1 litre bottle of amazing effect foam machine concentrate. This is the only stuff available that really glows white/blue under UV lights. Our UV foam fluid is manufactured in the UK using 100% active ingredients – no water is added (as with some other foam fluids) so you are guaranteed of the most highly concentrated product available. The product has a neutral fragrance and should be mixed at a ratio of 4:100 (4%) with water prior to use. The foam produced is thick, white and with no appreciable colour – in daylight, but in a dark environment and under UV light the foam will glow with an eerie white/blue fluorescence. Our UV foam concentrate will work with all foam machines including; MBN, Universal, Strong and SFAT brands.
