An all-natural grease busting multi purpose cleaner - in a refillable/reusable bottle! This highly concentrated Lemongrass all-natural, All Purpose Cleaner works so well we named it “Elbow Grease”. With a coconut and citrus-based formula it is toxin-free, biodegradable and septic safe – which means you can use it on all the tough jobs – indoors or out! #ToxinFreeWithLFT! Our all purpose cleaner, Elbow Grease, can be safely used in full strength on porcelain, stainless steel and the hard plastics used for toilet seats... so generally, great for bathroom / kitchen sinks, tubs, toilets and appliances. Where it gets tricky is on countertops and floors. Any surface that is porous is a no go - such as hard wood floor. The lemon in the product will strip the finish and absorb into the wood leaving that opaque white mark that you see if you cut a lemon in half and place it down on a wood surface. Even the coating on stone, marble or quartz might be porous. In these instances, our recommendation is to pump a couple of sprays while you are filling a bowl, sink or pail of hot water (it will foam up a bit) and do a spot test on a discreet location of the surface in question. Personally, we use full strength on our laminate cabinets and it works great... but you never know... so best to cautious.
