Smartora Welding Wipes are 90% alcohol for a rapid drying finish when preparing metal surfaces for welding or electrofusion. Using a single wipe to cut through grease, grime and any other possible contamination that could compromise or risk a weld. With 1″ of weld purposing to hold up to a ton in weight, these wipes are a must have to ensure an effective take between the two metals. The degreasing action combined with the rapid drying of the alcohol wicks away any moisture that could affect the join. Perfect for electrofusion & butt fusion welding.
