how to clean
(disclaimer: the text below is based on our personal experience and knowledge - your specific issue could be different and could require a different approach).
general remark: get rid of all the 'strong' detergents. Most of the liquid detergents contain bleach and I don't recommend using them in a kitchen environment. Most of the time soap water is just fine. If you want to use a detergent then check out the method home
laminate kitchen fronts: use some mild soap water, clean the surface and wipe it dry with a soft cloth. If you use too much soap or cleaning detergent then there will be some residue on the surface which feels like 'sandpaper'. With wiping it dry with a soft cloth you take away most of the residue and you also get rid of water spots (otherwise they will dry off itself and depending on your water quality they will leave a small spot). Do not use any detergent containing 'powder' or 'bleach' this will harm the surface.
laminate worktops: see above! If you have spots from red wine, or blueberries etc. then use a spoon full of baking soda, add some water and put the 'dough' on the spot, leave it sit over night and in the morning you can clean it with water.
wooden kitchen fronts (veneered): use some mild soap water, do not apply any pressure and wipe always in the grain direction. Here it's really important that you wipe it dry with a soft cloth. Please do not wipe it dry in circles, even the softest cloth will leave marks on the surface.
wooden worktops (veneered) like table tops: same as wooden fronts. Horizontal wood surfaces are more delicate then vertical one's. Please do not use cleaning sprays or other detergents which make the surface 'shiny'. They only make it shiny but actually don't clean. It's normal that wooden horizontal surfaces will show - over time - that they are used.
wooden kitchen fronts (solid wood): check with your kitchen manufacturer. If the front is lacquered then you can clean them like veneered fronts. If they are oiled then you will have to re-apply some oil from time to time.
wooden worktops (solid wood): clean it with soap water and wipe it dry. From time to time (probably once every 6 month) you will need to re-apply some finish (most of the time this finish is oil based). Please check with your kitchen manufacturer.
stainless steel fronts: do not use any detergent containing 'bleach or chlorine'! Just use some water - or use stainless steel cleaning detergent from method home. Even stainless steel has a grain direction - never clean in circles always clean with the grain.
stainless steel worktops: same as fronts. Over time a stainless steel work surface will look, even if you clean it regularly, 'used'. Scratches, discolorations and fingerprints are normal. But keep in mind there are (at least) two definitions of 'clean'. First of course it's the 'visible' clean - stainless steel will never be visible clean. Second there's the 'hygienic' clean - here stainless steel, even just cleaned with water -is much superior to other surfaces.
stone worktops: normally water or soap water is just fine - but there are some stone manufacturers who add a sealer on top of the surface and it could be that you have to reseal it from time to time (please check with your manufacturer). Even if it does not look like, stone is a very porous material.
