Steel wooden doors

Clean chapter -

When dealing with the stains on the surface of steel and wood doors, the soft cotton cloth is used to wipe the doors, because the hard cloth can easily scratch the surface of the doors. Special attention should be paid to the fact that the cloth soaked with neutral reagents or water should not be placed on the surface of steel doors for a long time, otherwise it will damage the surface and make the finishing materials discolored or peeled.

Solid wood door

Clean chapter -

When dealing with surface stains, soft cotton cloth is also needed to wipe the surface. When the stain is too heavy, you can use neutral detergent, toothpaste or furniture detergent. After removing the stain, you can dry it. Pay attention to the neutral reagent or water-soaked cloth should not be placed on the wooden door surface for a long time, otherwise it will damage the surface and make the surface material discolored or peeled. We should also pay attention to the edges and corners of wooden doors not to rub too much, otherwise it will cause the edges and corners of the paint to fall off.

Glass doors and windows

- decontamination section -

Glass doors and windows can be cleaned with a dishcloth covered with vinegar. If the window is covered with oil stain, you can spray the glass with cleaner, then paste a fresh-keeping film to soften the solidified oil stain. After ten minutes, tear off the fresh-keeping film and wipe it with a wet cloth.

Screen window

- decontamination section -

When cleaning screen windows, we first need to remove the window screens. Put the removed screens in the bathtub or next to the bathtub. Rinse gently with soft water pipes or sprinklers to remove cobweb, dust and other dirt on the top. Next, put some soap water in a bucket, soak some soapy water with a short hair brush, then ring gently on the screen window to ensure that the window screen has enough soap foam; finally, use soft water pipes or flowers. Rinse the soap and wait for the air to dry.

Skills of selecting parts

- Part part -

Door locks should be purchased with double-sided open safety locks. The weight of the lock is compared with the handle. The heavier the lock core is, the thicker the material is, the worse the lock core is. On the contrary, the material is thin and easy to damage. Second, look at the surface finish of the lock, whether it is fine and smooth, without spots. Repeated opening to see the sensitivity of lock core springs.

When the lock core is not flexible enough to rotate, a small amount of black powder can be scraped from the pencil core and lightly blown into the keyhole. This is because graphite is a good solid lubricant. Avoid dropping into lubricating oil, because it will be easier to stick to dust.

The floor spring of the floor spring door should be stainless steel or copper. Before it is installed and used formally, the opening and closing speed of the door should be adjusted around to facilitate its use. The hydraulic part must not leak oil. A door closer can also be used.

The movable parts of hinge, crane and caster may degrade their performance due to the adhesion of dust during long-term movement. One or two drops of lubricating oil can keep them smooth every half year or so.
