如何去除微波米飯和麵食中的白色污漬?


2

背景

在過去的幾年中,我在microwave中而不是在爐子上煮米飯和意大利面。這涉及將米飯或麵食放入一碗水中,然後在微波爐中使用自動米飯或麵食程序。

當我這樣做時,微波將碗中的一些水蒸氣排到微波所坐的表面上,留下潮濕的斑點。

問題

不幸的是,每次使用後我都沒有清理過濕的殘留物。結果,微波所坐的表面出現了白色斑點。微波既存在於木製家具上,也存在於層壓工作台上,並且都產生了這些白色污漬。

這是一個微弱的東西,但是如果您仔細觀察底部,您會看到很多小的白色斑點。

我嘗試過的

我嘗試了以下方法去除污漬,但這些方法均無效:

  • 用濕布擦拭
  • 用肥皂擦拭
  • 用洗碗精擦拭
  • 用醋擦拭
  • 用去殼機刮擦
  • 浸泡在餐具洗滌劑中

我沒有嘗試過漂白劑,因為我讀到它可以使家具和台式機變色。

問題

這是什麼白色污漬?是某種黴菌嗎?還是大米中的澱粉?還是其他?

The way I understand the pictures is that whatever you see is not a stain at all. The material of the furniture has wore off - i.e. it was removed due to all the humidity, heat, cleaning...

The if this is the case, then you have few solutions.

  1. Replace the element. Contract a local furniture making company, they might be willing to help.

  2. Live with it. If it is not (very) visible - maybe hidden under the microwave, then there is no harm in just forgetting about it.

  3. Apply an adhesive foil on top of the board, with any model that you choose - wood, marble, metal... Be careful that this foil might not be suitable for high temperatures - study the situation carefully first.

The stains on the wood surface look like they can be scraped off. You could try a glass cooktop scaper like this:

Don't use any force and be careful not to damage the wood. There also seem to be scratches in the wood already. I doubt you could remove the residue from them.

Don't use such a scraper on the laminated surface, it will definitely damage it.


Another possibility is the good old baking soda and acid detergent.

  • Sprinkle a generous amount of baking powder / soda over the stains
  • Add lemon juice or vinegar to the powder. You can use a spray bottle or mix and spread a paste directly on the surface.
  • Let it sit for 10 minutes before wiping it off with a moist cloth and clean water.

Another site recommends soaking the stains in olive oil for 10 minutes and then scraping the stains off with a spoon. This should work with hard, crusty stains like limestone, but from your pictures I'm not sure it's applicable here.

The second picture, the wood looks varnished, which will bloom if subjected to repeated steaming. Is the wooden top actually veneer or solid wood? It looks like permanent damage [bloom] to the varnish, which may now be penetrated, allowing limescale buildup in the wood-grain itself, making it a compound issue. I think that's a job for a sander & a new varnish… assuming it's even solid wood & not veneer, which is likely too thin to stand much sanding.

You might gain some slight improvement by treating with standard descaler [long soak for maximum penetration], then oiling or waxing the surface. That may mask it but not fix it. If the varnish is badly bloomed then removal is the only real fix.
