Yes, you absolutely can. Your trolley will be pleasant to stay on, the surface will be silky smooth, slightly waxed and thus easy to keep clean. Pollen and dust will not stick as it can if the surface is a little "oily".

Well, it is the case that pressure-treated wood today usually maintains very good quality, and what determines how long a "printed" wood lasts is precisely the pressure-treated wood, not the surface treatment. But you can of course influence how the surface feels and looks, if you choose soap the surface will be matte and smooth. If you choose oil, it will be shinier. 

You cannot treat a dirty surface, so first you need to clean it. This is done with warm water and soap. With a coarse brush and soap, you can remove much more dirt than you think. It is possible to "save" things that actually look a bit hopeless from the start. Give it a try before you replace the trolley, it might work! Of course, everything depends on the starting situation and the material, but you are often pleasantly surprised by what a coarse levang and soap can do.

When the surface is clean, use cold water and soap. Use a soft brush and or a cloth. Mix approx. 1l of soap with 9l of water = scrubbing bucket. The water should feel greasy from the soap. Go over the trolley and let the soap soak in. You notice when the material stops absorbing the excess fat in the soap. A new plank or a plank made of a harder type of wood will absorb less than a soft and porous plank.

It depends on the condition and type of wood. A porous, dried out pine plank absorbs more soap than a new pressure impregnated plank. But a rule of thumb is about 1l of soap / 30m2. Mix 1l of soap with 9l of water = a bucket, and the solution will be easy to handle. 

Yes, of course you can. Soap is a type of soap not a type of oil, impregnation or paint. Should you find that you have too much soap in / on the trolley, just scrub once more with only warm water and a brush.

It's a bit hard to answer without having seen it but you can definitely use the soap to clean the trolley. But whether it will absorb the excess fat and get that silky matte surface is hard to know. If the laser has clogged the wood, it will not absorb regardless of what product you put on it, but if it still "breathes" and absorbs the fat, you can certainly achieve a certain effect in any case. You will notice that quite quickly when you try it. But at least it will clean.

Whether you oil or not is a matter of taste. The surface becomes matt and smooth if soaped. If you oil, that effect disappears and the surface becomes a little shinier. If the wood is pressure impregnated, the quality of the pressure impregnation is primarily decisive for durability and longevity. It is the surface that is affected by the type of treatment you choose.

It is estimated that about 1 liter of soap is used per 30 m2

You can use our soap for both cleaning, then you use 1 dl of soap for 10 liters of VAMRT water and for treatment, then you use 1 liter of soap for 10 liters of COLD water.

It is fine to soap a trolley that has been impregnated.
