To do this, remove the valves and take off the bottom valve caps as well. Be careful not to get the valves mixed up.<\/p>\n<p>There are several ways of cleaning the valves and casings, just make sure that they are dry and free from any cloth particles etc.. before applying the new oil. The first time you apply the oil, use quite a lot as it also cleans the valves. Do this over newspaper or a big cloth.<\/p>\n<p>Then repeat the whole process, cleaning the valves and casing, make sure both are completely dry and only then apply the new oil again. This time, not so much and now you are ready to play.<\/p>\n<p>Generally speaking, the newer instruments have closer (tighter) clearances, requiring lighter viscosities. However, lighter viscosities tend to evaporate more quickly. So, you should be looking to use maybe a slightly heavier viscosity, that not only still gives you speed, but endurance as well.<\/p>\n<p>With time and experimenting you will eventually know how much oil suits your particular instrument.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La Tromba Fast Oil is a high-end valve, slide and key oil specially made for Monel and steel valves, keeping them fast, free and smooth.<\/p>\n","protected":false},"featured_media":76803,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[1375,443,515,606,651,1093,1128,1137,1172],"product_tag":[2486,2485,852],"class_list":{"0":"post-76802","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-baritone-horn-maintenance","7":"product_cat-brass-accessories","8":"product_cat-cornet-maintenance","9":"product_cat-euphonium-maintenance","10":"product_cat-flugel-maintenance","11":"product_cat-tenor-horn-maintenance","12":"product_cat-trumpet-maintenance","13":"product_cat-tuba-maintenance","14":"product_cat-valve-oil","15":"product_tag-fast","16":"product_tag-la-tromba","17":"product_tag-oil","18":"product_shipping_class-small-item","20":"first","21":"instock","22":"taxable","23":"shipping-taxable","24":"purchasable","25":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>La Tromba Fast Oil<\/title>\n<meta name=\"description\" content=\"La Tromba Fast Oil is a high-end valve, slide and key oil specially made for Monel and steel valves, keeping them fast, free and smooth.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/trevorjonesltd.co.uk\/shop\/product\/la-tromba-fast-oil\/\" \/>\n<meta property=\"og:locale\" content=\"en_GB\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"La Tromba Fast Oil\" \/>\n<meta property=\"og:description\" content=\"La Tromba Fast Oil is a high-end valve, slide and key oil specially made for Monel and steel valves, keeping them fast, free and smooth.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/trevorjonesltd.co.uk\/shop\/product\/la-tromba-fast-oil\/\" \/>\n<meta property=\"og:site_name\" content=\"Trevor Jones Brass &amp;
