![]() ![]() However, if other methods have proven unsatisfactory, I suppose it would be worth a try, especially if the coating formulation is acidic. This would reduce the area between the windings, with a concommitant reduction of coating thickness. I don’t necessarily recommend blasting them with baking soda – or any other media – as even with stainless steel there is a potential for some degree of etching, which one would expect would be most pronounced at the “high” spots on the wire winding. Please note that compressed air – a fast, non-contact drying technique – generally contains trace amounts of oil, and should not be employed. Once cleaned, it is imperative that metering rods be thoroughly dried before re-use, or the residual solvent may interact with the wet film coating when next used. It is important that the final rinse or wipe be done with a liquid such as water or high purity isopropyl alcohol, which will not leave a residue on the surface. Please keep in mind that this abrasive method may cause burrs on the wire, which will affect subsequent coating performance. In other cases, solvent immersion in an ultrasonic cleaning tank, along with brisk scrubbing with a very fine bristle brass brush, may be required. For non-aggressive, low viscosity fluids, simply wiping with a solvent-wetted soft, lint-free cloth may be all that is needed. The most important factor in keeping Mayer rods clean is to use an appropriate solvent immediately after every use. Would blasting with baking soda be safe and effective? Second, what is the best way to determine their overall condition?Īnswer: Thanks for the question. First, please let us know the recommended care and cleaning instructions. Question: We use your wire-wound draw down bars here, and have a couple of questions on their care, and how to evaluate their condition.
