Scratches may easily be removed by polishing or by heating the surface of the material. Laser cutting may be used to form intricate designs from PMMA sheets. PMMA vaporizes to gaseous compounds (including its monomers) upon laser cutting, so a very clean cut is made, and cutting is performed very easily.
If the grass can't absorb enough water, it will turn brown and die off—often in ugly patches. Even worse, salt can build up in the soil to the point that it becomes toxic. Planting more grass ...
Killing your entire lawn gets rid of everything—grassy and broadleaf weeds, off-type lawn grasses, and the few strands of good grass you have left. Unlike the five percent household vinegar used ...
Carpet cleaning is reportedly widely misunderstood, and chemical developers have only within recent decades created new carpet care technologies. Particularly, encapsulation and other green technologies work better, are easier to use, require less training, save more time and money, and lead to less re-soiling than prior methods. [ 2 ]
A 98% biodegradable or other, [2] slightly moist absorbent cleaning compound may be spread evenly over carpet and brushed or scrubbed in. For small areas, a household hand brush can work such a compound into carpet pile; working like "tiny sponges", the attracted cleaning solution dissolves dirt, and dirt and grime is attracted/absorbed to the compound.
In general, acrylic sheet scratches easily and retains a static charge, which can be problematic when framing pastels or charcoals. Some manufacturers, add dyes to acrylic glass to filter the UV light transmittance, and its surface can also be treated with both anti-static and anti-reflective coatings .
Since phones are commonly carried in a pocket or purse with items such as keys, scratch resistance is important. There also exists a more advanced two-stage process for making chemically strengthened glass, in which the glass article is first immersed in a sodium nitrate bath at 450 °C (842 °F), which enriches the surface with sodium ions.
If your carpet has been stained by water-based paint, such as acrylic or latex paint, Osborne recommends beginning with the gentlest method: warm water and soap. 1.
