Even if you have a shorter time horizon, you will forgo significant savings opportunities by cashing out your TSP. For example, if you are 45, your $20,000 will grow to $53,855 in 17 years. Keep in mind that even if you really need the money, you may be better off borrowing from your TSP account.
Here, in NYS, rubber floor mats take a real beating during the winter. I use Hi-Temp tire cleaner (amazing stuff) and a brush to scrub the rubber, a procedure very similar to yours. Dressing-wise, I apply whatever looks good at the time, though, I've been really liking Tropi-Care's White Pearl as of late.
Rubber Plant. The rubber plant is considered one of the most effective indoor air cleaning plants. While collecting granules of dust, the rubber plant also helps to eliminate pollution indoors by absorbing carbon monoxide, carbon dioxide and other pollutants. This plant is very easy to care for -- but don't over water.
