[SIZE=10.5pt]I think I got OCD. [/SIZE]
[SIZE=10.5pt]I hate scratches and cannot love anything that got scratches. It has been a problem for me for a long time. Even if I rent a car, I park it safely not to get scratched or dinged. I love to preserve the beauty![/SIZE]
[SIZE=10.5pt]It is really an art to use items whatever it may be and preserve the beauty. [/SIZE]
[SIZE=10.5pt]People wearing diamond rings, sapphire crystal watch glass, bracelet, scratch not only boomboxes but also scratch their car handle area and everywhere they stick it.[/SIZE]
[SIZE=10.5pt]There are also people with long nails... ouch!
[/SIZE]
[SIZE=10.5pt]One needs to watch what they wear while using boomboxes.
haha[/SIZE]
[SIZE=10.5pt]The only scratch I have on my like new 777 is a fine scratch on the top under the handle. I know how it got that. The seller lifted it up to show the weight....and it happened right in front of me ....from his watch...I almost cried.[/SIZE][SIZE=10.5pt]Care of boomboxes is pretty easy compared to cars that we drive on the road that is exposed to all kinds of weather conditions and ailments. [/SIZE]
[SIZE=10.5pt]Always watch the part you are trying to clean and what you use to clean it with.[/SIZE]
[SIZE=10.5pt]Paint surfaces are prone to damage easily and all depends on the quality of the paint and what you are using to clean.[/SIZE]
[SIZE=10.5pt]A brand new car gets all scratched up in the first wash if the dealer is not doing the right job. I've seen it happen many times and always warned them to give it as it is. The cleaning crew jumps in with a cloth and wipes the polycarbonate lens cover in the console area. The damage is done! You will see those hair line scratches on it on the bright and sunny day.[/SIZE]
[SIZE=10.5pt]A surface that has dust on it will make fine scratches of you use a dry cloth to wipe it. [/SIZE][SIZE=medium]Actually[/SIZE][SIZE=10.5pt] these particles act like microfine sand paper only to scratch the surface. Use a squirrel hair brush to remove the dust with gentle strokes or use a steady low pressure air blast depending on how rigid the cleaning area is. If it is chrome parts, after blowing with air use moist micro fiber cloth to gently clean the surface with light pressure. [/SIZE]
[SIZE=10.5pt]I have seen people washing their new car with a foam brush, dipping in the bucket with the debris and re using it over and over. The foam brush collects and traps dirt and sand particles in the pores and will scratch the car really bad. Also drying with beach towels will do more damage instead of using a micro fiber cloth after using n electric leaf blower to remove excess water. [/SIZE]
[SIZE=10.5pt]I thought the following link will give some idea on the hardness values. [/SIZE]

[SIZE=10.5pt]It is easy to understand what can scratch depending on the hardness values. Ceramic is not in this table and is harder than glass which makes the reason for ceramic materials scratching glass table tops. Finger nail cannot scratch glass but can scratch paint depending on how good the paint is. If it is a UV cured coating finger nail cannot scratch it and will only glide on the surface. Never try to scratch with a finger nail it on the acrylic dial glass of boomboxes, it will make scratches on it because the material is softer than finger nail. [/SIZE]
[SIZE=10.5pt]I work on developing scratch and abrasion resistance coatings and how to make additives for this application. [/SIZE]
[SIZE=10.5pt]Another important thing to consider is Heat Deflection Temperature or Heat Distortion Temperature. This is the temperature at which a polymer or plastic part deforms under a specific or known load. [/SIZE]
[SIZE=10.5pt] This property of a given plastic material is applied in many aspects of product design, engineering, and manufacture of products using thermoplastic parts and components.[/SIZE]
[SIZE=10.5pt] [/SIZE]
[SIZE=10.5pt]Now we know why the area behind the transformer of some boomboxes deform and lose shape. The engineering and research that went to boombox plastics were minimal back in the early days. [/SIZE]
[SIZE=10.5pt]Note: Microfiber cloth also comes in many grades depending on how well they are made. The good ones are really thick almost more than 6mm fiber length to either side of the cloth mesh. The ones we find at local shops like Pepboys, Menards, Home depot are much thin with a 2 mm fiber length. [/SIZE]
