of threaded connections before mechanical disassembly
• Short-term protection of exposed metal surfaces during repair

Key specifications

• Form: aerosol spray
• Net volume: 500 ml
• Function: rust dissolver and penetrant combined
• Action: dissolves corrosion and penetrates threads and tight joints
• Application method: spray with directed nozzle for targeted application

How to use

Shake the can well before use. Hold the spray nozzle toward the affected area from a distance of about 10–20 cm and apply a thin, even layer directly onto the rusted part, threaded connection or seized fastener. Allow the product to work for several minutes; for heavy corrosion, repeat application and allow longer soak time or use mechanical assistance such as gentle tapping or rotation to help release the part. After loosening, clean residue and excess product from surfaces and reassemble or replace components as required.

Usage recommendations

Use in a well-ventilated area and avoid open flames during application. Wear appropriate protective gloves and eye protection if prolonged contact is expected. Test on an inconspicuous area if surface finish or painted parts may be affected. For persistent corrosion, multiple applications combined with mechanical methods are recommended.
